TDF-2 was a French telecommunications satellite launched using the Ariane launch vehicle by the European Space Agency. It was the second 5-channel direct broadcast satellite built for Telediffusion de France by the European Eurosatellite consortium. It provided TV and radio programming to France, surrounding European countries, and a sliver of North Africa using the D2 MAC Packet standard. DTF-2 operated at 11/12 GHz, with a maximum EIRP of 64 dbW per channel. Box-shaped, the satellite measured 6.2 by 2.4 by 2.2 m, and spanned 19.3 m with solar arrays deployed. It joined TDF-1, Ariane-launched in 1988, at 19 deg. w long. The satellite had a 9-year life expectancy, but suffered two transponder failures two months after achieving operational status. The losses have not affected service, but do limit backup options. The French government announced in November, 1990 that the TDF program would be discontinued in favor of more current technology.
