Analysis of Candidate Communication Architectures for TAMDAR Implementation in 2007-2015

摘要

The Johns Hopkins University Applied Physics Laboratory (APL) is conducting communications architecture, systems engineering, and modeling/simulation work in collaboration with the NASA Glenn Research Center (GRC) and supporting contractors. This paper is focused on analyzing the suitability of data link technologies that might support the distribution of information from aircraft equipped with the Tropospheric Airborne Meteorological Data Reporting (TAMDAR) system. TAMDAR 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 regionally based and General Aviation (GA) aircraft, augmenting current meteorological observations, especially at lower altitudes and during off-peak times. The paper describes TAMDAR requirements, and then presents the results of a survey of current and potential future communication systems in an effort to determine which systems might support a TAMDAR system in the 2007-2015 time frame.
