International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / 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. Specifically, GPS receivers are being
evaluated to determine their usefulness as a sensor in a Sidewinder missile telemetry
system (AN/DKT-80). 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. This concept requires a GPS
reference station to be located in the general proximity of the Telemetry data-receiving
site. 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 software
will also provide MDI information from two different airborne sources that are equipped
with GPS receivers (missile and drone). 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). A MQM-107 drone was instrumented
with the same GPS receiver, as was a ground based reference station. A simple TM was
developed for the drone that telemeters only the GPS data. The modified AN/DKT-80
system incorporated an Inertial Measurement Unit (IMU) into the design. 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. A missile firing
is scheduled for the spring of 1999 to prove this concept.
