CAST Navigation LLC has developed the capability to support development and implementation of the Modernized Navstar Security Algorithm (MNSA). The U.S. Department of Defense granted in January CAST MNSA security approval, enabling its simulators to test M-code.
The new software will support M-code using the classified security algorithm. M-code is an updated GPS military signal that is part of the modernization of the current GPS constellation.
The CAST-MNSA is a significant addition to CAST Navigation’s suite of classified signal capabilities and is available on all of the company’s simulators. The feature will be instrumental in the effort toincorporate MNSA capability into GPS receivers. CAST provides development, integration and testing life-cycle support for the next generation of navigation systems.
“Our GNSS/INS simulators and test equipment are critical tools used to validate and verify the performance of navigation systems, and this feature ensures that our customers can keep pace with advances in technology and capability,” said Susan Gove, president and CEO of CAST Navigation.
“The classified product feature continues our 38-year history of innovation as anindustry leader whose products are critical to the support of numerous government, military, prime contractors and U.S. Department of Defense programs,” Gove said.
New hardware-in-the-loop application programming interface (API) for GNSS simulators enables greater accuracy, integrity and control for growing sensor fusion testing needs
Spirent Communications plc has released SimHIL, an integrated hardware-in-the-loop (HIL) testing software API for Spirent GNSS simulators.
SimHIL brings high-fidelity GNSS signal simulation with low latency to automotive industry HIL testbeds, the company said.

Spirent’s SimHIL software has been developed to meet the automotive industry’s growing need for realistic positioning, navigation and timing (PNT) testing for sensor fusion. As customers apply increasing pressure on car manufacturers for more advanced driver-assistance system (ADAS) features and advanced infotainment systems, test labs need to be able to combine Wi-Fi, camera, lidar, radar, inertial and GNSS data that power these advanced automotive systems.
SimHIL helps test engineers bring accurate, controlled and coherent data from GNSS and inertial sensors to their sensor-fusion algorithms within HIL test environments. Facilitating the ultra-low latency, complete control, enhanced realism, and ease of use and setup of Spirent GSS7000 and GSS9000 GNSS simulators, SimHIL is suitable for OEMs and tier-one suppliers developing ADAS, V2X and sensor-fusion engines.
The new SimHIL API enables:
external motion input – real-time direct motion and trajectory data input from simulators
sensor fusion – introducing GNSS signals into sensor-fusion engines
V2X testing – validation and performance benchmarking of V2X applications
infotainment system testing – real-time scenario feedback to system and driver responses
vehicle-in-the-loop (VIL) – final production form product testing
accurate testing – reliable results supported by ultra-low latency simulation. Criticality of ADAS features, such as lane assist and automatic braking, mean that 3+ metres of uncertainty introduced by higher latency systems is not sufficient.
“With our SimHIL software and GNSS simulators, test engineers can bring realistic, controlled GNSS simulation to their HIL testing environments – a vital requirement in a world where ADAS features are relying more heavily and critically on accurate positioning,” said Martin Foulger, general manager of Spirent’s PNT business.
Spirent has worked with leading suppliers to ensure SimHIL is compatible with their HIL platforms, and because of its open API, there’s broad scope for additional custom third-party integrations.
“When used with our GSS7000, SimHIL latency is less than 40 ms from motion command to RF output and supports all GNSS and SBAS signals,” said Ricardo Verdeguer Moreno, product manager for Connected and Autonomous Vehicles at Spirent. “SimHIL is also compatible with all the options and features available in Spirent’s GNSS simulators, including ionospheric and tropospheric modeling, antenna patterns, date and time settings, and obscuration and multipath effects via Sim3D.”
Users can easily configure and control both the GNSS scenarios, and signal generation and vehicle motion from within the HIL simulator graphical user interface — saving time and the possibility of error.
Spirent is also offering three service packages alongside SimHIL to help customers mitigate project risk and reduce the time from delivery to useful deployment.

