  • Exelis Completes Critical Data Security Work on GPS OCX System

    Exelis Completes Critical Data Security Work on GPS OCX System

    GPS OCX Logo Final_02-25-2010_large_jpgExelis has delivered three ground-based encryptors to Raytheon Company for the U.S. Air Force’s next-generation Global Positioning System Operational Control System, or GPS OCX.

    Designed to automatically code and decode GPS signals, encryptors facilitate the exchange of user information by securely transmitting navigation payload data between the OCX ground station and the orbiting constellation of satellites.

    “Following successful thermal, electromagnetic interference and security verification testing, Exelis delivered the first three of 14 encryptors,” said Kevin Farrell, positioning, navigation and timing general manager for Exelis Geospatial Systems. “Once integrated into the OCX system, the encryptors will help ensure that the next generation of GPS satellites will be ready for launch and provide advanced capabilities and security to both military and civilian users of the signal and the overall GPS modernization effort.”

    Exelis provides critical elements of software in the navigation processing subsystem that will enable controllers to better understand the exact position of GPS satellites. This helps ensure accurate navigation information is securely broadcast to users. In addition to encryptors, Exelis is building high-precision receivers for use in GPS ground monitoring stations and satellite signal simulators for testing purposes.

    As part of the overall GPS modernization effort, Exelis is also on contract with Lockheed Martin to provide payloads for GPS III satellites. Exelis is a major space technology provider, supporting both the satellite and ground portions of the GPS III modernization program.

    For nearly 40 years, Exelis payloads and payload components have been on board every GPS satellite and have accumulated more than 500 years of on-orbit life without a single mission-related failure due to Exelis equipment.

    Lockheed Martin and Raytheon Company successfully completed the third of five planned launch and early orbit exercises to demonstrate the launch readiness of the world’s most powerful and accurate Global Positioning System (GPS), the U.S. Air Force’s next-generation GPS III satellite and Operational Control System (OCX).

    Successful completion of Exercise 3, on August 1, was a key milestone demonstrating Raytheon’s OCX software meets mission requirements and is on track to support the launch of the first GPS III satellite, being produced by Lockheed Martin. Two additional readiness exercises and six 24/7 launch rehearsals are planned before launch of the first GPS III satellite in 2015.

    Using new installments of Raytheon’s OCX software and Lockheed Martin’s GPS III Launch and Checkout Capability (LCC), the Air Force Global Positioning System Directorate and the industry team completed a launch and early orbit exercise over a three-day period in late July. Exercise 3 demonstrated space-ground communications; first acquisition and transfer orbit sequences; orbit-raising maneuver planning and execution; and basic anomaly detection and resolution capabilities. In addition, the industry and customer teams jointly executed mission planning activities, such as orbit determination and the generation of upload command files.

    Exercise 3 expands on two previous exercises, with a longer mission timeline, and the introduction of simulated vehicle and ground anomalies to evaluate the combined response capabilities of the control segment, satellite and operations crew. “Successful completion of Exercise 3 clearly demonstrates that OCX is on track to support the first GPS III satellite launch,” stated Matt Gilligan, a vice president with Raytheon’s Intelligence, Information and Services business and Raytheon’s GPS OCX program manager. “The system responded as designed, and met all of the launch exercise success criteria and successfully demonstrated our anomaly response.”

    “Exercise 3 demonstrated that the cross-organizational operations team is on track to support successful GPS III launch and on-orbit checkout missions from our Newtown facility,” said Keoki Jackson, vice president of Lockheed Martin’s Navigation Systems mission area. “I look forward to the team’s continued success as they progress through the complex mission readiness program towards the first GPS III launch.”

    The Lockheed Martin-developed GPS III satellites and Raytheon‘s OCX are critical elements of the U.S. Air Force’s effort to modernize the GPS enterprise more affordably while improving capabilities to meet the evolving demands of military, commercial and civilian users worldwide.

    GPS III satellites will deliver three times better accuracy; provide up to eight times more powerful anti-jamming capabilities; and include enhancements which extend spacecraft life 25 percent further than the prior GPS block. The GPS III also will carry a new civil signal designed to be interoperable with other international global navigation satellite systems, enhancing civilian user connectivity.  The spacecraft bus and antenna assemblies for the first GPS III satellite have been delivered to Lockheed Martin’s GPS III Processing Facility and are in the integration and test flow leading to the planned space vehicle delivery in mid-2014.

