Development of a real-time kinematic GPS system: Design, performance and results.

摘要

A real-time kinematic GPS system has been developed which achieves decimetre (with a floating ambiguity solution) and centimetre (with a fixed integer ambiguity solution) accuracies in real-time at a 1 Hz update rate. Based on a double difference floating ambiguity algorithm and a fast integer ambiguity search filter (FASF), the system resolves integer ambiguities if possible, or otherwise uses a floating ambiguity solution. The system integrates two L1 C/A code NovAtel GPSCard
