Differential GPS for fleet base stations with vector processing mechanization

摘要: A fleet management system for a base station to obtain differential GPS corrections the location information vehicles. vehicle first sends of "position solution" back with time annotation, where position solution only needs specify position, velocity and satellites observed. The station, which already has an priori fixed vector its location, generates potential set all possibly observable satellites. This allows vector-process determine correction each combinatorial observed by vehicle. way, equivalent accuracy 10 meters or better can be achieved without imposing communications burden system.
