1997-048A
Two Iridium Mass and Frequency Simulators were launched on a CZ-2C from Taiyuan to demonstrate the capability of the CZ-2C launch vehicle and its new Smart Dispenser upper stage. The MFS were probably built by Motorola/Chandler, but are owned by China. The inert satellites, with a mass of around 650 kg, were designed to reproduce the mass distribution and oscillation frequency response of a real Iridium payload.
The apogee burn is about 125 m/s, while the reported capability of the SD is around 200 m/s with 125 kg propellant.
