2000 May 16 - 08:27 GMT - Launch Vehicle: UR-100N. Simsat-1 Mass: 657 kg (1,448 lb). Agency: Eurockot. Perigee: 543 km (337 mi). Apogee: 562 km (350 mi). Inclination: 86.37 deg. Period: 95.62 min. First Rokot flight from Plesetsk, using a launch pad originally used for Kosmos rockets. The two-stage modified UR-100NUTTKh ICBM, delivered a Briz-KM upper stage to a suborbital trajectory. The first Briz burn was to an approximately 200 x 550 km transfer orbit; the second burn circularized at apogee. It placed two 660 kg dummy satellites in orbits similar to the parking orbit was used for the defunct Iridium program. The Briz-KM stage then made a third burn to lower its perigee to a 178 x 556 km x 86.4 deg disposal orbit.
