The TC-1 satellite
Tan Ce (Explorer) 1, or Double Star DSP-E, Chinese/ESA magnetospheric satellites, to supplement the Cluster system and using backup European Cluster instruments. Equatorial DSP-E 550 x 66970 x 28.5 planned orbit. Launch Dec 2003 and Apr 2004 by CZ-2C/SM (or CTS). CTS top stage derived from SD. Places 1400 kg in SSO. Has FG-47 solid motor.
Spin-stabilized satellites, 350 kg built by CATC's Space Tech Inst. Spacecraft is a 2.1m dia 1.4m high spin stabilized (15 rpm) cylinder, with overall size 4.0m high 8.3m span. Used a direct ascent orbit with all three stages burning without coast phase, giving perigee around 23 deg N.
The PKM was described in a paper at IAC 2004. It is 1.4m dia. Mass is 2929 kg full, 2620 kg prop, 309 kg dry. Total impulse is 7477 kNs and Isp is 291.0s (Ve=2.854 km/s). For a TC-1 mass of 350 kg, the rocket equation gives a dV of 2.854 ln ( 3279 / 659 ) = 4.579 km/s.
Another source gives SM? 2.7m dia 1.5m long, 125 + 50 kg prop, 10.7 kN, Ve 2804 SMA: 2.7m dia 0.9m long, 21.7 kg propellant, 10.4 kN, Ve 2804 SM: 1.4m dia 2.3m long 2620 kg prop, 101 kN Ve 2863
Apogee was higher than planned.
