NAL Research and VectorNav Technologies are developing inertial navigation systems (INS) with Iridium satellite time and location-aiding to provide resilient assured position, navigation, and timing (APNT) services when global navigation satellite systems (GNSS) are experiencing jamming and spoofing. Plans call for the companies to co-develop solutions using VectorNav’s tactical-grade INS and NAL’s Iridium satellite time and location (STL) receivers for aerospace and military applications.
Iridium’s low-earth-orbit satellites are one thousand times stronger than traditional GNSS, meaning the STL signals can penetrate buildings and give better coverage in other GNSS-obstructed areas, according to the companies. VectorNav’s VN-210E GNSS-aided INS integrates with NAL Research’s ALTM Gen2 Mini Iridium STL receiver. “When paired, the system provides a high-rate and continuous position, velocity, and attitude solution, even in dynamic applications and in GNSS-denied environments,” the companies said.
