Network Telemetry: Practical Experiences and Unique FeaturesD’Amico, William P.; Stadter, Patrick A.; Lauss, Mark H.; Hooper, Andrew; Johns Hopkins University; Materiel Test Center (International Foundation for Telemetering, 2002-10)The US Army’s Yuma Proving Ground (YPG) uses a wireless local area network (WLAN) to gather test data. It is desired to extend this WLAN to support tests of gun-launched munitions where miniature and rugged data acquisition hardware will be required. The Two Way Robust Acquisition of Data (2-RAD) program has been initiated under the Central Test and Evaluation Investment Program (CTEIP) to develop a process to expand the use of WLAN technology, which is now primarily used at YPG for internal ballistic test data acquisition.
Wireless Local Area Network for Data Telemetry from Fast Moving NodesBamberger, Robert J.; Barrett, George R.; Nichols, Robert A.; Burbank, Jack L.; Lauss, Mark H.; Johns Hopkins University; U.S. Army Yuma Proving Ground (International Foundation for Telemetering, 2002-10)A Wireless Local Area Network (WLAN) based system called 2-Way Robust Acquisition of Data (2-RAD) is being developed to telemeter data from a number of fast moving airborne platforms to ground collection points distributed over a large test range. The Johns Hopkins University Applied Physics Laboratory (JHU/APL) is analyzing a 2-RAD prototype currently in operation at the U.S. Army Yuma Proving Ground (YPG) that uses an IEEE 802.11b WLAN infrastructure. Preliminary analysis efforts at JHU/APL indicate that the Doppler shift from fast movers, and the system radio link margin, do not preclude IEEE 802.11b from being used for 2 -RAD.