    OCX is being developed in two Blocks using a commercial best practice iterative software development process, with seven iterations in Block 1 and one iteration in Block 2. Exercise 3 was conducted using the recently completed Iteration 1.4 software. Exercise 4, scheduled for early 2014, will use Iteration 1.5 software, which includes the Launch and Checkout System capability as well as all critical information assurance features needed to support launch of the first GPS III satellite.

    The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Air Force Space Command’s 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colorado, manages and operates the GPS constellation for both civil and military users.

  • Raytheon UK Receives Order for GPS Anti-Jam Prototype

    Raytheon UK has taken its first order for a pre-production MiniGAS, the latest in GPS Anti-Jam technology, designed and manufactured by the company in the U.K. This contract, awarded by an undisclosed customer, requires Raytheon UK to produce demonstrator units for customer evaluation.

    MiniGAS is the latest in Raytheon’s GPS anti-jam family of products, and it aims to be the lightest and smallest GPS anti-jamming system produced by Raytheon UK. It will have flexible form factors, suited to land, unmanned aerial vehicles and missile platforms. Raytheon is also producing demonstration units of its Landshield high performance digital anti-jam product for customer evaluation.

    As well as developing new products, Raytheon has also received an order for a further 100 of its Advanced Digital Antenna Production (ADAP) systems with the U.S. government. To date, more than 500 ADAP systems and more than 6,600 GAS-1 systems have been delivered to the U.S. government and other international customers over the course of 15 years.

    “Raytheon UK is a world leader in the production and supply of GPS anti-jamming systems to the majority of the world’s military forces,” said Richard Daniel, defence director for Raytheon UK. “These contracts and milestones demonstrate that we continue to make advancements in new systems, ensuring that Raytheon’s systems continue to meet the latest platform requirements.”

    Raytheon continues to deliver GPS anti-jam systems to Northrop Grumman Italia to be used in the Eurofighter Typhoon aircraft, and the company has also delivered a significant number of systems for the Airbus Military A400M aircraft. The company also completed the delivery of its first order for its latest GPS Anti-Jam Land product to the UK Ministry of Defence within six months of contract award.

    Raytheon Company has received Interim Authorization to Test (IATT) security certification for the Global Positioning System Next Generation Operational Control System (GPS OCX) Launch and Checkout System (LCS) four months ahead of schedule.

    Raytheon received a one-year certification with no liens, meaning the government does not require any changes. The LCS IATT certification enables Raytheon to move to the next stage of testing the Launch and Checkout System in preparation for launch of the first GPS III satellite.

    “Successful IATT certification ahead of our original schedule demonstrates not only that Raytheon meets the U.S. Air Force’s high standards for information assurance as we develop this critical national system, but also the efficient efforts of our government partners,” said Matthew Gilligan, Raytheon’s GPS OCX program manager and a vice president in Raytheon’s Intelligence, Information and Services business. “Typically IATT certification is given for six-month increments; the LCS one-year accreditation speaks to the quality of the information assurance design and threat protection.”

    The Interim Authorization to Test not only includes the LCS, but also Lockheed Martin’s GPS III satellite support systems, including the Exercise and Rehearsal Training Tool and Upload Generation Tool.

    Raytheon’s OCX and the Lockheed Martin-built GPS III satellites are critical elements of the U.S. Air Force’s effort to modernize the GPS enterprise while improving capabilities to meet the evolving demands of military, commercial and civilian users worldwide. OCX is being developed in two “blocks” using a commercial best-practice iterative software development process. There are seven iterations in Block 1 and one in Block 2. LCS is the fifth Iteration of Block 1, and it successfully completed Critical Design Review in June 2013.

    The first GPS III satellite is in production at Lockheed Martin and expected to be delivered to the U.S. Air Force “flight-ready” in mid-2014. GPS III satellites are expected to deliver three times better accuracy, provide up to eight times more powerful anti-jamming capabilities, and include enhancements that extend spacecraft life 25 percent further than the prior GPS block. The GPS III also will carry a new civil signal designed to be interoperable with other international global navigation satellite systems, enhancing civilian user connectivity.

