Abstract
A system may include a global positioning system (GPS) receiver and inertial measurement units configured to generate signals representative of relative motion of the GPS receiver. The system may also include a navigation processor configured to receive a first position determination from the GPS receiver, and determine relative motion of the GPS receiver with respect to the first position determination based at least in part on signals received from the inertial measurement units. The navigation processor may also receive second respective distances between the GPS receiver and respective satellites based on signals received from the respective satellites, and determine second projected distances between the GPS receiver and the respective satellites based on the relative motion determination. The navigation processor may also select satellites from among the respective satellites for determining a second position of the GPS receiver based on a comparison of second respective distances and the second projected distances.
