U.S. Naval Research Laboratory - Artist's conception of the TIMATION satellite in orbit. TIMATION is an experimental navigation satellite launched on May 31, 1967 by NRL under a program sponsored by the Naval Air Systems Command. It weighs 85 pounds and has a 6-watt solar cell power source. The standby power required by the oscillator telemetry and other circuits is 3 watts. The satellite is gravity-gradient stabilized. A passive ranging technique is used both for the navigation of fixed and moving vehicles and for the accurate transfer of time between separated points. The gravity-gradient stabilizer, tethered at bottom, ensures the satellite will always be facing Earth. (U.S. Naval Research Laboratory)
