GA-EMS Completes Initial Design Review of U.S.S.F.’s EO/IR Weather System Prototype Satellite Program Our Bureau 423 General Atomics Electromagnetic Systems (GA-EMS) completed the Initial Design Review (IDR) of the space vehicle and ground segment for the United States Space Force (U.S.S.F.) Space and Missile Systems Center (SMC) Electro-Optical Infrared (EO/IR) Weather System (EWS) satellite program.
