Sirio 2

Wiki

The cylindrically shaped spacecraft measured 144 cm in diameter and 240 cm in length including the apogee boost motor. The primary structural members are equipment platforms and a central thrust cone carrying conventional housekeeping electronics in addition to payloads. Attitude, orbit, and spin rate control were performed using a hydrazine propulsion system including four thrusters. The spin rate would have been maintained at 90 rpm throughout the two-year nominal lifetime. A mechanically despun antenna relayed S-band telemetry (meteorological and housekeeping), while a traditional omnidirectional turnstile system supported VHF ranging and telecommands, as well as housekeeping telemetry in transfer orbit and as backup geostationary orbit.
