The Space Shuttle is able to receive position information from the GPS network via on-board GPS receivers. Currently, the GPS operation for the Shuttle is not very accurately modeled, GPS is assumed to be an 'always on' device characterized by a constant figure of merit, which is then used to limit the position and velocity errors in the propagated state vector. | The Space Shuttle is able to receive position information from the GPS network via on-board GPS receivers.
