1991-037A
The GE Satcom C-5 satellite was renamed Aurora 2 on reaching orbit; it is owned by GE Alascom and used for Alaskan domestic communications. The Series 3000 satellite had 24 C-band transponders.
1338 kg launch (Jane's); 644 kg BOL (Martin). About 180 kg hydrazine.
The transfer orbit perigee was 1440 km, occuring 30 minutes after launch. To reach such an altitude requires a steep climb; from the normal 185 km insertion orbit a 185 x 6700 km orbit is required to achieve the altitude in the required time and this seems unlikely. Alternatively a direct ascent orbit of -80 x 2625 km does the trick.
