Abstract: In order to properly apply transformations when using data derived from different space techniques, the corresponding frames should be clearly stated. Only then can a rigorous comparison of results be established. This ...

Abstract: Modern geodetic space techniques, such as Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging, (SLR), and Global Positioning Systems (GPS), can accurately determine the seven parameters of similarity ...

Abstract: Analysis of Global Positioning System (GPS) survey data has shown that GPS can be used to establish precise relative positioning in a three‐dimensional system. The results of many tests and operational projects have clearly ...
