About this launch
With the launch of Nilesat 101 on 28 April 1998, delivering more than 100 digital TV channels as well as radio and multimedia services to more than five million homes over the whole of North Africa from Morocco to the Persian Gulf, Egypt became the first African country to have its own direct TV broadcast satellite. A second satellite, Nilesat 102, was launched in 2000, and the Nilesat system now broadcasts more than 150 digital TV channels and provides additional services such as data transmission, turbo internet and multicasting applications. BSAT-1a and -1b replaced the two BS-3 spacecraft used for DBS services, including Hi-Vision test broadcasts, by NHK, WOWOW, and others. Hughes selected the Ariane rocket as the launch vehicle for the BSAT-1 spacecraft. BSAT-1a was launched 16 April 1997 from the Guiana Space Center in Kourou, French Guiana. BSAT-1b was also launched from Kourou on 28 April 1998. The two satellites are located at 110 degrees East longitude.
