The US Air Force (USAF) and Lockheed Martin-led space-based infrared system (SBIRS) team has completed a major space to ground interface and functional system test for the first geosynchronous (GEO-1) satellite.

The first SBIRS geosynchronous spacecraft is equipped with highly sophisticated scanning and staring sensors.

The spacecraft will provide improved missile warning capabilities and support other critical missions simultaneously including missile defence, technical intelligence and battlespace awareness.

The test, known as 5001.4, verifies the spacecraft’s performance and interface with the ground segment.

The test demonstrated the capability to transmit data between the spacecraft and flight control facilities, and the ability of the SBIRS GEO-1 integrated ground and space system to perform critical operations.
