Satellite orbit estimation using DORIS data: comparison of reduced-dynamic and dynamic orbit modeling and discussion of modeling aspects

Popis výsledku v původním jazyce

Reduced-dynamic orbit modeling is currently used to compute the routine solutions of the GOP analysis center, which are of similar accuracy as solutions from the other centers utilizing a precise non-conservative force modeling. GOP works with a modifiedversion of the Bernese GPS Software that has not supported non-conservative orbit modeling but utilized empirical and pseudo-stochastic orbit modeling. This limitation is now overcome by new scientific modification of the software, which opens the unique possibility to compare both approaches using the same software platform. The precise dynamic LEO orbit modeling includes the attitude models and the nominal satellite macro-models, with modeling of non-conservative acceleration, i.e., Sun radiation pressure, Earth radiation pressure and atmospheric drag. Both dynamic and reduced-dynamic approaches are used by different analysis centers providing DORIS solutions. The focus of this study is the analysis of the differences between these t
