Test and Demonstration of the Magellan NAV PRO 5000 GPS Receiver Sub MeterSystem, July 1993

摘要

The Magellan NAV PRO 5000 GPS receiver system with Sub-Meter upgrade module wastested on the FGCS network in April of 1993. The test was designed to demonstrate two main points: the Sub-Meter capability of the Magellan NAV PRO, as well as the ability to successfully process accurate results using RINEX format data from a variety of reference stations ('base' station receivers). Three Magellan receivers acquired L1 carrier phase data in a series of 45 occupations on numerous points located on the grounds of the National Institute of Standards and Technology (NIST). Magellan's post-processing software package was employed to process RINEX data collected by 3 Trimble Navigation Systems' 4000SSE reference stations, as well as 3 Ashtech LM-XII and 2 LD-XII receivers. Please note that no least squares adjustments or other outside network adjustment programs have been applied to these coordinates. All data shown in the following tables of results were determined solely from Magellan software. Baseline results are presented for distances ranging from 111 meters to 43.8 kilometers, with an average baseline length of 21.86 km. Total root mean square (RMS) error for the entire data set was 0.87 meters, within Magellan specifications of < 1 meter RMS.
