1. A method of assessing a plausibility of a ranging measurement, comprising:
obtaining the ranging measurement from a remote device;
obtaining one or more measurements associated with the ranging measurement; and
based on the one or more measurements associated with the ranging measurement, determining the plausibility of the ranging measurement by comparing the one or more measurements associated with the ranging measurement with a model of expected values for a plausible ranging measurement;
wherein comparing the one or more measurements associated with the ranging measurement with the model of expected values for a plausible ranging measurement comprises:
projecting the one or more measurements associated with the ranging measurement into digital cells of an n-dimensional space;
determining a density of the digital cells and a global state anomaly score;
determining an anomaly score for the one or more measurements associated with the ranging measurement; and
determining the plausibility of the ranging measurement by comparing the anomaly score with the global state anomaly score.
