Gurwin, also known as Techsat, were satellites built by the Technion Institute of Technology, Israel, and named for the philanthropist Joseph Gurwin (1920–2009).
Onboard instruments include CCD (charge-coupled device) cameras, radiation detectors, ozone monitors, and amateur radio transmitters. Gurwin 1B replaced an earlier satellite that failed to reach orbit.
