Global Navigation Satellite Systems Engineering, Policy, and Design
VectorNav Technologies, a provider of high-performance, low-SWaP IMU and GNSS-Aided Inertial Navigation Systems, recently participated in the USAF’s NAVFEST 2024 Test Event. The event, hosted by the 746th Test Squadron at Holloman Air Force Base, New Mexico, and held at White Sands Missile Range (WSMR), took place from May 6-17.

For applications that require accurate UTC timing, the options are pretty limited. Yes, GPS provides timing, but it has its vulnerabilities. Iridium STL is the only other option with global coverage, but it has its drawbacks, too, as it’s restricted to L1 and can’t be leveraged for every application.

Silicon Sensing is to open its first US office, with a dedicated in-country team lead by the new head of sales – Americas, Kevin Swain. This new facility will help ensure the company efficiently supports the growing demand for their rugged, high performance inertial products across North and South America.

The Grimaldi Satellite Autonomous Berthing (GSAB) project, funded by the European Space Agency’s NAVISP program, has developed a system enabling automatic, high-precision port berthing operations in large (200m) carrier ships. The system provides ships’ captains and crew with an overview of ship conditions in real time in port settings, including detailed information on maneuvering operations to be performed.

It has been widely demonstrated that GNSS-based localization technologies are vulnerable to signal jamming and spoofing/replay attacks, where a receiver can be either denied positioning or deceived to compute a forged PVT solution. Today, it is possible to spoof a GNSS receiver to any arbitrary location and time in the world with many incidents being reported in the wild.

Iridium recently announced its newly acquired Iridium Satellite Time and Location (STL) service will provide resilient timing synchronization to FAA data center facilities across the U.S. Through a five-year contract with L3Harris Technologies, the global voice and data satellite communications provider will make the service available to more than three dozen L3Harris-operated communications network backbone nodes and a similar number of FAA facilities.

The advantage of incorporating 5G within a global positioning solution lies in its extensive coverage and accessibility, especially in urban areas, where GNSS signal quality can be significantly compromised.
