CBS’s 60 Minutes will air a special two-part segment on Air Force Space Command (AFSPC) this coming Sunday, April 26, reflecting a broad array of AFSPC missions — launch, satellite operations, missile warning, acquisition, and the Joint Space Operations Center.
The GPS Directorate is a joint service effort directed by the United States Air Force and managed at the Space and Missile Systems Center (SMC), Air Force Space Command, Los Angeles Air Force Base, Calif.
“The show seldom uses two-part segments, and the producers expressed that the visually interesting nature of the mission and intellectual heft of the interviews was the deciding factor in expanding the segment beyond the normal 12 minutes,” reads an email from the Retiree Activities Office of Los Angeles Air Force Base.
Included in the segment is an interview with Brigadier General Bill Cooley, director of the GPS Directorate. Cooley was interviewed at the Boeing facility in front of a GPS IIF satellite, and will discuss the foundational nature of space to the military and economy, as well as emerging threats and how the Air Force is responding.
60 Minutes airs on CBS at 7 p.m. ET/PT. Check local listings for specific times and channels.
As I write this, the 31st Space Symposium (SS) will kickoff in just 5 days, on April 13 at the incomparable Broadmoor Resort in Colorado Springs, Colo., at the foothills of the beautiful Rocky Mountains.

If you haven’t figured it out already, the 31st SS is not a WWII German unit designation, but the 31st Space Symposium, which Dr. Neil deGrasse Tyson, famed astrophysicist, bestselling author, director of the Hayden Planetarium and host of the hugely successful television series Cosmos: A Spacetime Odyssey, simply calls “the most awesome symposium in the world.” Very high praise indeed, and a sentiment with which I totally agree.
Breaking Records
This year’s Space Symposium, which is sponsored by the Space Foundation, will be the largest ever held in terms of venue, size (number of exhibitors and speakers) and attendance. Approximately 10,000 space enthusiasts are expected to attend, and I hope you are one of them. My sources tell me the classified sessions (Cyber 1.5 and classified space sessions) are filled to overflowing — no new registrations allowed there. The exhibitor space at the Ball Aerospace Exhibit Center and Pavilion is bursting at the seams. The organizers are turning exhibitors away, so better luck next year. But if you just want to attend the greatest space symposium in the world, bar none, there is still time to register.
By the way, if you haven’t figured it out already, this is a truly international event. My sources at the Space Foundation stated that the 31st Space Symposium will have more international participation than ever, including more than 150 exhibits of the world’s latest space technology, products and services. The Ball Aerospace Exhibit Center will host more than 30 first-time exhibitors with more than a dozen countries represented, including: Austria, Canada, Denmark, France, Germany, Japan, New Zealand, Norway, Scotland, Sweden, Turkey, the UK and the U.S. The symposium is expected to attract space leaders from more than 25 countries, representing all sectors of the global space community.
Everyone who is anyone in the space world will probably be there or be represented. Consequently, the networking capabilities are unparalleled. Not to mention just being able to avail yourself of the world-famous Broadmoor Resort hospitality, plus the crisp, clean and cool mountain air at 6,000 feet.
Event Preparation
For many years, the event was known as the National Space Symposium. It outgrew that moniker many years ago, and is now simply known as the Space Symposium.
Every year before I attend the Space Symposium, I make a “ToDoToDay” list of topics I want to explore, both as a journalist and in my senior space analyst profession. Plus, of course, I make a list of people I definitely want to talk with or interview. This year, I thought I would share some of those to-dos with you, because you may indeed have some of the same interests.
GPS III
Mark Stewart, Lockheed Martin GPS III program manager (courtesy of Lockheed Martin)
Wearing my subject matter expert (SME) hat, so to speak, I recently had the honor of touring the Lockheed Martin (LMCO) Space Systems facility in Waterton Canyon (far West Denver), Colorado, where the GPS III satellites are built, integrated and otherwise readied for launch. I took the opportunity to chat with Mark Stewart and his crew. Mark is vice president for manufacturing and space systems and program manager for GPS III.
