  • Apparatus and method for using GPS aboard satellites
    Publication number: 20020072852
    Abstract: An apparatus and method for using GPS uses a radiation tolerant executive module to monitor and reinitialize a GPS module. The GPS module can reload information from a radiation tolerant memory when it is reinitialized. The radiation tolerant executive module also can direct a first GPS module having a first clock generator and a second GPS module having a second clock generator to use a clock signal from one of the first clock generator and the second clock generator. The radiation tolerant executive module also may be used to direct a first GPS module having a first clock generator and a second GPS module having a second clock generator to phase lock the first clock generator to the second clock generator.
