Geo-PNT SAASM

Master Clock + SAASM GPS Aided INS Combined in a Single Enclosure

The Geo-PNT® SAASM is an innovative and efficient solution for applications that need precise navigation data, as well as accurate time reference.  The Geo-PNT SAASM combines a high performance, versatile, GPS master clock with an accurate inertial navigation system that delivers position, navigation and timing (PNT) under all circumstances, including temporary loss of GPS, typical of dynamic platforms. The Geo-PNT SAASM minimizes size, weight and power (SWaP) due to the integration of positioning and timing that are typically achieved by two independent subsystems.
