Abstract
Over the past decades, data recorded onboard test aircrafts has expanded much faster than downlink capacity. Given the bandwidth and power limitations, a bi-directional link appears as the best way to ensure delivery of the largest amount of relevant data per test by leveraging in-flight reconfiguration capabilities. Moreover, an uplink improves communication reliability when offering on-demand data re-transmission during the flight. Transmission capability comes with a set of constraints for the ground station that depend on communication protocols and other characteristics of the test case. In this paper, we address these challenges and compare the trade-offs and performance of several ground stations architectures using state-of-the-art components and technologies in order to achieve bi-directional communication.
