Simultaneous Observations of Global Positioning System (GPS) Satellites with Two NAVSTAR Geodetic Receiver Systems (NGRSs)

摘要

Two conventional code tracking Global Positioning System (GPS) receiver systems were used to simultaneously track GPS satellites on a short baseline. Six-second pseudorange observations and range differences from 1-min Doppler counts at a single frequency were obtained from each receiver. Relative positioning of the receiver antennas was conducted over zero-length and 2-m baselines. Common and independent frequency standards were used on different days; the results were compared.