Providing significantly improved capability, flexibility and performance, the GSS9000 Series has been updated to meet the ever more demanding test needs of high-performance satellite navigation systems.
Spirent already leads the market in multi-frequency, multi-GNSS RF constellation simulators, and the enhanced GSS9000 Series’ enriched features and capabilities raise the bar for GNSS development and test still further.

“We’re seeing the number of GNSS signals growing all the time, and an ever-increasing number of the receivers and systems we rely on every day are making use of these signals to improve accuracy, availability and continuity,” said Spirent Managing Director of Positioning, Martin Foulger. “That’s why it’s important that GNSS testing today and going forward reflects the reality of real-world situations, where simultaneous generation and testing of all signals is vital.”
The enhanced GSS9000 Series addresses this need by doubling the number of supported channels (320 in a single chassis) while maintaining its full performance specification, including in key areas such as signal iteration rate and low latency, under maximum signal dynamics.
These attributes, together with the ability to produce a comprehensive range of emulated multi-GNSS, multi-frequency RF signals, enables full and future-proofed testing of advanced applications.
“Because the GSS9000’s dedicated platform and software are designed from the ground up to work together, there is no need for a trade-off between capacity and performance,” says Foulger. “The newly-enhanced platform provides full control and verification at maximum performance across all channels at all times, removing any need for our customers to compromise their testing regimes.”
Greater signal flexibility is also built into the enhanced GSS9000 Series, through its open API and flexible system architecture. This delivers a highly-sophisticated arbitrary waveform generator (AWG) capability.
It also provides unrivalled coverage and support for all current Signal-in-Space Interface Control Documents (SIS ICDs), with even greater flexibility for both system and signal evolutions.
This includes built-in and user-defined parameter controls for generation of non-current SIS ICD PRN codes, navigation data content, navigation data rate, chipping rate, edge shaping and modulation types.
The enhanced GSS9000 Series also features sophisticated spoofing test capabilities, with full parametric control of multi-copy constellations, and trajectory spoofing/meaconing. Precise phase-aligned signal wavefront generation and multi-antenna/output capability is supported, creating the most capable anti-jam and anti-spoof test system available anywhere.
“Spirent has an unmatched pedigree in GNSS test, stretching back more than 30 years. The enhanced GSS9000 Series is the next step in the continuous advances we’ve been making over that period,” Foulger said. “Once again, we have applied our unique expertise and experience to provide those working in high-end GNSS technology and application development with an advanced test solution that meets their current and future needs.”
The enhanced GSS9000 Series will be officially unveiled at ION GNSS+ 2019 in Miami, Florida (Sept. 16 – 20).

GMV uses the flexibility of Skydel SDX to simulate GNSS timing events.
The upcoming GPS Week Number Rollover (WNRO) on April 6 is a known feature of GPS that occurs only every roughly 20 years and thus can be anticipated and tested in a receiver using a GNSS simulator.
A less-known rollover effect is also present in the Week Number (WN) associated to the UTC Offset (UTCO) transmitted by GPS. This WN has only 8 bits, which implies a range of values from 0-255, equivalent to a rollover every roughly 5 years. A possible failure in the receiver interpretation of the UTCO WN would not have such dramatic effects as a general GPS WNRO, but it could seriously affect the output of a GPS timing receiver.
Other than WN rollovers, un-programmed GNSS timing glitches are extremely rare but not impossible. A well known case is the GPS anomaly of Jan. 25-26, 2016, when around half of the satellites in the constellation transmitted an incorrect UTCO value during 12 hours. The transmitted value was of the order of 13 microseconds, when the correct value is usually of the order of just a few nanoseconds. This caused many timing receivers around the world to provide an incorrect timing information or to fail altogether.
Other fields in the GPS navigation message that could potentially be corrupt and cause incorrect timing output are Timing Group Delays (TGDs), and Leap Second information. In general, any event related to the contents of the GPS navigation message can be simulated by editing the associated bits in the message, for each satellite PRN.
However this is a cumbersome and prone-to-error task. Orolia’s Skydel SDX simulator provides an Application Programming Interface (API) that allows to develop SDX extensions to tackle particular simulation problems in an easy and flexible way.
By using this API, GMV has developed a “Time Plugin” that allows to edit directly on a user interface the numerical values associated to TGDs, UTCO, and Leap Seconds, per individual satellite PRN. These values are then converted to bits in the GPS message and transmitted in the RF stream to feed the receiver under test. Events like, for example, the GPS anomaly of Jan. 25-26, 2016, can be easily tested (as shown in the screenshot).

