Abstract:
Satellite Laser Ranging (SLR) is an extremely precise method of tracking satellites. This paper doc-uments our experiences and estimated accuracies obtained in the last 5 years while processing SLR observations of satellites in support of the Commercial Space Operations Center (ComSpOC) inter-nal calibration activities. Such precise Orbit Determination (OD) requires special algorithms and processes. To calibrate our internal sensors, we use an extended sequential filter, smoothing meth-ods, and analytic partials employed by the Orbit Determination Tool Kit (ODTK) to obtain highly accurate ephemerides. ODTK also lets us form realistic error estimates generally not obtainable via batch least squares estimation techniques. We discuss the overall setup process, and the revised set-up to update processing for the current ILRS configuration.
