Electronic Systems Test Laboratory

    Electronic Systems Test Laboratory

    The Electronic Systems Test Laboratory (ESTL) is a unique National Aeronautics and Space Administration (NASA) facility where multi-element crewed spacecraft communications systems are interfaced with relay satellites and ground elements for end-to-end testing in a controlled Radio Frequency (RF) environment. This facility is used for design evaluation, RF interface compatibility, and system performance verification testing of spacecraft RF communications systems and their interfaces with external (e.g., ground stations, relay satellites, detached payloads) elements. Space vehicle communications equipment is unlike other spacecraft systems since it interfaces not only with other equipment on the space vehicle but also with external equipment that is remotely located. The interface with the external equipment (e.g., relay satellites, ground terminals) serves as the lone link between the Earth-based elements and the space vehicles. Thus, communications verification testing between the external elements and the equipment on a crewed or unmanned space vehicle or high-valued payload is mandatory for successful flights.

    Tests are performed by operating the space, ground, and relay satellite communication systems simultaneously in a manner that accurately reflects actual space-to-space and space-to-ground mission configurations.