I learned that the first GPS III space vehicles (SVs) is much farther along than most everyone thinks. The problematic MDU (Mission Data Unit — the heart of the system) from Exelis has been fully tested and integrated into the payload. GPS III SV1 was only three days from being totally integrated or mated, as they say, with the on-orbit propulsion portion of the payload (the remainder of the LMCO A2100 bus) and beginning its months-long testing, certification and verification process. According to Mark, GPS III SV-01 — which powered on initially in February 2013 — now is in integration and test flow leading up to final delivery to the Air Force.
While it was thrilling to see everything finally coming together, I will also tell you candidly that the next milestone everyone is asking about, the first GPS III launch date, is probably as fluid as the Snake River in Spring. So, while I do not feel comfortable quoting a first launch date, and LMCO would not give me a firm date for delivery of the first GPS III SV, I do feel comfortable making this prediction: Barring any unforeseen major issues during testing, LMCO will be ready to deliver to the U.S. government the first ready-to-launch GPS III satellite by the end of this calendar year. That’s right, in my humble opinion the first GPS III SV will be ready to deliver to the Air Force by December 2015. When it will actually be launched is anybody’s guess; obviously, the sooner the better. Apropos of the Boeing IIF initial launches and critical on-orbit anomalies, the sooner the LMCO GPS III is put into orbit for full-scale operational and mission analysis tests the better.
LADO and OCX
The critical question of course is: Will the U.S. Air Force (USAF) have a ground control system that can successfully and reliably launch and support a full-up GPS III SV by the end of 2015? Certainly not if they stay the course with OCX, but there are alternatives, and you know who you are! Can you say LADO, Launch/Early Orbit, Anomaly Resolution, Disposal and Operations System?
Consider that LADO has been utilized to launch GPS satellites as far back as the GPS IIR-M family of satellites, also produced by LMCO, one of which was successfully launched on October 17, 2007, using the then-new LADO system. That milestone ensured the GPS program continued to provide superior space-based navigation for billions of users, military, civilian and commercial, around the globe using industry-leading highly modified (Aces Premier) commercial launch technology. This significant achievement was the culmination of outstanding teamwork between the USAF, Braxton Technologies, the engineering firm and the prime contractor.
The LADO system formed and is still the backbone of the new GPS Command and Control (C2) functionality implemented by the prime contractor. It known today as the Advanced Architecture Evolution Plan (AEP). Subsequently, LADO is now the primary launch system for all current and future (IIR-M, IIF and possibly GPS III) satellites, which should allow the U.S. Air Force to retire some outdated legacy GPS ground support and command and control systems.
The first successful 2007 LADO launch and control of an operational GPS IIR-M satellite, and the 1SOPS and 2SOPS operators’ acceptance of the GPS LADO system, was proof that commercial software can be deployed effectively even in a militarily critical mission system, saving the government both cost and schedule without sacrificing mission-unique capabilities.
In my humble opinion, that is where we need to go today. Let’s return to the tried-and-true LADO and prime contractor partnership and launch the first GPS III SV by the end of this year, or certainly by early 2016. Please notice I have not made any statements concerning scrapping the hugely expensive, 100-percent-over-budget-and-schedule (years behind) OCX program of record. Under Secretary of Defense for Acquisition, Technology and Logistics (USDATL) Frank Kendall recently announced the controversial decision that OCX as the program of record would go forward under strict scrutiny with definite milestones that must be met. Scrutiny is a fickle mistress, and historically on the OCX program, milestones are there to be missed. Meanwhile, the USAF requires a tried, proven and utterly reliable capability to launch GPS III SVs as soon as the first few become available. The USAF must place several GPS IIIs on orbit for a full checkout to ensure there are no major anomalies. Currently, LADO had an eight-year proven track record with no failures, and it remains the only program that can initiate, control and dispose of residual GPS satellites — including the IIAs, which are the longest lived GPS satellites on orbit today.
Beware, there will be many naysayers in government circles, and you may meet some of them at the symposium, that will tell you it is just not possible. But just stop by and talk candidly with LMCO Space Systems and Braxton Technologies personnel, and see what they have to say. You may be surprised by what you hear.
Then stop by the Raytheon booth and check on the status of OCX.

Female Executives in the News
Speaking of OCX and Raytheon, Lynn Dugle retired from Raytheon on March 2, 2015. Historically, Lynn has been a very capable executive. She is the former president of Raytheon’s Intelligence, Information and Services (IIS) business, which handles several key U.S. Air Force space contracts, including OCX, the current program of record for the next-generation ground system for GPS III. Dugle served as president of the division beginning in 2009.
