DSP-2, Polar. Satellite is 2.1m high 1.4m dia with mass 343 kg. DSP-P will have an orbit of 700 x 39000 x 90.0.
Launch southbound from Taiyuan; equator crossing at 0726 UTC. At 0735, the claimed insertion time, the satellite was over 110E 33S at 1200 km altitude.
If the burn was at the perigee of the final orbit, the Stage 2 orbit must have had a slightly negative perigee; the ground track is consistent with no inclination change. The delta-V required is lower than expected for the PKM.
Alternatively, the burn may have happened on the descending leg of the SM trajectory. At 0735 a preburn orbit of -4350 x 1500 km or -3643 x 1292 km would be consistent with the delta-V but not with a TYSC launch.
