AfriSpace requested authority to modify its license for AfriStar-1 at 21 degrees east longitude (EL) to utilize an alternative downlink beam configuration and to transmit with carriers with 1.71 MHz bandwidth in addition to its recently authorized 2.6 MHz bandwidth. AfriSpace said the modifications were necessary to meet customer demand and to accommodate the satellite’s diminishing power. From FCC Report SAT-00510.
The FCC withdrew the special temporary authority (STA) authorized in file SAT-STA-20080306-00059. This STA allowed EchoStar to move EchoStar 3 from 61.5 degrees west longitude (WL) to 61.35 degrees WL while traffic was transitioned to AMC-14. As previously covered in RF Report, AMC-14 failed to achieve geostationary orbit after launch.