  • Raytheon Completes International Delivery of Enhanced Paveway II GBU-50

    Raytheon Company has completed delivery of more than 200 Paveway GBU-50 guidance kits to a European partner.

    The GBU-50 provides the 2,000-pound MK-84 or the BLU-109 penetrator with all-weather GPS navigation combined with precision terminal laser guidance. A full range of selectable terminal impact angles combined with a mature combat-proven, height-of-burst maximizes the capabilities of both the MK-84 and BLU-109.

    “This delivery is a significant milestone for the Enhanced Paveway II program as it provides unique capabilities to our allies,” said Harry Schulte, vice president of Raytheon Missile Systems’ Air Warfare Systems. “As we begin our second production run of the GBU-50, we have substantial interest from the international community.”

    Each Enhanced Paveway II guidance and control section is compatible with warheads ranging from the 250-pound MK-81 to the 2,000-pound MK-84 along with the BLU-109. There is no need for the warfighter to acquire a different guidance and control section for different warhead use.

    According to Raytheon, the Paveway family of laser-guided and GPS and laser-guided bombs, has revolutionized tactical air-to-ground warfare by converting “dumb” bombs into precision-guided munitions. Paveway laser-guided bomb kits comprised more than half the air-to-ground precision-guided weapons used in Operation Iraqi Freedom, Enduring Freedom and Unified Protector.

  • FAA Awards Raytheon Two-year Contract Extension on WAAS

    The Federal Aviation Administration (FAA) has awarded Raytheon Company a two-year contract extension to continue to provide services for the Wide Area Augmentation System (WAAS), a safety system that provides satellite-based navigation in the continental United States, Alaska, Canada and Mexico. The $30.1 million contract extends the period of performance through Sept. 24, 2013.

    “Raytheon has been the FAA’s prime contractor for WAAS since the system was commissioned for operational use in the United States in 2003,” said Michael Prout, vice president of Security and Transportation Systems for Raytheon’s Network Centric Systems business. “The contract marks another milestone in the continuing partnership between Raytheon and the FAA to improve safety and efficiency for pilots.”

    According to the announcement, Raytheon will provide life-cycle support and other services to improve service reliability and availability, and increase the coverage area through system enhancements. WAAS enables GPS to meet air navigation performance and safety requirements for en route, terminal, non-precision approach, and approach with vertical guidance operations.

  • U.S. Air Force Awards Contract to Lockheed Martin for GPS III Launch, Checkout

    The U.S. Air Force has awarded Lockheed Martin a $21.5 million contract to provide a Launch and Checkout Capability (LCC) to command and control all GPS III satellites from launch through early on-orbit testing.

    The LCC, which will be integrated into the Raytheon-developed Next Generation Operational Control System (OCX), will ensure launch availability for the first GPS III satellite in 2014. The LCC includes trained satellite operators and engineering solutions in partnership with OCX to support launch, early orbit operations and checkout of all GPS III satellites before the spacecraft are turned over to Air Force Space Command for operations.

    “Achieving initial launch capability in 2014 is critical to introducing new GPS capabilities on time and will  enable the GPS III program to continue its production pace, maximize efficiencies and reduce long term costs for the GPS enterprise as a whole,” said Colonel Bernard Gruber, director of the U.S. Air Force’s Global Positioning Systems Directorate. “The Launch and Checkout Capability will ensure we can launch in 2014, effectively closing the time gap between GPS III and the Next Generation Operational Control System.”

    The GPS III program will replace aging GPS satellites while improving capability to meet the evolving needs of military, commercial and civilian users worldwide. The satellites will deliver better accuracy and improved anti-jamming power while enhancing the spacecraft’s design life and adding a new civil signal designed to be interoperable with international global navigation satellite systems, according to Lockheed Martin.

    The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the GPS III prime contractor with teammates ITT Exelis, General Dynamics, Infinity Systems Engineering, Honeywell, ATK and other subcontractors. Air Force Space Command’s 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colo., manages and operates the GPS constellation for both civil and military users.

