Assured Positioning System (APS) provides positioning, navigation and timing information in environments where GPS or other GNSS is unavailable or unreliable. APS derives location information from ordinary communications signals transmitted from Globalstar low-Earth-orbit (LEO) satellites. These signals-of-opportunity (SoOP) are not special position/navigation signals and are not subject to GPS/GNSS jamming or spoofing. For dismount applications, SoOP technology can be combined with IMU and barometric sensor inputs. In addition, APS is provided as a plug-in to the Android Team Awareness Kit (ATAK) residing on a user smartphone.
In addition, APS can be implemented on ER310. ER310 is our flexible, high-performance, handheld platform designed to host and execute challenging RF applications with demanding real-time processing and communications requirements. ER310 supports a wide scope of missions, including assured PNT (Positioning, Navigation and Timing).
