COMPLEMENTARY PNT / Orolia 5G Promises Deeper Connections answers by Erik Oehler MARKETING DIRECTOR What are some of the most promising approaches to complementary PNT and how does simulation technology help? 5G is the most promising for the future. I believe the benefits in infrastructure, speed, precision, reliability, and the industry incentives 5G offer are superior to GNSS. Alternative signals of opportunity and new commercial satellite-based providers are always valuable as extra layers of resilience. However, PNT from 5G is not quite ready yet. There will be a transition period during which systems use GNSS and these signals of opportunity simultaneously, so simulation enables receivers of any complementary signal to be tested in the same environments and with the same potential threats faced by primary constellation signals. leaders such as Meta on building a better PCIe Time Card. We offer edge time servers with the ability to automatically add Hoptroff’s Traceable Time as a Service. If 5G PNT becomes a standard, we are already providing industry leaders such as Anritsu with solutions for acceptance testing on a major carrier’s backbone. With our pending acquisition by Safran and access to a world-leading portfolio of INS components, we are one of the most qualified companies in the world to solve nearly any PNT challenge. What kinds of complementary PNT are most useful in addressing specifically the challenges posed by jamming and spoofing, and how does simulation help? In two technical notes published by NIST, they recognize STL as one of four recommended solutions for PNT resilience and Orolia has the most atomic clocks in orbit, including those the only one being both independent of GNSS and capable aboard the Galileo constellation. We integrate anti-jam of sub-microsecond accuracy. Being closer to Earth, it is antennas and build Interference Detection and Mitigation a stronger signal, making it 1,000 times less susceptible to (IDM) into our products. We partner with companies that jamming. Additionally, because it is encrypted it is inherently offer alternative signals, such as STL from Satelles. Our immune to spoofing. The aforementioned Hoptroff TTaS is SecureSync NTP and PTP time servers live in the world’s time delivered over VPN, removing the outside environment biggest data centers and support encrypted signals, such as component completely. For positioning and navigation, the M and Y code for our militaries. We innovate with industry integration of an IMU provides a contiguous PNT solution even during periods of GNSS denial, analogous to how an atomic clock provides precise time holdover during these denial periods. Combined with anti-jam antenna technology and IDM software, a robust PNT solution is always available. Simulation helps by (1) identifying the vulnerabilities your PNT system might have (or could have in the future to evolving threats) and (2) verifying the total integrated resilient system. Our GSG-8 Advanced GNSS Simulator supports hundreds of GNSS full spectrum signals, custom signals, and hardware-in-the-loop testing of integrated IMUs at up to 1000 Hz iteration rate. Our Skydel Wavefront and Anechoic simulators a can verify the most complex GNSS anti-jam antenna systems. OROLIA DEVELOPED THE SKYDEL GSG-8, a PNT test solution in its GSG family of simulators, to deliver GNSS signal testing and sensor simulation performance in an easy to use, upgradable and scalable platform.