David Wajsgras (your guess is as good as mine), Raytheon’s former senior vice president (SVP) and chief financial officer (CFO), has replaced Dugle. Wajsgras served as SVP and CFO of Raytheon Company from March 2006 to March 2015.

As a member of Raytheon’s senior leadership team, he directed Raytheon’s overall financial strategy. In my humble opinion, he has his work cut out for him. He will need all of his financial expertise and acumen to make OCX a success — financially and, hopefully, operationally. The program is grossly over budget, several years behind schedule, and reportedly, my sources tell me, far less capable than originally planned. Good luck, David.
As long as we are still speaking primarily of female executives with great track records, USAF Lieutenant General Ellen Pawlikowski, who I have had the honor of knowing and working with for the past 25 years, was recently nominated for her fourth star. General Pawlikowski successfully commanded the SMC (Space and Missile Systems Center) and served as Program Executive Officer (PEO) for Space for three years at Los Angeles Air Force Base in California. Among her many successful space acquisition programs, she was responsible for GPS procurement during her tenure.
Lt. Gen. Ellen Pawlikowski, USAF (courtesy of the USAF)
Currently, General Pawlikowski serves on the East Coast in the Pentagon as the military deputy to William LaPlante, Ph.D., the assistant secretary of the Air Force for acquisition. In other words, LaPlante is the Air Force’s Service Acquisition Executive, responsible for all Air Force research, development and acquisition activities. Previously, just to add to her mystique, General Pawlikowski spent more than one tour at the super secret National Reconnaissance Office.
When confirmed, General Pawlikowski will be only the third female four-star general in U.S. Air Force history. A well-deserved honor and one that certainly merits acknowledgement. General Pawlikowski is scheduled to speak several times at the Space Symposium, so when you see her, congratulate her on a job well done and on being nominated for her fourth star, and wish her luck in her new assignment as the head (four-star commander) of Air Force Materiel Command.
Before we leave the female leader category, my sources tell me that USAF Colonel DeAnna Burt, commander of the 2nd Space Operations Squadron (2 SOPS, the GPS squadron) from 2008 to 2010, will in June 2015 become only the third female commander of the 50th Space Wing at Schriever AFB, Colorado — home to 2 SOPS. She follows in the very capable footsteps of then-Colonel Suzanne (Zan) Vautrinot, who was the first female wing commander at the50th Space Wing followed by then-Colonel Teresa (Terry) Djuric. Note that both Suzanne and Terry, who are now retired from active duty, went on to become general officers in the USAF.
Commander AFSPC – Gen. John Hyten (courtesy of the USAF)
Currently, Colonel Burt serves as director of the Air Force Space Command (AFSPC) Commander’s Action Group for General John Hyten. General Hyten, the current commander of AFSPC, is himself a former 50th Space Wing commander, and he will also be speaking several times at the space symposium. Here’s a big hint: As a four-star general, General Hyten has morphed into quite a forceful, informative, entertaining and engaging speaker. You won’t want to miss any of his presentations.
If you see Colonel Burt at the Space Symposium, please congratulate her on her new assignment, and you might offer her your prayers for the incredible amount of responsibility she is about to assume. I’m betting she can handle it.
GPS Directorate
Another USAF general officer you are sure to run into at the Space Symposium is a newly minted brigadier general known by some as Wild Bill Cooley. General Cooley, who is currently the director of the GPS Directorate at SMC, was pinned on just a few weeks ago and will be speaking several times at the symposium. Wild Bill also deserves your congratulations. By all accounts, he is doing a great job and has more stars in his future.
The Place to Be
So, while there are several points to be made, a key one appears to be that if you are heavily involved with the GPS program inside and outside the USAF and you do a good job, it can work wonders for your career. If you want to hear from those who have been successful, the 31st Space Symposium is the place to be.
I hope to see you at the Broadmoor April 13-16. Come early and wear your walking shoes. Please stop by the GPS World booth and say hello to everyone. I will be there for sure.
