Abstract
Provided is a system for tracking a state of a receiver. The system receives a set of measurements collected over a period of time, indicative of a motion of the receiver. The system further processes set of measurements relating to the receiver with a probabilistic smoother to estimate a state trajectory of the receiver for the period of time, the set of measurements is associated with a probabilistic estimation model. The probabilistic smoother iteratively implements a smoothing process followed by a feedback refining process for at least some parameters of the probabilistic estimation model until a termination condition is met. The smoothing process updates the state trajectory based on the at least some parameters. The feedback refining process updates the at least some parameters to improve a metric indicative of a measurement likelihood. The system further renders the estimated state trajectory and at least some estimated model parameters.
