Abstract

For its synergistic relationship, the integrated GPS/INS system has been adopted in many navigation systems. In this paper, a complete GPS/INS integration technique utilizing GPS carrier phase measurements is proposed. A measurement model of double-differenced GPS carrier phase measurements is newly derived in order to be used with the INS error model. Also, an algorithm is suggested to resolve the integer ambiguities of GPS carrier phase measurements by employing MS information. From simulation results, performance of the suggested technique is verified