To create test concepts for over-the-air (OTA) antenna measurements, Rohde & Schwarz and Bluetest have integrated the R&S LBS Server, a software component running on the R&S CMW500 wideband radio communication tester, and the Bluetest over-the-air (OTA) test solution for A-GNSS systems based on Bluetest’s RTS65 reverberation chamber and Bluetest’s Flow measurement software. The R&S LBS Server controls the Rohde & Schwarz base-station simulator R&S CMW500 for LTE, WCDMA and GSM, and uses the R&S SMBV100B vector signal generator for simulation of GNSS and metropolitan beacon systems (MBS) signals. An upgrade for 5G will be available soon. The R&S LBS Server is an essential part of the R&S TS8991 OTA Performance Test System.
Brings Navsight technology to the most demanding environments

The Horizon IMU adds a third choice to SBG System’s Navsight Land/Air Solution. It is a FOG-based high-performance inertial measurement unit (IMU) designed for highly demanding surveying applications such as high-altitude data collection or mobile mapping in dense areas such as urban canyons. The Horizon IMU joins the Ekinox and Apogee IMUs as options for Navsight. The different levels of accuracy enable the solution to meet various application requirements and can be connected to various external equipment such as odometer, lidar and more. The Horizon IMU allows customers to use Navsight in high-altitude and highly dense areas, as well as where only a single antenna can be used. It is based on closed-loop FOG technology that enables ultra-low bias and noise levels. The Navsight solution can be installed in a plane or car — the sensor alignment and lever arms are automatically estimated and validated. The Navsight unit also integrates LED indicators for satellite availability, real-time kinematic (RTK) corrections and power. Qinertia post-processing software provides access to offline RTK corrections from more than 7,000 base stations in 164 countries.
The Coach 4×4 Wi-Fi/DSRC GNSS multi-band antenna enables smart grids, mobile workforce communications, and advanced automation technologies. The dual-band 802.11ac/p MIMO antenna helps boost data rates and reliability for utility networks, intelligent transportation systems and other industrial internet of things (IoT) applications. The low-profile antenna features four-port 2.4/5-GHz coverage along with PCTEL’s high-rejection GPS/GLONASS technology for network timing and tracking in a single IP67-rated housing.
Rohde & Schwarz has expanded the capabilities of its R&S SMBV100A/B GNSS simulator and R&S CMW500 LTE network simulator to operate with Vector CANoe .Car2x, a software tool for simulation, development and test of V2X-based communication applications.

