Maneuver processing

A method of a satellite control system for solving a detected maneuver 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 exceeds a threshold number of rejected residuals;
• performing, by the processor, a smoothing operation on the recovery maneuver to compute a velocity consistency component for each direction component of the recovery maneuver in response to determining that the number of rejected residuals does not exceed a threshold number of rejected residuals;
• determining, by the processor, whether each velocity consistency component of the recovery maneuver is within a certain tolerance threshold for velocity;
• adjusting, by the processor, values of one or more velocity uncertainties associated with a velocity consistency component that is not within the certain tolerance threshold for velocity in response to determining that a velocity consistency component is not within the certain tolerance threshold for velocity;
• repeating the filtering operation by the processor;
• determining, by the processor, whether the number of rejected residuals exceeds the threshold number of rejected residuals after repeating the filtering operation;
• repeating the smoothing operation by the processor in response to determining that the number of rejected residuals does not exceed the threshold number of rejected residuals;
• determining, by the processor, whether each velocity consistency component of the recovery maneuver is within the certain tolerance threshold after repeating the smoothing operation;
• and
• reporting, by the processor, a solution to the recovery maneuver to the satellite control system in response to determining that all velocity consistency components of the recovery maneuver are acceptable after repeating the smoothing operation.
