Anna 1A, 1B
Anna 1B [NASA]
Anna (Army, Navy , NASA, Air Force) was the first dedicated satellite for geodesy. It featured Xenon flashing lights and radio transponders (SECOR) for tracking the satellite. By pinpointing the satellites position, precise geodetic calculations could be made. Later the SECOR transponders were flown on dedicated SECOR satellites.
