PPS Positioning in Weak Signal GPS Environments Using a TIDGET Sensor

This paper describes a GPS tracking solution that collects GPS broadband snapshots using NAVSYS' patented TIDGET ("Tracking widget") sensor technology and post processes these snapshots to create a Precise Positioning System (PPS) solution using a SAASM receiver. This approach has the advantages of reducing the size, weight, cost and power of the electronics in the sensor while still producing SAASM-based solutions for military tracking applications. This paper presents test results of this TIDGET-SAASM architecture showing its operation in normal and degraded GPS environments.
