Methods of adjusting space systems data and terrestrial measurements
- 67 Downloads
Various space systems use coordinate systems differing among each other as to coordinate origin, orientation, and scale, which brings about systematic differences between results obtained by the different techniques. A reconciliation of these differences can be achieved in a combined adjustment in which certain groups of observations are assigned transformation parameters as unknowns. This method is extended to combined adjustments of three-dimensional and terrestrial data in areas of continental extent.
