DESIGN AND UPGRADE OF A COTS RECEIVER/COMBINER SYSTEM TO MEET NASA’S LEO-T PERFORMANCE REQUIREMENTS

Abstract

The new NASA LEO-T (Low-Earth Orbite Ground Systems) satellite systems requires a wide range of data rates including extra wide-band requirements with near theoretical performance standards. This paper describes new design implementations incorporated into a COTS (Commercial Off-The-Shelf) Telemetry Receiver and Combiner System redesigned to meet the new wide band data requirements for NASA’s LEO-T satellite down link telemetry data requirement. The paper will also provide performance data showing system performance for the high data rates.
