1974-033A
Synchronous Meteorological Satellite 1 was launched at 0931 on 1974 May 17 by Delta 2914 from Cape Canaveral. The Thor first stage shut down prematurely at 0935 after a LOX tank pressure loss; the Delta burned from 0935 to 0940 and reached a 155 x 213 km x 28 deg parking orbit with insufficent propellant to make its second 8s burn. After a 14 minute coast, the Star 37E third stage ignited at 0954. After it separated at 0956, SMS 1 was in a 182 x 33250 km x 24 deg transfer orbit, significantly lower in apogee than planned. The solid SVM-5 apogee motor fired at 0700 on May 19, and was followed by 9 daily thruster burns to raise the altitude. Finally on Jun 4 SMS 1 was near geostationary at 86 deg W. After a brief checkout it was stationed at 45W for GATE (the GARP Atlantic Tropical Experiment). SMS 1 was turned over to NOAA for operational use on 1974 Dec 10 despite problems with the S-band transmitter. By 1975 Oct it had been moved back to 75 W, which was to become the operational GOES East position. In early 1976 it was moved to 105W as a standby satellite, after being replaced by GOES 1. On 1979 Jan 26 it arrived at the GOES E position to replace GOES 2 in the First GARP Global Experiment (FGGE), but after SMS 1 had S-band transmitter problems in April GOES 2 took over again and SMS 1 moved to the side. SMS 1 spent 1980 at 131W backing up the GOES W position. On 1981 Jan 29 the orbit was raised by 500 km and SMS 1 was decommissioned a few days later.
