1983-030A
The RCA F payload, an Advanced Satcom bus built by RCA Astro Electronics, was launched in 1983 to replace Satcom 1 and was named Satcom 1R on reaching orbit. In 1988 the satellite became the property of GE Americom.
The post launch MOR records the apogee burn time as Apr 14 1430 EST (well, it says EDT but that is an obvious error). The final transfer orbit TLE from Apr 13 puts the spacecraft at 140W at that time at 7th apogee, while the first post-burn TLEs from Apr 15 put it at 90W. Perhaps a further burn occurred prior to the Apr 15 data - those TLEs put the vehicle at 103-107W on Apr 15-16. More likely, however is that the MOR document, despite its almost contemporary nature (dated 1984 Jul 26) and official provenance, is in error and the burn was delayed to 9th apogee on Apr 15 at 1700 UTC.
