System for mapping and tracking ground targets
First Claim
1. A system for mapping and tracking ground targets of interest, comprising;
- at least one unmanned aerial vehicle, UAV and at least one Synthetic-Aperture Radar, SAR satellite in Low Earth Orbit, LEO, wherein each of the UAVs and the SAR satellites include on board sensors for acquiring imagery data for the ground target;
at least one data relay satellite in Geostationary Equatorial Orbit, GEO in operative communication with the UAVs and the SAR satellites capable of obtaining a plurality of imagery data for the ground targets and capable of sending flight path co-ordinates and the on-board sensors'"'"' pointing requirements to the UAVs and the SAR satellites; and
at least one user control center in operative communication with said data relay satellite for transmitting commands for controlling the UAVs and the SAR satellites and processing a plurality of sensory inputs received from the UAVs and the SAR satellites to map and track the ground targets,wherein said data relay satellite establishes a ground target specific communication with a user control center and its associated UAVs and SAR satellites for continuous feedback and control of the UAVs and SAR satellites for the ground target mapping and tracking irrespective of their distances from the user control center.

Abstract
A system for autonomously mapping and tracking of ground targets at a location of interest has been disclosed. The system comprises at least one user control center in operative communication with one or more data relay satellites in Geostationary Equatorial Orbit (GEO), the data relay satellites in operative communication with one or more UAVs and/or SAR satellites with on-board different imaging sensors to obtain various types of imagery data from the ground targets. The data relay satellites target specific constant communication with the user control center and the UAVs and SAR satellites for continuous feedback and control. Moreover, the system process all raw data obtained from the UAVs and SAR satellites to produce 2D and 3D Digital Elevation Models (DEMs) and high resolution images, which are displayed on the user control center and/or selected mobile handheld devices.
