Precision Survey With the Ashtech XII GPS Receiver

Benjamin W. Rernondi, Javad M. Ashjaee

Abstract:	We present the first high-precision survey results using the ASHTEC XII GPS receiver. Carrier phase data have been collected since December 1987, but this paper concentrates on baseline determinations from carrier phase data collected between May and August, 1988. These baselines vary in length from the zero-length baseline to 105 km. In many cases baseline vector truth is unknown and post-processing statistics will be discussed. In those cases the rms residuals, the closeness of double-difference ambiguities to exact integers, and baseline repeatability will be emphasized. Initial kinematic survey results will be presented. Preliminary results from the FGCC tests performed August 14-18, 1988 will be presented. The Ashtech post-processing software will be included in the discussion.
