Test and Demonstration of the Wild GPS-System 200 Surveying System: June 1992

摘要

The Federal Geodetic Control Subcommittee (FGCS) tested and evaluated the WILDGPS-System 200 surveying system and associated receiver processing software, in June, 1992. The dual frequency receivers were tested in several independent operational tests: static, rapid static, reoccupation (pseudo-kinematic), and stop-and-go kinematic. The post-processing software, SKI, was employed to process data in the field using the predicted broadcast ephemerides. Results, presented in the form of repeat vectors and adjustment errors, are compared with FGCS geometric accuracy standards and specifications for GPS relative positioning. Baselines varied in length from 183 m to 108 km. Overall, the results from the use of the predicted emphemeris in the solutions indicate that the WILD GPS-System 200 Surveying System will yield accuracies that meet or exceed the vendors' specifications.
