System and method for angles-only position and velocity determination using closed-form triangulation

Patent image
NRL

Methods and systems are presented for determining position and velocity information using angles-only measurements for a moving observer in a three-dimensional space, in which three or more observations are obtained by the observer of objects with known positions, line of position vectors are generated which correspond to the individual observations, and position and velocity vectors for a chosen time are determined using a closed-form least-squares minimization over the Euclidian distances between each line of position vector and the observer's estimated position at the time of the observation.
