Spirent Federal has launched an alternative RF navigation simulator. As GPS jamming and spoofing continue to rise, interest in complementary sources of positioning, navigation and timing (PNT) data has likewise increased.
Recent government directives recommend a layered, multi-source approach, with much of the attention focused on non-GNSS radio frequency signals. These RF signals, coined alternative RF navigation, offer unique PNT capability in GPS-degraded or denied environments. The signals are secure and resilient and can act as an effective complement to GPS signals.
Spirent Federal’s product can simulate resilient alternative RF navigation signals on its own or concurrently with GNSS signals. Testing can be static or dynamic, with stationary, pedestrian and ground vehicle trajectories available.
“As a result of our extensive research and development incorporating a variety of assured PNT technologies, we’re pleased to be the first to provide this capability to our customers,” said Roger Hart, director of engineering. “Our product enables developers to test early and often, from the first stages of R&D to integration and field testing. Solutions can be tested with edge cases, hardened against interference, and deployed faster with greater confidence they will work for our warfighters.”
Spirent is actively engaged with several alternative RF navigation technologies and technology providers to incorporate signal simulation capability. To learn more, contact Spirent Federal to discuss fielded configurations.

Collaboration with Xona Space Systems
Spirent Federal Systems also announced that it is collaborating with Xona Space Systems to develop simulation and test capabilities for Xona signals produced by small satellites (smallsats) operating in low Earth orbit (LEO). Xona is a San Mateo-based startup developing a smallsat constellation for a dedicated PNT service.
Xona’s patent-pending approach using small satellites in LEO is intended to improve global PNT resilience and accuracy by both enhancing GNSS and operating as an independent system. Xona’s high-power signals utilize advanced signal structure and security techniques, improving jamming and spoofing resistance as well as multipath mitigation.
“We do all we can to protect, toughen, and augment PNT and are eager to work with emerging companies like Xona who are developing a next-gen navigation and timing architecture,” said Jennifer Smith, senior director of Business Development at Spirent Federal. “Our simulators provide critical support to developers and integrators by enabling testing and validation before the product deploys.”
The space and defense sectors also benefit from Spirent Federal’s expertise in generating high fidelity RF signals using quadrature (I/Q) data. Spirent test tools allow the full customization of I/Q data. Customers can generate unique I/Q data corresponding to experimental modulation schemes and use Spirent Federal’s signal generation capabilities to create the corresponding RF. Such rapid prototyping allows for quick turnaround times and shorter iteration cycles.
Alternatively, scenarios created using Spirent Federal’s proprietary SimGEN software can be saved as I/Q data which can be processed by software-implemented receivers.
“Building a new generation of satellite navigation and timing services goes far beyond just the satellites,” said Brian Manning, CEO of Xona Space Systems. “It requires building an entire ecosystem from ground stations to chipset manufacturers to end users and systems integrators. Having reliable and trusted simulation capabilities is critical to support all of these areas which is why we are thrilled to be working with Spirent to provide a robust solution to our partners.”

New SA65 CSAC provides wider operating temperatures, faster warm-up and improved frequency stability in extreme environments
Photo: Microchip Technology
Microchip Technology Inc. is offering the new SA65 chip-scale atomic clock (CSAC), providing precise timing accuracy and stability in extreme environments. Designed for military and industrial systems, the Microchip’s SA65 CSAC features ultra-high precision and low power consumption
Advanced military platforms, ocean-bottom survey systems and remote-sensing applications all require precise timing. CSACs ensure stable and accurate timing even when GNSS time signals are unavailable, thereby helping industrial and military system designers to meet timing requirements.
Microchip’s SA65 CSAC is an embedded timing solution with improved environmental ruggedness, delivering higher performance than the previous SA.45s CSAC, including double the frequency stability over a wider temperature range and faster warm-up from cold temperatures. The SA65 has an operating temperature range of –40 to 80 °C and a storage temperature range of –55 to 105 °C. The warm-up time of two minutes at –40 °C is 33% faster than that of the SA.45s.
These performance improvements benefit designers of highly portable solutions for military applications such as assured positioning, navigation and timing (A-PNT) and C5ISR (command, control, communications, computers, cyber, intelligence, surveillance and reconnaissance). It meets precise frequency requirements of a low size, weight and power (SWaP) atomic clock. Improvements such as fast warm-up to frequency after cold start, temperature stability over a wide operating range, and frequency accuracy and stability enabling extended operation while GNSS is denied help to ensure mission success in conflict environments.
The SA65 CSAC provides precise timing for portable and battery-powered applications requiring continuous operation and holdover in GNSS-denied environments. The SA65 is form-, fit- and function-compatible with the SA.45s, which minimizes risk and redesign costs for the system developer while improving performance and environmental insensitivity.

