WINCOMM UAT Laboratory Test Activities

摘要

The Johns Hopkins University Applied Physics Laboratory (APL) has performed systems engineering and architecture definition for the NASA WINCOMM program to support data transfer of on-board aircraft weather sensor data and dissemination of weather information to aircraft in collaboration with the NASA Glenn Research Center (GRC). The Tropospheric Airborne Meteorological Data Reporting (TAMDAR) system is designed to collect meteorological data onboard aircraft in flight and broadcast the data to ground systems and airborne users primarily in an attempt to improve the data used in forecasting models and to provide real-time hazard alerts. The TAMDAR system is being targeted for deployment on General Aviation (GA) aircraft, which will augment current meteorological observations, especially at lower altitudes and during off-peak times. This work has identified the changes necessary to avionics and ground infrastructure equipment operating on the Universal Access Transceiver (UAT) datalink to support this data transfer and dissemination. This paper details the architecture implemented, message types and formats as well as the system data flow. Additionally, the changes implemented to the ADS-B equipment will be discussed along with the testing methodology used to validate the architecture.
