Abstract
According to an embodiment herein, a method of predicting a trajectory of an aerospace vehicle comprises accessing an observation of a state of the vehicle from sensor data; and using a computing system to predict different possible future positions and attitudes of the vehicle, including using the sensor data and associated latencies to determine a set of vehicle state transitions. Each state transition in the set is computed as a function of estimated latency. The method further comprises using the computing system to update a prior distribution of the vehicle state with the state transitions. Consequently, the predicted trajectory is compensated for latency.
