1. A system for detection of sensor faults with regard to the automated control of a refueling boom coupled to a tanker aircraft, comprising:

  • a first GPS receiver adapted to process signals from a GPS antenna attached to the tanker aircraft, andat least one processor adapted to calculate ranges from the GPS antenna to a constellation of GPS satellites transmitting the signals being processed by the GPS receiver, the processor being further adapted to order the GPS satellites into a plurality of subsets, wherein each subset includes all GPS satellites except one such that each subset uniquely corresponds to its excepted GPS satellite, the processor being further adapted to calculate ranges between the GPS antenna and each of the GPS satellites in each subset, and wherein the processor is adapted to analyze noise characteristics associated with the ranges to determine if an excluded satellite is faulty and to calculate a GPS location for the GPS antenna based upon the calculated ranges that do not depend upon the faulty GPS satellite.