  • Raytheon Interview: GPS OCX Program Status

    Don Jewell, our intrepid Defense editor, finally stopped traveling long enough to catch up with Robert “Bob” Canty, the Raytheon vice president and program manager for the GPS OCX program. They managed to find time for a very interesting and uplifting conversation concerning the history, current status, and way ahead for the next-generation GPS operational ground control segment. Uplifting because, incredibly, this critical space program is actually on schedule and on budget. Alert the media and roll the presses!

    DJ (Don Jewell): Bob I really appreciate you taking the time to sit down with GPS World and talk about OCX which is the future GPS Operational Ground Control Segment located at Schriever AFB in Colorado.

    BC (Bob Canty): Don, I am always happy to talk about OCX. The program is doing extremely well and it is a good space story to tell.

    DJ: Great, Bob. Now, historically, exactly how long has the Raytheon OCX team effort been in place? By that I am referring to the fact that Raytheon was required to prepare some amount of operational software for the last demo phase during the OCX competition, before contract award, that would supposedly be used at a later date. Are you making use of that software, and if you count that time during the competition phase, exactly how long have you or your team been working the OCX program?

    BC: Don, what’s interesting is that we (Raytheon) were involved all the way back in the SARD (System Architecture and Requirements Definition) days, the early 2000s. I have personally been involved since the SARD days as well when we were supporting the Spectrum Astro and the Boeing teams. Then, after the SARD phase, the Spectrum Astro team joined the Lockheed Martin team, so then we were supporting Lockheed Martin (LMCO) and Boeing in that phase. When the space and control segment competitions were separated we had a PRDA (Program Research and Development Announcement) team, and consequently our team has been together since 2005. So our team has been around GPS a long time…when we came into the last phase, which was Phase A, of the program our team had a very mature design and a very mature approach. The Raytheon team was integrated and had many of the process steps behind us when we came into Phase A.

    Essentially, we designed in Phase A the ability to be able to reuse that software in Phase B, so 97 percent of the software we developed in Phase A is being reused now in Phase B. Now, because of our reuse heritage, we have reuse from many different programs. We were able to incorporate that experience into Phase A and deliver a significant amount of code. Just from a DSLOC (Delivered Source Lines of Code) standpoint, on the order of 40 percent of the Block 1 code is completed and integrated together. When you look at equivalent source lines of code, or how much effort it took us to put that DSLOC together, it was about 75,000 lines of code. So when I take a look at all the code that AEP/LADO (Architecture Evolution Plan [current GPS ground control system]) has as delivered source lines of code, our final program will have less than half the lines of code than are currently in operations with the AEP/LADO program.

    Now to get back to your original question about Raytheon’s longevity with the OCX program. In November 2007, Raytheon won a $160 million Phase A System Design and Risk Reduction contract. In February 2010, just 12 months ago, Raytheon was awarded a 73-month, $886 million contract for Blocks 1 and 2 of the GPS Advanced Control Segment (OCX). Raytheon has been working the next-generation GPS control system for more than 10 years. Now the Raytheon team, as such, has been in place since the PDRA phase so we have worked together for over five years. By establishing our technical approach and processes prior to Phase A, we were able to move very quickly into maturing our system design. This allowed us to develop software that is reusable in Phase B.

    DJ: That’s great Bob, but why the smaller overall amount of code? Are you just utilizing a more modern and efficient software development language?

    BC: Right, Don, it has to do with the overall efficiency of the code and the way it is architected and designed. There are many things we are doing with this particular code. Specifically we build functionality once and use it in many places in the architecture. By understanding the complete construct of what we have to deliver, we can get a tremendous amount of efficiency by the way we architect the overall SW and reuse pieces. We build once and deploy in several different places.

    DJ: That sounds like very efficient code, Bob. What exactly is the primary software development language the Raytheon team is using?

    BC: It is primarily C++ and Java.

    DJ: So that must make it easier to follow sequences and find errors and problems in the code.

    BC: It does, and from an integration standpoint, the overall modularity approach of a Service Oriented Architecture (SOA), facilitates integration. An SOA done right, and they aren’t all designed correctly, partitions code into much smaller modules with standard interfaces that makes it easier to integrate and test. Plus, in older architectures, you had to integrate all the code together before you could find problems among modules. In today’s OCX architecture you can really isolate problems down to different layers in the architecture, which also makes it much simpler to integrate and test.

