  2. DARPA DARPA MTO MEMS Telemetered High-G Flight Test of an FPGA/PCM Encoder Recent successful testing of a Hardened Subminature Telemetry and Sensor System (HSTSS) miniature in-flight Field Programmable Gate Array (FPGA) / Pulse Code Modulation (PCM) data acquisition solution produced body-fixed ballistic measurements for a modified tank training round launched from a 120mm smooth-bore cannon in excess of 30,000 g’s with an exit muzzle velocity of 1080 m/s. The encoder was designed and manufactured at NAWC and the final board design incorporated 4 channels of signal conditioning, 8-bit analog-to-digital conversion, and power source regulation. The board was integrated within a NATO-compatible fuze volume fitted with ARL-patented optical sensors, a MEMs accelerometer, a HSTSS primary battery, and an L3 Communications transmitter/antenna package. Real-time flight tests results are shown for the August 27th, 1999 test firing at Yuma Proving Ground (YPG). P26 - 2

DARPA DARPA MTO MEMS Modified M831 Instrumented Flight Test Impact 100% operational success of an FPGA/PCM encoder-based in-flight data acquisition system during in-bore, through 30,000 g launch, and in-flight. Integration of ARL patented optical sensors and MEMS accelerometer provided body-fixed inertial and ballistic primary measurements for a modified M831.  Higher-g, higher velocity (1080 m/s) NATO-compatible fuze configuration demonstrated.  ARL rapid packaging capability demonstrated for artillery fuze applications. Advanced in-field RF data acquisition/archival solutions demonstrated with technology transfer to EC-III at YPG, AZ and Aberdeen Test Center (ATC) at APG, MD.  Navy - Best Buy Program will use five (5) NATO-compatible fuze packages for gun-launched two-stage rocket tests at Wallops Island, VA beginning December, 1999.  Recommendations: 1. Define and utilize a variety of high-g training rounds for future HSTSS tests. 2. Maintain physical properties and operational characteristics of training rounds. 3. Develop similar packaging procedures toward rapid field testing of training rounds. P26 - 12
