The development of an experimental Health Monitoring Unit (HMU) for GPS (Global Positioning System) and GLONASS (Russian GPS) is reported. The purpose of the HMU is to provide timely warnings to the navigation users of the satellite navigation systems if the satellite navigation systems are not used for navigation. The monitoring unit is a key element in the integrity channel concept of a civil overlay NAVSAT to GPS and GLONASS. The most stringent requirements are those of civil aviation: in the nonprecision approach phase horizontal position errors exceeding the 600 m SPE thereshold have to be reported within 10 seconds. The concept of the HMU is to use a GPS receiver as well as a GLONASS receiver in a known location in order to detect large pseudorange errors and to identify the malfunctioning satellites. This means that the station is able to work autonomously. It will also provide pseudorange errors compatible with the American RTCA SC-159 approach and for a future wide area DGPS (Differential GPS) system.