    DJ: It certainly sounds like OCX software will be easier to maintain. And I think you mentioned to me before that there will be no reuse of the AEP software in the OCX code.

    BC: Right. We have no AEP code in our architecture at all. We are, however, reusing some parts of the LADO (Launch and Early Orbit, Anomaly Resolution, and Disposal Operations) software. Some of the software code that Braxton has, especially for modeling and simulation — and I will talk more about that in a minute — is being validated in our modeling and simulation framework. We are bringing all that reuse of Braxton software into our overall offering.

    Essentially, Don, the entire OCX architecture was designed to easily evolve to accommodate new functionally, automation and changes in the mission CONOPS (Concept of Operations). It is also a very efficient design. Our design will use less than half the lines of code as AEP/LADO with twice the capability. As I said, we purposely did not reuse any AEP software. We have taken advantage of Braxton’s validated LADO IIR, IIR-M, and IIF models. Raytheon is also taking advantage of our Eclipse Command and Control and Equinox Mission Management product suites. ITT reuses designs from its GPS IIR, GPS IIR-M, and GPS IIIA , and Raytheon’s NCS (Network Centric Systems) brings reuse from the FAA’s (Federal Aviation Administration) Wide-Area Augmentation System better known as WAAS.

    DJ: I guess that makes sense, and it’s obviously more economical for cost and schedule to automate and reuse software where you can. And since you mentioned LADO, many of the 2SOPS (2nd Space Operations Squadron) operators tell me that they prefer to use the Braxton LADO system and software because so much of it is automated. It does away with human interpretation and is less prone to fat fingering errors, especially during times of high-operations tempo on the operations floor at Schriever AFB.

    BC: Absolutely. In our system going forward, we are bringing more automation into play. As you start bringing in NAVWAR (Navigation Warfare) in Block II, the overall goal is to have the same or a fewer number of operators than are on the GPS operatio
    ns floor today. We are essentially doubling the operational capacity with the same or a fewer number of people. We are introducing much more automation into OCX program, more even than the Braxton LADO program has today.

    DJ: We’ve talked a lot about software and procedures, but is the OCX program also about hardware?

     

    BC: You’re right, Don. Although the GPS OCX contract is primarily a software development effort, there is a significant amount of hardware. Approximately 20 percent of the effort is hardware. In addition to the computer equipment that will support operations at the primary and alternate Master Control Stations (AMCS), we will be installing new GPS receivers in 17 globally distributed monitoring stations to monitor all GPS signals, and upgrading the ground antennas at all four legacy ground antenna (GA) locations. Most of it is COTS (commercial off the shelf) hardware, the only exception being the receivers that we put in the monitoring stations. They are custom built receivers in order to get the performance we are looking for. Since we are incorporating the M-Code (military-only code) capability into the receivers, we are required to go through an intensive information assurance (IA) accreditation process. So that is really the only custom piece of hardware out there as far as OCX is concerned.

    DJ: Does that mean that you are going to have to certify all new hardware to prove that it will operate with OCX?

    BC: Actually, no, there are only two segments of the hardware program that are going to have to be certified, and that is the GPS monitors/receivers and the key management system.

    DJ: Key management… Does that mean that you are currently working the SAASM (Selective Availability Anti-Spoofing Module) OTAR (over the air re-keying) and OTAD (over-the-air delivery) piece of the GPS control system as well within the OCX program?

    BC: Correct.

    DJ: And now the question that everyone wants answered; is the OCX program still on schedule? Will it be delivered on time?

    BC: We are on schedule and on cost. Since contract award in February 2010, we have successfully completed our Technical Baseline Review, Integrated Baseline Review, Software Specification Review, and Hardware Preliminary Design Review. We are on track for a successful system PDR in the second quarter of calendar year 2011 (2Q11). We just completed software iteration version 1.2 integration and test. We have started software iteration version 1.3 design activities so we are right on schedule. As I mentioned before, since we had a lot of code reuse coming out of Phase A, we were able to incorporate 97% of it into our iteration version 1.2 of the software baseline. We will progress all the way to version 1.7 in our software iterations for Block 1, so essentially we are currently a little less than a third of the way through our software development activity. We completed iteration 1.2 right on the day it was scheduled in our original operational baseline schedule. Starting this week we are beginning our iterative software design for iteration version 1.3 and that is scheduled to complete in the fall of 2011. So, yes, right now on the software development side we are right on schedule.

