Abstract: | Gravity field determination using the measurements of Global Positioning receivers onboard low Earth orbiters and inter-satellite
measurements in a constellation of satellites is a generalized orbit determination problem involving all satellites of the
constellation. The celestial mechanics approach (CMA) is comprehensive in the sense that it encompasses many different methods
currently in use, in particular so-called short-arc methods, reduced-dynamic methods, and pure dynamic methods. The method
is very flexible because the actual solution type may be selected just prior to the combination of the satellite-, arc- and
technique-specific normal equation systems. It is thus possible to generate ensembles of substantially different solutions—essentially
at the cost of generating one particular solution. The article outlines the general aspects of orbit and gravity field determination.
Then the focus is put on the particularities of the CMA, in particular on the way to use accelerometer data and the statistical
information associated with it. |
