CAT 1, 2 (CATsat 1, 2)
CAT [JHU/APL]
CAT (CubeSat Assessment and Test) is low-cost CubeSat mission consisting of two 3U CubeSats led by the Johns Hopkins Applied Physics Laboratory in Laurel, Md., for the Department of Defense (DoD) to demonstrate communications technologie.
CAT uses two commercial off-the-shelf spacecraft to support a government furnished equipment communications experiment to be launched from the International Space Station.
CAT is built on Blue Canyon Technologies (BCT) provided XB1 triple (3U) CubeSat busses.
Both satellites were launched to the ISS in late 2018 and were deployed on 31 January 2019.