As I wind up this to-do list, I will tell you about another Space Symposium event where it is important, even critical, to be seen. Everyone who is anyone will be attending the Connecting Colorado private function on Wednesday evening, April 15. The event is hosted by the Braxton Science and Technology Group; this is the third year for the coveted event. As I have stated before, I have attended 26 of the 31 Space Symposiums, and I have never been to an after-hours function during that time that even approaches the quality and class that Connecting Colorado exudes. It is a first-class event in a visually stunning venue, where private access passes are required to enter and guards are serious about keeping out gatecrashers. If history is any guide, it promises to be an amazing evening of fine wines, sumptuous food, quality cigars, roaring fireplaces and professional camaraderie that can’t be beat. Plus, the networking opportunities are endless. In other words, the Connecting Colorado event is what all the other after-hours Space Symposium events long to be or wish they could emulate. I can’t wait. I hope to see you there, and at the 31st Space Symposium. By the way, April in the Rocky Mountains means dress appropriately — warmly works for me.
Until next time, Happy Navigating, and remember: GPS is brought to you courtesy of the United States Air Force.
UPDATE: The GPS satellite has been deployed by the Delta IV rocket, completing today’s launch. The deployment occcurred as scheduled about 3 hours after launch.
The U.S. Air Force’s ninth GPS Block IIF satellite (GPS IIF-9) launched on time Wednesday at 2:36 p.m. EDT (1836 GMT) from Space Launch Complex 37 at Cape Canaveral Air Force Station, Fla.
The GPS IIF-9 rode aboard a United Launch Alliance (ULA) Delta IV rocket, which has been the workhorse of the GPS fleet for successful launches.
GPS IIF-9 is one of the next-generation GPS satellites, incorporating various improvements to provide greater accuracy, increased signals, and enhanced performance for users.
The Air Force and the 45th Space Wing supported the successful launch of the ULA rocket. This launch is the fourth ULA launch this year and the 95th launch since the company was formed in December 2006.
GPS IIF-9 launched aboard a Delta IV Medium-plus (4,2) Evolved Expendable Launch Vehicle, using a single ULA common booster core powered by an Aerojet Rocketdyne RS-68 main engine, along with two ATK GEM 60 solid rocket motors. The upper stage was powered by an Aerojet Rocketdyne RL10B-2 engine with the satellite encapsulated in a four-meter diameter composite payload fairing.
GPS Launch Workhorse. The launch marks the 29th Delta IV launch and the 57th operational GPS satellite to launch on a ULA or heritage launch vehicle. Delta IV has delivered numerous satellites for the National Reconnaissance Office (NRO), as well as GPS satellites for the Air Force and weather satellites for NASA, according to a ULA media release.
“Many thought the Delta IV and GPS days were long gone, but the recent questions concerning reliable and proven launch vehicles have brought them back online, so to speak, for GPS,” said GPS World Defense Editor Don Jewell. The upcoming (April 27) 20-year milestone for GPS space vehicles on orbit translates to approximately 500 orbital years just for the IIR and IIF constellations alone,” Jewell said. “The IIAs may account for that many orbital hours as well. Quite a record, and something of which the U.S. Air Force (USAF) and all the companies involved should be very proud.”
Yet Another USAF Success. Jewell points out that this is another successful government launch in a long string of successive launches, without a failure. “It is by far the most successful launch record ever put together by any nation or government. No other space-faring nation even comes close. The U.S. Air Force and all the players should be proud of all these records and more, plus we have one more GPS asset on orbit, providing GPS signals to the world and all they enable, courtesy of the USAF.”
“I’m elated with today’s successful launch, the GPS constellation remains healthy, strong and robust and in over 20 years since initial operational capability, GPS has never failed to deliver on its global positioning, navigation, and timing commitments,” said Brig. Gen. Cooley, director of Space and Missile Systems Center’s Global Positioning Systems Directorate.
“Each new generation of GPS satellites provides enhanced capability over the prior generations, and has delivered reliable performance demonstrating our commitment that GPS remain the Gold Standard space-based positioning, navigation, and timing service for the future,” Cooley said. “Thanks to the men and women of SMC, the 45th, 50th 310th Space Wings, Boeing, United Launch Alliance, the Aerospace Corporation, GPS IIF and Delta IV launch teams, the GPS IIF program continues to meet GPS enterprise needs.”
