SRI International program partners
LeoLabs— acquired capability · strategic partner2 connectionsTell me more
SRI International developed radar and space domain awareness technology over 30+ years and spun it out in 2016 to create the independent company LeoLabs, which provides commercial satellite tracking and SSA services for LEO.
Relationship research record
SRI International partners with LeoLabs to provide access and time on the Poker Flat Incoherent Scatter Radar (PFISR) in Alaska for orbital tracking.
SRI International is listed as a collaboration partner on Genesis Engineering Solutions projects, including support for spacecraft systems development and testing.
SRI International received the David Sarnoff Research Center (Sarnoff) by donation from General Electric in 1986 and operated/maintained the laboratory as an independent non‑profit research organization, providing the operating and organizational capability that continued Sarnoff's activities.
