![]() ![]() These targets are controlled by the Army Ground Aerial Target Control Systems (AGATCS) and are recoverable via parachute if not shot down. ![]() The MQM-178A (Firejet) is a pneumatically launched target capable of speeds up to 400 mph at altitudes up to 35,000 feet. Current HSATs are: MQM-107 Streaker, BQM-34 Firebee, and MQM-178A Firejet. A missile firing is scheduled for the spring of 1999 to prove this concept.Aerial Targets’ mission is accomplished by two major target categories: High Speed Aerial Targets (HSAT) and Medium Speed Aerial Targets (MSAT). Post processing software was developed that will integrate the IMU information with the GPS data so accurate position can be generated if the GPS data was momentarily lost. The modified AN/DKT-80 system incorporated an Inertial Measurement Unit (IMU) into the design. A simple TM was developed for the drone that telemeters only the GPS data. A MQM-107 drone was instrumented with the same GPS receiver, as was a ground based reference station. To prove out this concept, a Commercial Off the Shelf (COTS) Commercially/Available (C/A) code GPS receiver was integrated into the AN/DKT-80 Sidewinder telemetry system (TM). ![]() This software will also provide MDI information from two different airborne sources that are equipped with GPS receivers (missile and drone). Software has been developed that will compare GPS data from the airborne telemetry system to the GPS reference station and display a real-time TSPI solution. This concept requires a GPS reference station to be located in the general proximity of the Telemetry data-receiving site. Initial testing has indicated that position information generated from a GPS receiver can provide significantly better position data than a radar tracking system when using Double Differential error correction techniques. Specifically, GPS receivers are being evaluated to determine their usefulness as a sensor in a Sidewinder missile telemetry system (AN/DKT-80). Abstract The use of Global Positioning System (GPS) receivers as a source to provide Time Space and Position Information (TSPI), and Miss Distance Indication (MDI) data in Test and Evaluation (T&E) applications is being considered. ![]()