    DJ: Bob, anyone familiar with the OCX and GPS IIIA programs has heard about a supposed gap or lack of synchronization between the two programs. Is there still a gap between the OCX FOC (full operational capability) date and the proposed launch date for the first GPS IIIA satellite? If so, how large is that gap and is it getting bigger or smaller?

    BC: Don, the first GPS IIIA satellite is currently scheduled to launch in May 2014, and the OCX Block 1.0 Ready To Operate (RTO) date is August 2015. Over the past six months, we have worked closely with the GPS Directorate and GPS IIIA contractor Lockheed Martin (LMCO) to align our schedules and ensure OCX is ready to support the first IIIA launch. This has required the introduction of a streamlined Launch and Checkout System (LCS) designed to:

    • Reduce schedule risk for OCX Block 1.0 RTO through early completion of GPS IIIA integration, test, exercises, and rehearsals.
    • Provide earliest GPS IIIA-1 operational availability.
    • Provide opportunity for discovery of potential IIIA-1 design issues.

    LCS will provide Block 1.0 Initial Checkout Capability in April 2013, On-Orbit Checkout Capability (spacecraft only) in March 2014, and Full Checkout Capability (spacecraft and navigation payload) in March 2015 (in time for the scheduled IIIA-2 launch). With LCS we have essentially closed the gap between GPS IIIA launch and OCX Block 1.0 delivery.

    DJ: Great. You have theoretically closed the gap as long as LCS comes to fruition. Barring that, if required, could LADO launch the first GPS IIIA satellite?

    BC: The LADO system does not currently support the IIIA vehicle and, ultimately, it is not about launching GPS IIIA as much as it is about bringing it into operations. OCX is the only system that can bring GPS IIIA into operations. Raytheon feels the current LCS approach significantly reduces the operational risk to GPS IIIA.

    DJ: Now, Bob, as we mentioned earlier Raytheon has put together a team. You are not doing this alone, so please remind us of who your initial teammates were and are they all still on board? Have any new teammates been added and what does each teammate specialize in as far as OCX support is concerned?

    BC: Actually, we maintain the same team today with which we started the OCX contract. Raytheon‘s teammates include Boeing, ITT Corporation, Braxton Technologies, Infinity Systems Engineering, and the Jet Propulsion Laboratory. Details on each partner and its role in the GPS OCX program are as follows:

    DJ: Is the Raytheon team going to design a new Kalman filter for OCX? [Editor: for those who aren’t aware, a Kalman filter is not a hardware device but rather a set of sophisticated processing algorithms.] And if so, how do you envision the transition process progressing? Is this an area of special concern? And would Raytheon build the Kalman filter or would it be one of your teammates? If so, which one and why?

     

    BC:I think you just asked me six rapid-fire questions about the Kalman filter.Yes, we are designing new Kalman filter algorithms for OCX. Our Jet Propulsion Laboratory (JPL) teammate, with extensive experience in this area, is responsible for developing the Kalman filter algorithms and ITT Space Systems is integrating the algorithms into the OCX navigation solution. Based on past experience, we are developing a very robust and flexible transition plan in which the Kalman filter can be operated in parallel and switched in and out even after long periods of operations. We believe this will facilitate a smooth transition from the current GPS AEP OCS to OCX.


    DJ
    : Bob, if you don’t mind, I would like to go back to the gap issue for just a moment, just to make sure there are no misunderstandings. According to LMCO, the GPS IIIA program is continuing to move to the left, so much so that the first IIIA launch might take place before the last IIF launch. Will this cause OCX any special problems?

    BC: Don, as stated before, the first GPS IIIA launch is scheduled for May 2
    014 and we do not anticipate any schedule problems.

    DJ: That’s great. Not to beat a dead horse, but that is a question we get a lot at GPS World, and I just wanted to make sure we had it covered. Now to move on, have there been any major surprises in the program so far, good or bad?