The solution enables engineers to easily verify critical end-to-end safety-related V2X scenarios in a lab environment. It uses the C-V2X software package for the R&S CMW500 to simulate the physical- and MAC-layer, transmitting and receiving data over the simulated PC5 interface. This covers ideal, faded and congested channel conditions to the device under test (DUT). In its current form, the solution supports both GNSS and PSSS/SSSS sidelink synchronization options.
Rohde & Schwarz and Vector have successfully demonstrated its solution, which is designed to configure and run traffic scenarios to comprehensively test the physical layer 3GPP Rel. 14 up to the application layer of C-V2X ECUs in a lab environment.
Rohde & Schwarz is demonstrating the test solution at Mobile World Congress 2019 in Barcelona in hall 6, booth 6C40, Feb. 25-28.
The automotive industry is evolving toward connected and autonomous vehicles that offer many benefits, such as improved safety, less traffic congestion, reduced environmental impact, and lower capital expenditure. With the trend to equip vehicles with 3GPP Release 14 C-V2X ECUs, peer-to-peer data transfer in ad-hoc networks between vehicles will be realized. All vehicles share location, speed and trajectory, enabling warnings regarding on-road dangers to be shared between drivers.
Applications cover use cases such as vehicle-to-vehicle (V2V) communication, data exchange with roadway infrastructure (V2I), and interaction with vulnerable road users such as pedestrians (V2P). Data communication is implemented in the 5.8 GHz and 5.9 GHz intelligent transportation system (ITS) spectrum bands.
Traffic scenarios
CANoe .Car2x offers a range of functions designed to configure and run traffic scenarios. This allows the stimulation of a C-V2X control unit according to a defined traffic situation that tests the implemented application in a structured manner.
The included Car2x Scenario Editor supports the creation of traffic scenarios using a graphical interface. CANoe .Car2x generates the corresponding ITS communication based on the test scenario. The scenario is then played back with the R&S CMW500 providing the radio access layer with the specific physical interface. This verifies data transmission and reception over the PC5 interface so that the functions of the ECU can be tested comprehensively.
The combined solution covers all layers – the complete stack, 3GPP Radio Access Layers for C-V2X Mode 4, region specific ITS protocol layers such as EU ITS-G5 and U.S. WAVE and the ITS application message sets.
This enables testing of specific use cases such as Emergency Electronic Brake Light (EEBL), Left-Turn Assist (LTA) or Intersection Movement Assist (IMA), as well as more complex scenarios with multiple simulated vehicles such as a congested highway.
Additionally, security mechanisms could also be verified running simulations with both valid and invalid signed certificates. On top of this CANoe supports all common automotive bus connectivity such as CAN, LIN, MOST, FlexRay and Automotive Ethernet, enabling the test engineer to analyze or stimulate the ECU within an entire system from their desk.
By extending the solution with the VN4610 interface from Vector, customers can access IEEE 802.11p and CAN (FD) networks as well. This enables users to analyze and test C-V2X and IEEE 802.11p (DSRC) communication and related applications with a single setup and a common user interface.
“C-V2X device testing through the application layer is a significant step towards achieving the goal of having fully connected vehicles to improve road safety,” said Anton Messmer, vice president of Mobile Radio Testers at Rohde & Schwarz. “Our efforts in developing and verifying C-V2X end-to-end application scenarios are enabling user equipment manufacturers and OEMs to reduce the time needed to roll out C-V2X technology on a worldwide basis.”
“CANoe .Car2x has a strong focus on testing V2X based protocols and ADAS applications. This combined solution, CANoe .Car2x with the R&S CMW500, enables our customers to stimulate the V2X ECU with real scenario data in order to perform tests from physical layer up to the application,” said Stefan Krauß, director of Tools for Network and Distribution Systems at Vector. “The collaboration on this solution shows what can be achieved when leading players from the automotive and telecommunication industries work hand in hand.”

Talen-X has added the BroadSim Wavefront Simulator to its software-defined platform.
The BroadSim Wavefront further extends the capabilities achieved by BroadSim Anechoic, incorporating support for controlled radiation pattern antenna (CRPA) and multi-element receiver testing.
BroadSim, powered by Skydel SDX, has brought new innovations to the forefront each year to meet the growing needs of Talen-X’s customers, and the new wavefront simulator is the latest advancement.
Its features include:
Phase-coherent simulation
Real-time automated phase calibration
Scalable from 4 to 16 elements
Advanced jamming and spoofing scenarios.
Talen-X engineers are approaching delivery of an operational demonstration unit, as well.
BroadSense Nano
The BroadSense Nano GPS jamming sensor is the newest addition to Talen-X’s BroadSense product line. It has the smallest size, weight and power of any BroadSense product.
The video below features shows a prototype of the Nano, as well as information about its features and a demonstration of the unit reacting to various jamming waveforms in real time.
When a Pennsylvania county’s 911 system suddenly went down without warning, garbled messages across the network impacted fire and police agencies’ ability to respond to emergency messages. The issue was traced to a firmware malfunction on communications equipment, related to provision of GPS timing. The firmware had not been updated for 19-1/2 years. Why should it have been? Everything was working fine — until it didn’t.

