Sicral, (Sistema Italiana de Communicazione Riservente Allarmi) was a communications satellite for the Italian defense ministry's procurement division, the Segretariato Generale della Difesa's Direzione Nazionale degli Armamenti. Sicral was built by Alenia Aerospazio and derived from the Italsat series. Its mass was 2596 kg full, 1253 kg dry and it carried a liquid apogee engine. The 3.3 kW, 3.4 m x 4.9 m, triaxially-stabilized spacecraft carried a total of nine transponders in the SHF-, UHF-, and EHF-bands to enable secure communications after parking over 16.2 deg-E longitude. Positioned in geosynchronous orbit at 16 deg E in 2001 As of 26 August 2001 located at 16.27 deg E drifting at 0.004 deg W per day. As of 2007 Mar 9 located at 16.34E drifting at 0.018E degrees per day.
- 2002 August 28 - Atlantic Bird 1 - Program: Eutelsat. Launch Site: Kourou. Launch Complex: ELA3. Launch Vehicle: Ariane 5. Mass: 2,700 kg (5,900 lb). Perigee: 35,786 km (22,236 mi). Apogee: 35,787 km (22,236 mi). Inclination: 0.10 deg. Period: 1,436.10 min.
Launch delayed from August 27. Atlantic Bird was a European (EUTELSAT) geostationary communications spacecraft. The 2.7-ton (1550 kg dry with 1150 propellant), 5 kW satellite was to provide voice, video, and Internet services to Europe and the eastern part of America through its 24 transponders after being parked over 12.5° W. As of 2007 Mar 10 located at 12.49W drifting at 0.006W degrees per day.
