| Abstract: | :
The orientation and scale datums of space baseline vector network established by GPS relative positioning are indirectly defined by some geometric and physical quantities as datums used for determination of the baseline vector in the positioning, and the opti mum estimates of the baselines are determined by the least squares adjustment of the network. Whereas the position datum of the network depends on the approximate value system and the method used fof the adjustment. The different definitions of position da tum of baseline vector network as well as its effects on the adjustment is discussed. And some models for transformation between different position datums are also discus sed, which would be important for the combined adjustment of satellite and terrestrial networks. |