In addition to increased jamming and spoofing threats, GPS has a “week rollover event” set to happen in April 2019. If the GPS receivers found at the heart of many critical systems do not handle this properly, any number of failures can occur.
Without GPS timing, everything slows down, has less capacity and becomes more dangerous.
This Thursday, a complimentary webinar outlines test plans for GNSS equipment used in critical timing applications, discusses the need for assured access to accurate timing across financial institutions, industrial automation, telecommunications, transportation, the power grid and elsewhere — and defines just what “assured” access means and how crucial the “assured” part is — and finally reviews some recent mishaps and near-disasters caused by interrupted or inaccurate timing.
Speaking on the 1-hour webinar are Lisa Perdue, product manager and applications engineer, Orolia; Stefania Römisch, leader, the Atomic Standards Group at the National Institute of Standards and Technology; and Dana Goward, president, Resilient Navigation and Timing Foundation.
Following each speaker’s 12- to 15-minute slide presentation, a live Q&A period with the audience will explore particular issues and concerns.
An Air Force professor was honored for years of work exploring every PNT technology imaginable in conjunction with GPS; Rockwell Collins launched a new MicroSTRIKE multi-GNSS chip for military and professional applications, available globally on a non-ITAR basis; and Spirent Federal previewed its SimMNSA, a new M-code simulation option delivering to authorized customers by the end of the year.

John Raquet, a professor in the Department of Electrical and Computer Engineering at the Air Force Institute of Technology, received the 2018 Leadership Award for Services. Raquet was recognized for work he and his team at the Autonomy & Navigation Technology (ANT) Center developed on PNT sensors and systems utilizing almost every available source, including GPS, GNSS, inertial, vision, lidar, magnetic field, pseudolites, radar, terrain mapping, signals of opportunity, star trackers, radio ranging, 3D audio, X-ray pulsars, clocks, and more.
Raquet has co-authored many defense-oriented technical papers over the past three decades. See the list at the end of this article for some of the most recent ones.
Justin Eldredge from Spirent Federal introduced Raquet and bestowed the award, after updating the audience on Spirent’s most recent advance: “This year we maintain our position of being first to market with new signals, with the launch of SimMNSA. We’re currently in the final test phase of this new M-code option and it will delivering to several authorized customers by the end of the year. If M-code signals aren’t in the spectrum of testing for you, we offer products that simulate all other GNSS signals, plus a variety of other sensors.”
SimMNSA was demo’d at the Spirent Federal Systems booth at the neighboring ION GNSS+ conference. A video presentation of SimMNSA (for Modernized Navstar Security Algorithm) is available here. Spirent’s new software will support M-code using MNSA. M-code is an updated GPS military signal that is being rolled out as part of the modernization of the current GPS constellation. Until now, AES and SDS have been the only methods authorized to be used within a GNSS simulator to produce M-code. As the long-awaited MNSA M-code signals become available, Spirent Federal Systems will make this capability available to authorized users on the GSS9000 series simulator.
ANT
After receiving the 2018 Leadership Award, Raquet spoke about his work at theAutonomy & Navigation Technology Center. “Sometimes I called the ANT the Crazy Idea Factory. We’ve tried lots and lots of things. I think I have the best job in the world, because I get to experiment with many, many things, and work with amazing people.”

“This is not the kind of community where you build something once and you’re done, you put it away. This is a growing worldwide enterprise that takes new talent to come in and fill the spots that many of the people in this room have occupied. I’m privileged to see some of the students that we’ve worked with to then go on and fill some of the gaps, really do some amazing things.”
MicroSTRIKE, a non-ITAR GPS chip
Two awards prior to Raquet’s Services award, Phil Froom from Rockwell Collins, UK, spoke about an innovative venture from Rockwell and partners QinetiQ UK as he bestowed the Satellites award.
“For many years most of you here this evening will have known Rockwell Collins as a reliable partner in the delivery of Secure (encrypted) GPS receiver, and indeed, we are still the largest producer of encrypted military GPS solutions in the world. Our partners QinetiQ also have great expertise in the design and delivery of high assurance low SWAP GPS receivers, bringing together many years of expertise of our two companies in this new venture.

