METHOD TO HANDLE SINGLE FAILURE GPS FAULTS IN HIGH INTEGRITY RELATIVE POSITIONING SYSTEMS

摘要

A method and system to handle single failure GPS faults in high integrity relative positioning systems is provided. The system is configured to receive a number of reference measurements in carrier-phase real time kinetic positioning systems and identify if a single fault exists. The system identifies the type of fault and mitigates the effects of the single fault to provide a positioning system with a high integrity that is suitable for applications involving risk to human lives.
