The third Advanced Extremely High Frequency (AEHF) satellite – a hybrid spacecraft that uses chemical and Hall Current Thruster electric propulsion for getting to its geostationary position - has begun transmitting. It joins two other satellites undergoing system test in orbit with a suite of user terminals. AEHF satellites are produced by Lockheed Martin for the U.S. Air Force. Launched on Sept. 18, 2013, AEHF-3 arrived in its final orbit position and began transmissions in January. Source: SpaceWar.com, 03/31/14) Previous.
