DGPS ground station integrity monitoringThis paper summarizes the development of a unique Differential Global Positioning System (DGPS) ground station integrity monitor which can offer improved availability over conventional code-differential monitoring systems. This monitoring technique, called code/carrier integrity monitoring (CCIM), uses the highly stable integrated Doppler measurement to smooth the relatively noisy code-phase measurements. The pseudorange correction is therefore comprised of the integrated Doppler measurement plus the CCIM offset. The design and operational results of a DGPS ground station integrity monitor are reported. A robust integrity monitor is realized which is optimized for applications such as the Special Category I (SCAT-I) defined in the RTCA Minimum Aviation System Performance Standards.