It features multi-band, multi-constellation GNSS receivers and supports multiple PTP profiles, including substation power and core telecom backup sync, while also allowing conversion between them and supporting legacy interfaces.
The products are part of ADVA’s new aPNT platform, integrating threat detection, multi-source backup and ADVA’s intelligent Ensemble Sync Director.
How will widespread deployment of 5G most benefit GNSS?
Greg Turetsky
“The connectivity options that widespread 5G offer will accelerate multiple GNSS benefits. The high bandwidth is starting to encourage many into the RTK domain, but I think the bigger opportunity may come from the low power versions that enable IoT applications. The combination of the ubiquity of cellular connectivity with the low power of NB-IoT could truly accelerate the real time asset management sector all the way down to the package/pallet level.” — Greg Turetzky
Allison Brown
“Widespread deployment and adoption of 5G is likely to continue to increase the demand for spectrum as broadband access continues to expand. The recent FCC decision allowing Ligado to operate terrestrial networks in bands near GPS is likely not the last decision that will result from this increasing demand. It is not clear to me that 5G deployment will ‘benefit’ GNSS and chipset vendors may need to prioritize developing products that have improved robustness in the presence of nearby interference.” — Alison Brown
Miguel Amor
“The benefit of 5G will be seen in the long term, when 5G ranging capability is available. Hybrid positioning algorithms using both 5G and GNSS observations will provide significant positioning benefits in challenging urban environments and seamless navigation between indoor and outdoor environments. Applications across markets will see the benefits of hybrid 5G and GNSS navigation, but the real advantage lies in how this hybrid will enable the future of autonomous mobility. We will see both technologies working closer together to deliver a seamless and ubiquitous positioning solution.” — Miguel Amor
Mitch Narins
“Like communications, the ability to precisely and securely position and navigate is an essential part of 21st century life. Together they must support both critical and non-critical operations. This requires finding a common understanding of spectrum needs and how to have the best of both. In the long run, end runs by either side may achieve myopic goals but will damage society. The problem is crying out for an enterprise-level systems engineering leadership that can plot our future spectrum course. Else, the push for spectrum will continue, fueled by ‘entrepreneurial spirit’ and often a lack of understanding of the importance of other spectrum uses.” — Mitch Narins

Additional Loyal Wingman jet-powered drones are being developed. Plus, quadcopters are helping calibrate and maintain aviation ground navigation systems.
I’ve previously discussed the Loyal Wingman project. Companies in the United States and Australia are developing unmanned full-scale jet-powered drones t0 fly alongside frontline fighters, and perhaps take on riskier missions.
The Loyal Wingman drones are powered with artificial intelligence developed for the U.S. Air Force Skyborg program.
Programs in other parts of the world are also developing technology for the same fly-along objectives. The United Kingdom has launched the Lightweight Affordable Novel Combat Aircraft (LANCA) program, and India is working on the Combat Air Teaming System (CATS) Warrior project.
UK LANCA project
The UK usually takes its time progressing with new aviation concepts, but has now awarded a £30 million concept contract to Spirit Aerosystems in Belfast to develop and fly a demonstrator drone by the end of 2023.
Meanwhile, Kratos in the United States and Boeing Australia both have Loyal Wingman UAVs well into flight test programs as part of the Skyborg program. (The first test flight of the Loyal Wingman was successfully completed in February.) Nevertheless, the LANCA schedule should mesh with that of the UK’s next-generation fighter program, known as Tempest, which is just getting started.

Spirit Belfast is the Irish subsidiary of Spirit AeroSystems (Wichita, Kansas), previously owned by Bombardier (Montreal, Canada) and, before that, Shorts Brothers, Belfast. Spirit was previously involved in manufacturing aerostructures and will apply its unique composite resin transfer-infusion technology to build a high-speed capable, lightweight fuselage for the aircraft.
Spirit has formed Team Mosquito, joining Northrop Grumman UK and Intrepid Minds for flight controls and avionics. An engine supplier and developer has yet to be announced.
CATS Warrior project
On the other side of the world, Indian state-owned Hindustan Aeronautics Limited (HAL) has apparently invested significantly since at least 2019 in a program to develop another Loyal Wingman concept, known as the HAL Combat Teaming System Warrior (HAL CATS Warrior). A mockup of the CATS Warrior was on display at Aero India 2021.
While still in the early phase of development, the program appears to be well into the major undertaking by HAL and its partner Newspace R&D. HAL has been the indigenous aircraft manufacturer for the Indian Air Force since the late 1940s, with facilities in Bangalore and with more than 25,000 employees.
The design goals for the Warrior drone appear to mirror those of the programs in the United States and the United Kingdom — to create an independent, autonomous, unmanned vehicle that can be teamed alongside frontline fighter aircraft as an expendable force multiplier.
Flight inspection drones
While we’re on the topic of aviation, let’s pull back to more current unmanned applications. News has emerged of a drone being used to inspect a landing-aid system in Russia. Aviation authorities in many countries spend lots of time and money on verifying and calibrating new and existing ground-based landing and navigation aids, to the point of equipping general aviation aircraft with extensive instrumentation and dedicating them to regularly checking key airport and en-route systems.
This is an expensive and lengthy task — all the way from buying, maintaining and operating aircraft to equipping each flying laboratory and maintaining complex onboard equipment, as well as training and employing skilled pilots and equipment operators.