    BC: I have been very pleased with the collaboration efforts among the GP (GPS Directorate), SE&I (Systems Engineering and Integration), GPS IIIA, and OCX contractors. The cooperation, data sharing, and teaming are outstanding. Bringing in a diversity of views and solutions is really enhancing the program.

    DJ: Bob, is there a particular aspect of the OCX program of which you as the PM (program manager) are particularly proud?

    BC: There is. As identified earlier, we are proud to be on schedule and on cost. We have an outstanding team that is executing to meet the customer’s needs. The strong relationship we have built with our teammates, with Lockheed Martin, the GPS IIIA contractor, and our SMC customer has been vital to the success of the program to date. In addition, we believe the ability to design a solution that leverages significant software reuse has proven invaluable to reducing cost, schedule, and technical risk on the program.

    DJ: Sounds like the A-Team motto, “I love it when a plan comes together.” But what about the future, the way ahead for OCX? Is the government continuing to add requirements as you go along?

    As you know many PMs have seen their well-planned programs fail because of continuous government change requests.

    BC: Actually, Don, the requirements have been very stable on Block 1 and 2 for OCX. As for the future of OCX, the net-centric features that will be enabled by OCX will revolutionize future GPS services. We anticipate new capabilities such as:

    • Net-centric GPS user equipment will enable delivery of future GPS OCX net-centric services (e.g., situational awareness, augmentation, differential GPS) directly to end-users.
    • Net-centric user equipment and the future ISR (intelligence, surveillance, reconnaissance) sensor “cloud” will close the loop for GPS forward monitoring for assured delivery of PNT services and for identifying, locating and reporting sources of interference.
    • Collaborative, effects-based decision support tools and ad hoc planning coupled with an integrated space/ground network will tighten the NAVWAR and integrity timeline.
    • Combined planning of space, air, and ground-based L-band augmentation assets for assured PNT (position, navigation and timing).
    • Secure, cross-domain collaboration and GPS mission situational awareness will provide efficient user help-desk services and automation for constellation management.
    • Standards-based developer’s toolkits will speed delivery of new capabilities to users and ensure future interoperability.

    DJ: OK, Bob, OCX may be flashy, new, on schedule and on budget as well as being projected to be more efficient. But as the PM what do you consider to be the most impressive or critical new capabilities that OCX brings to the GPS control system and to the warfighters?

    BC: GPS OCX consolidates all ground system operations into a single, flexible, service-oriented architecture (SOA) solution that meets the needs of both legacy and future satellites. GPS OCX offers the capability to optimize across all elements of the space segment and provides net-centric interfaces and services to improve civil and commercial capabilities and enhance warfighter effectiveness well into the future.

    GPS OCX will act as a service bridge between space and user segments, enabling a more innovative, user-centric system including:
    Improved availability of signals from space

    • Increased accuracy of data
    • Flexible modern software that is easier to maintain and modernize
    • Timely clock and calendar updates
    • Enhanced anti-jam and interference performance
    • Increased capacity for satellite support
    • Increased Situational Awareness for GPS operators
    • Syncs with current satellites and future satellites
    • Performance continuity with existing GPS devices.

    GPS OCX will revolutionize command and control (C2) and mission capabilities for U.S. armed forces and our allies, transforming the focus of GPS operations from satellite C2, to user-oriented, effects-based operations. The program will increase operational efficiency by supporting network-centric capabilities, navigation warfare, and effects-based operations (EBO), while providing the war fighter secure, actionable and predictive information to enhance situational awareness, real-time decision-making, and responsiveness.

    DJ: Bob, what can you tell us about the new Raytheon GPS collaboration facility that is scheduled to open sometime this month in El Segundo, California? What part will that facility and its capabilities play, if any, in the OCX process going forward?

    BC: Don, bringing new GPS capability on-line is directly related to when the control segment (OCX) can transition the capability to everyday operations. We recognize that close collaboration is necessary for enterprise success. The GPS Collaboration Center will be used for OCX development and deployment in addition to demonstrating future GPS capabilities from across the Raytheon Corporation and the OCX team.

