Integration of a GPS Multi-Antenna System With a CCD Camera for Rapid GIS Data Acquisition

Huangqi Sun

Abstract:	This paper presents a feasibility study of integrating a GPS multi-antenna attitude system with a CCD camera for rapid GIS data acquisition. A GPS multi-antenna system using low cost GPS receivers can replace an INS as the orientation reference while one of the GPS antennas can still be used as the position reference. The system design is discussed and the mathematical formulas specific to this problem are derived. A test was conducted using a GPS multi-antenna system and a CCD camera and the corresponding processing software was developed to process the test data. The achieved accuracy for target geodetic position is demonstrated to better than 1 meter and the accuracy of the GPS determined attitude is about 1 degree for a one meter antenna separation. The errors involved in the system are analyzed and other components of the system are discussed.
