Design Document for Differential GPS (Global Positioning System) Ground Reference Station Pseudorange Correction Generation Algorithm

Abstract

The algorithms described in this report determine the differential corrections to be broadcast to users of the Global Positioning System (GPS) who require higher accuracy navigation or position information than the 30 to 100 meters that GPS normally provides. Properly equipped marine users receiving the broadcasted corrections are expected to achieve better than 10 meters accuracy with the Differential GPS system. The Differential GPS program involves the fabrication of a differential GPS testbed, consisting of an 8-channel GPS receiver for the reference station, data processing hardware and software to generate the corrections and perform channel management and integrity functions, user receiver, and data acquisition hardware and software. The system will be tested in 1987. Keywords: Kalman filtering.