    DJ: Well Bob I’m certainly impressed and I want to thank you once again for your time today. This is an impressive story. There aren’t many space programs today that are on their cost and schedule budget or anywhere near it for that matter. That in itself is an amazing achievement. Any closing comments or important questions we forgot?

    BC: Don, I appreciate the opportunity to talk about the OCX program and in closing I want to say that GPS OCX, the next-generation operational gateway service, is designed to provide secure, accurate, and reliable navigation and timing information to effectively support military, commercial, and civil users. GPS OCX will act as the service integrator for ground, space, and user segments to enhance mission command and control, and situational awareness capabilities, while seamlessly supporting millions of users around the world.

    Raytheon IIS brings more than four decades of high-availability, precision-based, and command and control systems experience to GPS OCX. In addition, Raytheon IIS understands the need to move from a platform-centric to a user-centric system, and is able to deliver capability upgrades in an asynchronous environment and support the government’s desire to operate as a systems integrator. As the prime contractor for the GPS OCX program, Raytheon will continue to ensure that the solution is delivered on time, and on budget.

    OCX will replace the current GPS Operational Control System, maintaining backwards compatibility with the Block IIR and IIR-M constellation, providing command and control of the new GPS IIF and GPS III families of satellites, and enabling new modernized signal capabilities.

    “OCX is urgently needed not only to enable new warfighter capabilities but also to put the new GPS III space vehicles into mission operations,” said Col. Dave Madden, commander, GPSW. “OCX will have a flexible architecture that can rapidly adapt to the changing needs of today’s warfighter and will connect to the Global Information Grid so that warfighters around the globe have immediate access to GPS data and constellation status.”

    “OCX will allow AFSPC to effectively and efficiently plan and control full-spectrum precision position, navigation and timing information for all GPS user communities,” Madden said. “OCX will achieve this vision by implementing an incremental development approach that supports the evolving military operational environment, while enabling civil and international users who are employing GPS in innovative applications like transportation.”

    The Air Force Space Command’s Space and Missile Systems Center, located at Los Angeles Air Force Base, California, is the U.S. Air Force’s center of acquisition excellence for acquiring and developing military space systems including six wings and three groups responsible for GPS, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control network, space-based infrared systems, intercontinental ballistic missile systems, and space situational awareness capabilities.

  • Raytheon Scores GPS Modernized User Equipment Contract

    Raytheon Co. has won a $61 million U.S. Air Force contract from the GPS Wing to complete the development and certification of next-generation GPS receivers.

    Under the Modernized User Equipment (MUE) program, circuit card technology will connect military users with new GPS navigation signals used in forthcoming enhanced GPS satellites. The receivers, which will be able to read the new M-code military signal, also will work effectively with legacy signal systems, Raytheon said.

    “The MUE program is raising the capability of military GPS equipment while lowering the cost for the warfighter,” said Phil Kelton, MUE program manager for Raytheon’s GPS and navigation systems business. “Raytheon’s approach to MUE takes advantage of breakthroughs in microelectronics technology, coupled with advanced security solutions to enable higher performance and greater integrity at less cost than today’s systems.”

    Kelton sees potential to achieve “true force-enhancing status” for military GPS capability though the proliferation of low-cost GPS modernized user equipment, according to the company. Raytheon is teamed on the program with General Dynamics and Trimble Navigation Systems.

    “The award of this second phase of the systems design and development contract allows us to complete the custom building-blocks being developed for the next-generation M-code GPS receivers,” said Michael Crisp, director of Raytheon GPS and navigation systems. It is developing two different form factors for receiver cards; this will allow modular upgrades of Raytheon’s avionics, weapons and integrated sensor systems ahead of the full deployment of the GPS III satellite constellation, Crisp said.

    In December of last year the U.S. Air Force also exercised a $50.7 million contract option with another contractor, Rockwell Collins, to complete part of the next phase of the MUE program. That work consists of receiver card development for ground and airborne applications, including test and security certification for next-generation GPS technology.

    The Air Force awarded the initial MUE contract of $27.9 million to Rockwell Collins in 2006 to develop and demonstrate user segment receiver cards, establishing the first proof of design for the future GPS architecture. That contract, executed through October 2007, supported preliminary design of the modernized receiver cards.
