Space asset tracking system includes a space asset tag (SAT) disposed in a tag housing. A space vehicle tracking system (SVTS) disposed within the tag housing includes a power supply, a position sensing receiver system (PSRS), and a ground link radio frequency (GLRF) transmitter under the control of a processing circuit. The processing circuit selectively causes the GLRF transmitter to automatically transmit tracking information based on the position information. The system can also include a ground station for receiving the tracking information.

A digital image processing system reduces errors in the parameters of a sensor geometry model, through which points in a captured digital image are geolocated to the surface of the earth by means of a `real time` co-registration mechanism that refines the geometry model associated with the working image in a matter of seconds. Using a co-registration mechanism such as that described in the U.S. Pat. No. 5,550,937, the system co-registers the reduced accuracy working digital image with a reference image, geographical spatial locations of respective pixels of which have been previously determined with a high degree of accuracy. The imagery co-registration operator adjusts the respective geometry models associated with its input images, in accordance with differences in cross-correlations of the respectively different spatial resolution versions of the two images, so as to bring the respective images into effective co-registration on image registration surface. Mutual registration on the image registration surface of the working and reference images reduces the parameter errors in the original working image's sensor geometry model to the same error resolution of the reference image's geometry model.
