More Information
Summary:The invention relates to a threshold determining apparatus, method, and procedure, used for selecting ephemeris data sent by the GPS satellite among several GPS satellites and making sure that the threshold determining apparatus of the GPS satellite upon the detecting position can obtain the threshold capable of meeting the integrity and sustainability of the position-detecting system. The threshold determining part, based on the maximum allowed detecting probability of failure and the maximum allowed fault alarm probability, is used for selecting the threshold of the GPS satellite. As it is based on the maximum allowed detecting probability of failure, the integrity of the position-detecting system can be satisfied. As it is based on the maximum allowed fault alarm probability, the sustainability of the position-detecting system can be satisfied.
