Interference and Multipath Effects on GPS/INS Positioning Results

摘要

This paper presents preliminary results of static andrnkinematic testing of several geodetic grade GPS receiversrnto evaluate their tracking abilities in benign andrninterference/multipath conditions. Zero and short baselinerntest results are presented, as well as kinemtaic surveyrnperformance evaluation in terms of the single differencernphase residuals and continuous kinematic RMS, and thernreceivers? ability to maintain lock to the satellites. Sevenrndifferent pairs of GPS receivers were tested, and therncommercial software, Trimble GPSurvey, was used tornprocess the test data.
