Adjusting a trajectory of an extraterrestrial vehicle based on an operational cycle

A trajectory determination system comprising:

• a memory that stores computer-executable instructions;
• and
• a processor in communication with the memory, wherein the computer-executable instructions, when executed by the processor, cause the processor to:
• obtain a reference trajectory for an extraterrestrial vehicle, wherein the reference trajectory begins at an initial state of the extraterrestrial vehicle and ends at a user-specified target;
• obtain a truth trajectory for the extraterrestrial vehicle that identifies estimated movement of the extraterrestrial vehicle from the initial state towards the user-specified target, wherein the truth trajectory includes an error applied to the reference trajectory and causes the extraterrestrial vehicle to end at a different target than the user-specified target;
• separate a duration of the reference trajectory into a plurality of operational cycles, wherein each of the plurality of operational cycles represent time durations in which the extraterrestrial vehicle flies a particular trajectory before updating an onboard thrust profile based on an estimate of a state of the extraterrestrial vehicle;
• obtain a thrust profile for an operational cycle of the plurality of operational cycles, wherein the thrust profile causes the extraterrestrial vehicle to reach a target position along the reference trajectory at a termination of the operational cycle;
• apply the thrust profile to the truth trajectory for the operational cycle, wherein applying the thrust profile reduces at least some movement of the extraterrestrial vehicle due to the error.
