Application of a satellite communication and location system for bomb damage assessment
The Global Verification and Location System (GVLS) is a satellite based communication package proposed for the Global Positioning System (GPS) Block IIR satellites. This system provides the capability to relay bursts of information from small, low power mobile transmitters to command and control facilities. Communication paths through multiple GPS satellites within the field of view allow location of the transmitter using time difference of arrival (TDOA) techniques. Alternately, the transmitter can transmit its own location if known by various other means. Intended applications include determination of the status and location of high-valued assets such as shipments of proliferation-sensitive nuclear materials and treaty-limited items or downed air crews and special operations forces in need of extraction from hostile territory. GVLS provides an enabling technology which can be applied to weapon impact location. The remote transmitter is small and light enough to be integrated into a weapon delivery vehicle, such as a cruise missile, and requires power only during the last second of flight. The antenna is a conformal patch design, therefore minimizing aerodynamic considerations. Precise impact locations are determined by the GVLS system and can be communicated to responsible commands in near real time allowing rapid bomb damage assessment and retargeting without the typical delays of overhead reconnaissance. Since burst data communication is used, weapon status immediately prior to impact can be transmitted providing knowledge of proper arming sequence and other pertinent information. If desired, periodic bursts can be transmitted while in flight, enabling in-course tracking of the weapon. If fully deployed, the GVLS system would consist of communication relays on 24 GPS satellites, five ground stations deployed worldwide, and portable base stations for authorized users to receive and display locations and contents of their transmissions.