45th Space Wing. Once again, the 45th Space Wing team of military personnel, government civilians, and contractors provided support to the ULA launch of the Air Force Space Command mission, including weather forecasts, launch and range operations, security, safety, and public affairs.
The 45th Space Wing commander was both proud and pleased with the team she works with on the Eastern Range. “First, let me offer my heartiest congratulations to ULA, Boeing, Space and Missile Systems Center, the Launch Systems Directorate, the Global Positioning Systems Directorate, and all the mission partners who made this happen,” said Brig. Gen. Nina Armagno, 45th Space Wing commander, who also served as the Launch Decision Authority.
“What a treat — and an honor — it is to know that we have played such a significant part in something that we will celebrate two decades of helping people all around the world,” Armagno said. “Every GPS satellite since the program’s inception has been launched right here from Cape Canaveral Air Force Station safely and reliably by members of the 45th Space Wing.
“And that’s because we continue to take a ‘one launch at a time’ mentality and focus on our number one priority — 100 percent Mission Success. I am so very proud to be part of Team Patrick-Cape.”
Constellation Changes. The Air Force Second Space Operations Squadron (2 SOPS) indicates that IIF-9, SVN-71/PRN-26, will replace SVN-35 (currently being operated in Launch, Anomaly Resolution and Disposal Operations [LADO]) in the B plane slot 1F. SVN-35 is a GPS 2A-22 satellite originally launched aboard Delta 222 on August 30, 1993. It was decommissioned from active service in 2009, remained in orbit as a spare, then was set usable again in 2011. The satellite was declared unusable in 2013 and decommissioned a second time, reports Spaceflight Now. It was tested again in 2014.
SVN-38/PRN-08 will be taken out of the operational constellation prior to SVN-71 payload initialization and sent to LADO. PRN-08 will be assigned to SVN-49 in May and set to test, but is tentatively scheduled for assignment to IIF-10 to launch June 16.
SVN-35, launched on August 30, 1993, has been in a residual status since March 2013 in an expanded node slot in the B plane and successfully served 21.5 years, 14.0 years beyond its designed service life, due to the diligent efforts of the men and women of the U.S. Air Force.
SVN-51 is still in a re-phase journey from E1 (GLAN=146 °) to an auxiliary node at E7 (GLAN=60.7 °) scheduled to arrive sometime this summer.

By Colonel William T. “Bill” Cooley, U.S. Air Force, Director, Global Positioning System
The cliché “time flies when you’re having fun” accurately describes how quickly the past six months have passed for me. In a program as challenging, rewarding, and mission-critical as GPS, it is full-speed ahead all the time. As the GPS director, I am acutely aware of the importance of time — particularly high-accuracy time. Since declaring initial operational capability in December 1993, the extremely precise time service delivered by GPS has enabled numerous technological advances around the globe. While extremely proud of the accomplishments over the past 20 years, I look forward to the next 20 years, as GPS brings on new signals and continues to deliver on its promise of a worldwide free positioning, navigation, and timing (PNT) service. This article elaborates on the GPS Directorate commitment, along with the 2nd Space Operations Squadron (2 SOPS), to provide unparalleled space-based PNT accuracy, availability, and reliability to the civil community.
The first commitment, arguably the most important for users everywhere, is the commitment to high accuracy for space-based PNT. After speaking at the ION GNSS+ conference and meeting many of you in Nashville this September, I realized that some users remain worried that selective availability (SA) — the intentional degradation of public GPS signals — could return and negatively impact GPS signal quality. SA was discontinued in May 2000 to provide an increased level of accuracy to all users around the globe. Since that time, the U.S. government has adopted a policy to no longer use SA and, furthermore, in 2007 removed that function from the upcoming GPS III satellites. The GPS Performance Standard for the Standard Positioning Service reflects our commitment to accuracy by ensuring the signal-in-space (SIS) user range error remains low: better than 4-meter accuracy. Figure 1 shows the record-setting SIS accuracy and how GPS meets and far exceeds this guarantee: consistently better than 1-meter accuracy! The 2 SOPS operators who command and control the GPS satellites do a masterful job ensuring global PNT accuracy is as good as it can be.
Figure 1. Standard Positioning Service signal-in-space performance.