Cursir in Russia has installed a specialized radio receiver on a commercial drone and used it to pre-configure a newly installed instrument landing system (ILS) at the Ulyanovsk-Vostochny airport, where difficult terrain makes the initial set-up of the ILS quite complex.
However, by using this calibration drone, set-up time was significantly reduced and adequate preparations were made for subsequent control flights by a fully equipped flight inspection aircraft. Even though these formal flights were still required, calibration of the ILS was less involved and fewer flights were necessary.
In the future, maintenance checks using only the calibration drone may be possible. Drones have also been in use for complete NAVAID inspection for some time, with companies including Canard in Spain and Colibrex in Germany.
Canard’s drones undertake flight inspection of runway lighting, ILS and other airport NAVAIDS. It uses a database of airports, runways and systems for flight planning, autonomous drone operations and analysis/reporting of collected data. Canard was founded in 2015, and its first flight inspection contract was in 2017 for seven European airports.

Colibrex built its own COL-X8 NavAidDrone in order to better integrate its in-house flight inspection receivers and antennas. The requirement for flight inspection is to accurately evaluate the signal-in-space being transmitted by the NAVAID, so Colibrex invested heavily in the development of its on-board RF reception and in-house results analysis systems. Early trials were first run in 2012, through many different measurement campaigns around the world; Colibrex has now established an extensive drone flight inspection capability.

To sum up, more Loyal Wingman jet-powered drones are in development, and perhaps we now have a little insight into how quadcopters are being used to calibrate and maintain aviation ground navigation systems. These are just a couple more innovative applications for unmanned aircraft.
SkyTraq Technology Inc. has launched a GNSS/inertial measurement unit (IMU) suitable for both automotive pre-installation and aftermarket.
The robust PX1120D dead-reckoning module integrates a 6-axis IMU and a concurrent quad-GNSS chipset, forming a sensor-fusion solution that maximizes positioning accuracy even in challenging environments. The PX1120D receives concurrent GPS/GLONASS/Galileo/Beidou/QZSS signals.
For automotive pre-installation applications where vehicle wheel-tick signals are available, the PX1120D provides wheel-tick sensor fusion with automotive dead-reckoning. In aftermarket applications where wheel-tick signals are unavailable, the PX1120D provides an untethered dead-reckoning sensor-fusion solution.
A single PX1120D module provides both automotive and untethered dead-reckoning functionality, simplifying logistics. The PX1120D provides 100% position coverage. It is suitable for infotainment systems, telematics control units, vehicle tracking, and advanced driver-assistance systems (ADAS) applications that require the highest performance and reliability, as well as uninterrupted positioning.
The PX1120D supports flexible mounting in any orientation. Its auto-calibration feature simplifies the installation procedure.
The 12 x 16 mm PX1120D offers continuous navigation in tunnels and underground parking lots. It can output attitude, gyroscope and accelerometer sensor data, making it useful for black-box driver behavior monitoring and insurance accident reconstruction.
The PX1120D uses an AEC-Q100 qualified chipset and is manufactured in ISO/TS-16949 certified plants. An engineering sample, evaluation kit and datasheet will be available by the end of August. Volume delivery to customers begins in the fourth quarter of this year.

The Qualcomm Flight RB5 5G Platform’s high-performance and heterogeneous computing at ultra-low power consumption provides power efficient inferencing at the edge for AI and machine learning (ML), enabling fully autonomous drones, the company said. New camera capabilities deliver premium image capabilities and performance.
With 5G and Wi-Fi 6 connectivity, this platform enhances critical flying abilities beyond visual line-of-sight (BVLOS) to support safer, more reliable flight. In addition, safety controls alone can no longer assure industrial and commercial drone safety, especially when scaling to Beyond Visual Line of Sight operations.
The Qualcomm Flight RB5 5G platform is equipped with a Qualcomm Secure Processing Unit to support modern drone demands for cybersecurity protections as a key enabler of data-protection and safety requirements.
Partners. Qualcomm Technologies is working with Verizon to complete network testing of the Qualcomm Flight RB5 5G Platform for the Verizon 5G network, and expects the platform, which is 5G mmWave capable, will be offered via the Verizon Thingspace Marketplace.
The Qualcomm Flight RB5 5G drone reference design is available now for pre-sale through ModalAI. A development kit is expected to be available this year in the fourth quarter.
“We have continued to engage many leading drone companies, enabling 200+ global robotics and drone ecosystem members in addition to consistently driving and promoting worldwide drone standardization and transformative 5G capabilities in organizations such as 3GPP, GSMA, the Global UTM Alliance, the Aerial Connectivity Joint Initiative (ACJA) and ASTM,” said Dev Singh, senior director, Qualcomm Technologies.
