Abstract
Abstract A portable target locator system capable of being transported and utilized by an individual combatant is disclosed. The portable target locator system comprises a rifle-like target locator and a transmitter/modem capable of transmitting target location coordinates to a weapons delivery system. The rifle-target locator preferably includes a Global Positioning System (GPS) receiver capable of determining the location coordinates of the target locator automatically and with a high degree of accuracy from signals transmitted from a network of orbiting satellites. A laser rangefinder and digital azimuth and inclination sensor are then utilized to accurately determine the range, azimuth and inclination of an identified target from the target locator. This information is then processed in conjunction with the location coordinates of the target locator to generate location coordinates for the selected target. The target location coordinates are then coupled to the transmitter/modem for transmittal to a remotely located control system, such as a weapons delivery system. In one preferred embodiment of the present invention a non-volatile memory is provided and multiple target coordinate sets are then stored within the memory and subsequently transmitted to the weapons delivery system during a single transmission.
