Abstract :
It is shown that dilution of precision terms for relative positioning, using double-difference processing of Global Positioning System (GPS) satellite signals, are bounded by the corresponding dilution of precision terns for point positioning. This result is valid for the case of four satellites, with a common reference satellite.
