SB SPACE @ ARL $ARLS004 ARLS004 SaudiSat 1-A (SO-41) now available for amateur use ZCZC AS04 QST de W1AW Space Bulletin 004 ARLS004 From ARRL Headquarters Newington, CT April 9, 2002 To all radio amateurs SB SPACE ARL ARLS004 ARLS004 SaudiSat 1-A (SO-41) now available for amateur use SaudiSat 1-A (SO-41) now is reported open for Amateur Radio communication. According to information received by AMSAT-NA President Robin Haighton, VE3FRH, SO-41 has been configured for FM voice repeater operation. Turki Al Saud, director of the Space Research Institute in Riyadh, Saudi Arabia--the satellite's sponsoring agency--told AMSAT-NA that SO-41 will automatically enable its UHF transmitter over Saudi Arabia and the US for approximately 20 minutes each pass. The spacecraft reportedly is configured for Mode J, with a VHF uplink of 145.850 MHz and a UHF downlink of 436.775 MHz. The spacecraft will operate in this mode intermittently, as power and spacecraft experiments permit, the announcement said. SO-41's downlink RF power is 1 W with left-hand circular polarization. The uplink antenna--located atop the spacecraft--is linear in polarization. Experiments and software development continue with SaudiSat 1-B (SO-42), and that satellite is not yet available to amateurs. SaudiSat 1A and 1B were launched along with TIUNGSAT-1 on September 26, 2000, from the Baikonur Cosmodrome, aboard a converted Soviet ballistic missile. Both satellites have been in various stages of commissioning since then. NNNN /EX
