Autonomous Dynamic Data Sensor (ADDS)


NASA Langley Research Center (LaRC), Johnson Space Center (JSC), and Jet Propulsion Laboratory (JPL) contracted Invocon to develop a system to perform experimental data gathering and recording of environments on and around on-orbit vehicles. The goal of ADDS was to test low power, high accuracy, low mass sensors on orbit prior to the Shuttle/Mir RME on STS-86. The data was used to evaluate the effects of external environment on structures and flight dynamics on STS-80 in 1996.

ADDS instrumented three sensors: Accelerometer (100Hz), Pressure (1100Hz), and Heat Flux (1100Hz).

The ADDS was a prototype version of the Wireless Data Acquisition System (WDAS) system that flew twice on the Shuttle in 1997.
