The 13 CubeSats include nine NRO-sponsored nanosatellites and four NASA-sponsored nanosatellites.
“The GRACE CubeSats will perform missions demonstrating tracking technologies [and] software-defined radio communications and will also conduct other measurements and experiments,”Â Sponnick said.
According to ULA, NASA’s Jet Propulsion Laboratory, theÂ U.S. Army‘s Space and Missile Defense Center, SRI International, Aerospace Corp., AMSAT,Â Tyvak, University of Alaska – Fairbanks and Salish Kootenai College developed the CubeSats.
