The Method For Processing Integrated Observation Data Of Geodesy In CGCS2000 Coordinate Frame

Nowdays there are mainly four kinds of space geodesy techniques:GPS,VLBI,and SLR.GPS and SLR are satellite techniques,as they can all determinate the station coordinates,ERPs and Troposphere parameters,they are necessary techniques for computing,monitoring and maintaining the ITRF.On this paper,we mainly focus on the principles and methods of GPS,VLBI,and SLR inter-technique solution combination basing on SINEX files:the GPS/VLBI/SLR multi technology integrated data processing function model and stochastic model are derived,According to the transformation formula between different coordinate frames,GPS/VLBI/SLR integrated data processing function model are deduced on three conditions;combination method of the GPS/VLBI/SLR multi technology integrated data processing and software implementation;analysis of the GPS/VLBI/SLR integrated multi technology processing data combination framework station coordinates and velocity field results and errors,comparing the earth reference with single technology with the earth reference with multi technology.The paper have established composed reference frame basing on GPS/VLBI/SLR technology,the results can be references and supplements for space geodesy data and the terrestrial frame realization and maimtainace.
