I am attempting to identify and model the behaviour of a geostationary satellite using GMAT based on high accurate time ranging collected every two hours. GMAT is able to read the script strongly inspired from Tutorial 14 Orbit Estimation using DSN Range and Doppler Data except my GMD file only includes (Two-Way) Range information (the available data). When executing this script with GMAT R2022a (pre-compiled version for Ubuntu) I get the error message:
Utility Exception: Warning: GMAT does not support parabolic orbits in conversion from Cartesian to Keplerian state. Is this related to the lack of velocity observation? Or did I make another mistake in my processing script? I cannot find any reference to this error when searching. The "sample.gmd" is only a sample of the much larger "satre.gmd" referred to in the processing script. Thanks. _______________________________________________ GMAT-users mailing list GMAT-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gmat-users
