Horizons 1



HORIZONS 1 (GALAXY 13) is a joint American-Japanese (i.e, PanAmSat- JSAT corporations) geostationary communications spacecraft that was launched by a Zenit 3 rocket from the floating platform Odessey in equatorial Pacific ocean on 1 October 2003. The 2.6 tonne (4.06, including the fuel), 9.9 kW satellite carries 24 transponders each in the C- and Ku-bands to provide digital video, internet, and data services to the countries on either side of the Pacific ocean after parking over 127 deg-W longitude. The alternative designation of GALAXY 13 is adopted from the fact that the C-band component is a legacy of the GALAXY series and its co-owner PanAmSat who will control it, not the JSAT.