“However, over the past few years we have seen our military and professional (government) users looking to greater flexibility in their use of GNSS, as new capabilities and constellations come on line. But with that flexibility, a retention of assurance and where possible, mitigation of threats. For this reason, last May, Rockwell Collins and QinetiQ signed an Alliance Agreement in London, to produce a new family of high-assurance, multi-constellation GNSS receivers for professional and military use.
“This new family of receivers is aimed to be complementary to the current encrypted family of Rockwell Collins receivers in service across the globe, but allow the customer to select his level of capability and protection based upon his operational, political or even financial needs. The new “MICRO” family of GNSS receivers will offer a multi-constellation open service (MCOS) GNSS capability, which will initially provide two receivers; the first, to be known as the Q40-MicroPNT, will address dismounted low dynamics requirements, and the second, the Q40-MicroSTRIKE, will be a gun hard, high dynamics receiver.
“You will note I said they are MCOS receivers. Therefore, they will not include an encryption device, will be Non-ITAR and will actually be produced in Europe, under the control of Rockwell Collins UK. QinetiQ are today working on the Q40 ASIC and, once available, this will be incorporated into these first two Micro Family receivers.
“These receivers will be of a common format to our existing and highly successful SAASM based MicroGRAM receivers and will offer users and OEMs the ability to select an MCOS receiver, or a SAASM (or ultimately M-Code) receiver, of a common form – factor, to meet their mission or platform needs. Thus allowing OEMs to reduce costs in integrating different form-factors, and to allow users to hold common hardware, but mounting mission specific receivers.
“We are of course extremely excited about this Alliance with QinetiQ and equally by the prospect of what it will bring to our existing and future users as we all move forward into this new era of GNSS capability.”

Skydel CEO and co-founder Stéphane Hamel discusses the company’s latest updates, which include new features for its software-defined GNSS simulator, at ION GNSS+ 2018 in Miami. Hamel also talks about a new feature to deploy the solution in anechoic chambers.
Spirent Communications plc has partnered with Fraunhofer IIS and LZE GmbH to ensure continuity of supply of Spirent’s Galileo Public Regulated Service (PRS) Radio Frequency Constellation Simulator (RFCS) product extension after the United Kingdom leaves the European Union (EU).
The new partnership will see sales and order processing hosted by LZE GmbH of Erlangen, Germany, with Munich-based Fraunhofer lIS taking on responsibility for the future development, fulfillment and support of Galileo PRS in the Spirent GSS9000 GNSS test solution.
Fraunhofer will become the sole owner of the SimPRS software/firmware, which will no longer be accessible to Spirent after the U.K. leaves the EU.
Spirent is exhibiting this week at ION GNSS+ 2018 in Miami.
This partnership and strategy is technically made possible through Spirent’s RFCS system architecture providing a clearly defined interface, with strict need-to-know separation between the core RFCS and PRS hardware and software components. This well-defined delineation ensures that both the RFCS and PRS simulation tools can be developed independently, the companies said.
“We are delighted with this new partnership with Fraunhofer and LZE,” said Martin Foulger, general manager of Spirent’s global positioning business. “We have been actively exploring contingency strategies to address the possibility that our UK-based Positioning Technology Division would be disallowed from engaging with Galileo PRS-related activities following Brexit. With this partnership in place, LZE, Fraunhofer IIS and Spirent are confident that this new approach will successfully deliver continuity of supply for Galileo PRS on the GSS9000 RFCS.”
Spirent and Fraunhofer IIS, together with key Spirent Galileo RFCS customers, can confirm that authorization was given by the relevant authorities to proceed with the partnership and that a legal framework was agreed between the two organizations.
That framework is allowing both parties to execute on a focussed technology transfer, training and quality assurance plan that will result in Fraunhofer IIS taking qualified technical ownership of the SimPRS product by the end of 2018.
The technical challenge and programmatic risks associated with this migration exercise are significantly mitigated by Spirent’s similar experience in working with a third-party U.S. entity to add GPS Modernized Navstar Security Algorithm (MNSA) support to the GSS9000.
