发明名称 Maneuver processing
摘要 A computing device may detect that a space object has undergone a maneuver and may attempt to calculate a solution to that maneuver based in part on start and stop times and thrust uncertainties associated with the detected maneuver. However, the computing device may sometimes be unable to calculate an acceptable solution for a detected maneuver given these initial start and stop times and thrust uncertainties. Thus, the various embodiments provide for a computing device and methods implemented by a processor executing on the device for identifying and calculating a recovery maneuver of a space object when an acceptable solution for a detected maneuver cannot be determined. In the various embodiments, a computing device processor may generate a recovery maneuver based on the detected maneuver, and the processor may adjust the start and stop times and the uncertainty values of the recovery maneuver until an acceptable solution is found.

主权项 1. A method of a satellite control system for solving a detected maneuver for a satellite after entering a recovery mode, comprising: determining, by a processor of a computing device of the satellite control system, an initial start time and an initial stop time for the detected maneuver of the satellite; generating, by the processor, a recovery maneuver for the satellite based on the initial start time and the initial stop time; performing, by the processor, a filtering operation on the recovery maneuver to determine a number of rejected residuals for the recovery maneuver; determining, by the processor, whether the number of rejected residuals of the recovery maneuver exceeds a threshold number of rejected residuals; performing, by the processor, a smoothing operation on the recovery maneuver to calculate a velocity consistency component for each direction of the recover maneuver in response to determining that the number of rejected residuals of the recovery maneuver does not exceed a threshold; determining, by the processor, whether all the calculated velocity consistency components of the recovery maneuver are acceptable after performing the smoothing operation wherein all the calculated velocity consistency components are acceptable when an uncertainty value of the calculated velocity consistency components is at its minimum value; and reporting, by the processor, a solution to the recovery maneuver to the satellite control system in response to determining that all the calculated velocity consistency components of the recovery maneuver are acceptable.