The quality of these services, however, does not permit the GPS enterprise to rest in the comfort of past success. We are dedicated to updating and modernizing the program.
The second commitment I’d like to highlight includes the GPS pledge for constellation sustainment and service availability. This is a guarantee to maintain a constellation of at least 24 satellites continuously broadcasting the GPS signals, providing a low dilution-of-precision value around the globe. Current efforts to meet this commitment range from replenishing unhealthy satellites to deploying improved, modernized satellites and corresponding ground support. For example, the GPS IIF satellites are rapidly becoming an integral part of the GPS constellation. With four IIFs on-orbit and a fifth soon to be launched, the constellation continues to exceed the 24-satellite requirement.
The third commitment — to modernize the GPS constellation with new signals — is best illustrated by, but not limited to, the modernized GPS IIF and GPS III satellites that are beginning to populate the constellation. In addition to four GPS IIF satellites now on orbit, the remaining GPS IIFs are either ready for launch or in final testing.
Down the road, GPS III satellites are completing development and progressing through early production. They will add the fourth civil signal, L1C, for civil users worldwide. Earlier this year, the GPS III program shipped the GPS non-flight satellite testbed (an engineering development unit) to Cape Canaveral; it successfully communicated with the next-generation operational control system (OCX), essentially as it would for launch and on-orbit check and control of functional GPS III satellites. The operational portion of the GPS ground segment, OCX Block 1 is on track to begin operations in 2016, modernizing the control segment by providing mission operation control of all legacy signals, as well as L2C and L5; later, OCX Block 2 will support L1C.
GPS civil users will soon be able to take advantage of the L2C and L5 signals that broadcast the modernized civil navigation message (CNAV); this will effectively eliminate the need to access the L1 and L2 P(Y) signals through codeless or semi-codeless techniques. These codes permit civil users to access dual-frequency solutions for precision applications (using dual-frequency enables ionospheric corrections for highly accurate PNT solutions). Compared to the L1 C/A signal, L2C features faster signal acquisition, enhanced reliability, and greater operating range. L5 will provide for increased safety-of-life applications with broadcast power even greater than L1 C/A and L2C combined, increased bandwidth, and advanced signal design. Regardless of the early availability of L2C and L5, semi-codeless users will be able to access P(Y) code — unhindered and unaffected by fully tested and vetted flex-power operations — until the end of 2020. Overall, these modernization efforts emphasize a commitment that availability surpasses simply putting satellites on orbit.
Finally, the GPS Directorate is committed to providing a high-quality service that is highly reliable. We achieve this by fielding first-rate satellites, conducting extensive test campaigns before deploying new capabilities or launching new satellites, and working closely with the operators at 2 SOPS, ensuring our constellation delivers top-quality PNT signals. An example of diligent testing is the recent live-sky test of the CNAV message on all GPS IIR-M and IIF satellites this past June. An example of a modernization feature that will enhance reliability is the capability of GPS III satellites to autonomously monitor the atomic clocks that drive the signal, thereby protecting users from clock instability and resulting signal errors.
Our demonstrated commitment to deliver accurate, available, and reliable space-based PNT allows innovators around the world to invest confidently in the creation of a multitude of GPS and GPS-enabled technologies that shape the way we live. GPS and its related technologies go far beyond letting you find the deli down the street and “checking in” to let your friends know what you’re up to on Facebook; it tracks financial transactions, enables precision farming, and allows accurate real-time updates on natural disasters such as earthquakes and tsunamis with capabilities that organizations like the NASA Jet Propulsion Laboratory and the International GNSS Service provide using GPS. The GPS Directorate is keenly aware that innovators invest their time and talent because they know they can depend on GPS availability. Our commitments are not just “feel-good” words; they are our mission and promise to the world.
I am very proud of the men and women in the GPS Directorate and thrilled to be part of this great team as the new GPS program director. The commitments listed here provide a glimpse into the services provided by the GPS enterprise. I am excited about bringing modernized signals to the world, but more excited to learn how the PNT community will use these signals to develop new innovative and useful applications. The world is easier to navigate because of GPS and GPS-enabled technologies, all of which rely on services the GPS enterprise provides: accuracy, availability, and reliability. We are committed to delivering these services as we modernize and improve the enterprise to continue GPS as the gold standard of space-based PNT.
