Research on GPS Pseudo Range Single Point Positioning Based on Gaussian Coordinate

MENG Xiao-fang;WANG Shou-fen;Jiangsu Surveying and Mapping Product Quality Supervision and Inspection Station;Shanghai Institute of Surveying and Mapping;  
With fast and has no integer ambiguity,GPS pseudo range single point positioning has very high practical value,and the results of it can be expressed as different coordinate form.Due to the wide application of Gaussian coordinate in actual production,the method of adjustment to the Gauss plane coordinate parameter is introduced,which directly obtained Gauss plane coordinate form of pseudo range point positioning results.The corresponding mathematical model is provided,and the corresponding positioning program is compiled,and uses the broadcast ephemeris provided by IGS and the data of some station in December 2012 as the example to carry out the experiment.Finally,the accuracy of the results is analyzed and compared with the traditional coordinate transformation program based on the WGS-84 parameters.The results are satisfactory,which proves the reliability of the method.
