1970-106A
The satellites following Tiros M were given ITOS designations, the first being ITOS A. By the time ITOS A was launched, by Delta from Vandenberg at 1130 on 1970 Dec 11, ESSA had become NOAA and so instead of being ESSA 10 the satellite was renamed NOAA 1 on reaching orbit. NOAA 1 operated in a 114.9 min, 1429 x 1479 km x 101.9 deg orbit until 1971 Aug 19 when its attitude control failed.
