Relationship research record
Government awards & missions SporeSat — ground-station-and-mission-data-relay-provider Tell me more SRI International operated SporeSat's primary ground station in Menlo Park, transmitting mission data to spacecraft operators at NASA Ames Research Center. · SporeSat biological-science CubeSat mission operations and data relay.
NASA's Open Science Data Repository identifies the primary ground station at SRI and its data-relay role to the NASA Ames mission-control operators.
mission context TechEdSat-6 and TechEdSat-7 — flight-demonstration-payload-provider Tell me more SRI International supplied its CUBIT identification-tag technology for on-orbit demonstrations aboard the TechEdSat-6 and TechEdSat-7 CubeSat missions. · On-orbit demonstration of low-power RF identification technology intended to distinguish small satellites shortly after deployment.
NASA records two successful CUBIT flight demonstrations on these host missions and identifies SRI as the technology builder.
mission context University of Michigan — spacecraft-development-and-science-partner Tell me more SRI International and the University of Michigan jointly conducted the RAX CubeSat mission, combining an orbiting receiver with ground-based bistatic-radar measurements. · Radio Aurora Explorer RAX-1 and RAX-2 CubeSat missions for ionospheric plasma-turbulence and auroral-scatter research.
The NSF–NASA annual report explicitly says the RAX mission was jointly conducted by SRI International and the University of Michigan. SRI's published RAX work describes its orbiting receiver and ground-transmitter measurement architecture.
customer organization National Science Foundation — research-program-funder-and-mission-sponsor Tell me more The National Science Foundation supported SRI International's participation in the Radio Aurora Explorer (RAX) CubeSat research effort. · Radio Aurora Explorer (RAX) space-weather and ionospheric bistatic-radar mission.
SRI states that it worked with NSF in 2010 to develop RAX; the joint NSF–NASA CubeSat report identifies RAX as a jointly conducted SRI–University of Michigan mission with two launched satellites.
government agency California Polytechnic State University — program-development-partner Tell me more SRI International and California Polytechnic State University partnered to develop the CubeSat Program; SRI developed portions of the CubeSat communications system. · CubeSat Program and subsequent PolySat-associated CubeSat development, including the ISX mission.
SRI identifies Cal Poly as its partner in developing the CubeSat Program in 2000 and states that it contributed CubeSat communications-system elements. NASA separately identifies SRI and Cal Poly PolySat as collaborators on ISX.
