Abstract:	The real-time GPS correction (GPS*C) service is based on the Canadian Active Control System (CACS) network of Real-Time Active Control Points (RTACP) and a Real-Time Master Active Control Station (RTMACS). UNIX computer servers connected via land and satellite communication facilities are used for real-time GPS data acquisition and wide area GPS correction computation. The GPS*C corrections are verified at Integrity Monitoring Stations (IMS) and distributed in real-time via Virtual Active Control Points (VACP). The Real Time Application Platform (RTAP) software facilitates distributed process control, data communication, processing and distribution.
