Assured Positioning System (APS) provides positioning, navigation and timing information in environments where GPS or other GNSS is unavailable or unreliable.<\/strong> APS derives location information from ordinary communications signals transmitted from 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. <\/p>\n\n\n\n

What is Assured Positioning, Navigation and Timing (PNT)?<\/h3>\n\n\n\n

Assured positioning, navigation and timing is a broad phrase that implies GPS is unreliable and uses other technologies to provide position, navigation and timing data.  <\/p>\n\n\n\n
