2003-018A
GSAT-2 launch mass was 1823 kg, 840 kg dry. Prop was MMH/MON-3. Size 2.4 x 1.6 x 1.5m with 9.6m span. Launch 2003 May by GSLV-D2 into GTO; LAM to GEO at 48E.
D2 had 10t of extra prop in stage 1, and improved strapon and stage 2 engines. Mass 414t at launch. The S139 first stage has four L40H strapons. GS2 is 11.6l 2.8d with 39.3t prop of UH25/N2O4 and 804 kN thrust. GS3 is cryo, 8.7l 2.9dia. The payload adapter was also made lighter, for a total gain of 485 kg; the lower-than-design Isp of the 12KRB represented a loss of 200 kg.
Launch from SDSC-SHAR (Satish Dhawan Space Center). Azimuth 104 deg.
The satellite carried SOXS, a solar X-ray spectrometer.
