SB SAT @ AMSAT $ANS-167.S1 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 167.S1 FROM AMSAT HQ SILVER SPRING, MD, JUNE 15, 2002 TO ALL RADIO AMATEURS BID: $ANS-167.S1 Phase 3D / AMSAT OSCAR 40 / AO-40 Launched: November 16, 2000 aboard an Ariane 5 launcher from Kourou, French Guiana. Status: Currently, the U/V/L-1/L-2 to S-2/K passband is active (various times) Uplink U-band 435.550 - 435.800 MHz CW/SSB L1-band 1269.250 - 1269.500 MHz CW/SSB L2-band 1268.325 - 1268.575 MHz CW/SSB Downlink: S-band 2401.225 - 2401.475 MHz CW/SSB K-band 24,048.010 - 24.048.060 MHz CW/SSB AO-40 experimental transponder operation started on May 05, 2001 at approximately 08:00 UTC when the U-band and L1-band uplinks were connected to the S-2 transmitter passband downlink via the Matrix switch. 7X0DX (9V1XE) has been active on AO-40, as has VU2MKP. AO-40 control stations (recognizing that a large number of stations would like to use AO-40 for as long as possible on Field Day) will omit the RUDAK session on Orbit 756, allowing another 2.4 hours of U/L->S2 operating time on Field Day Sunday. There have been multiple requests to try the V uplink and the operations team would also like to determine what the V-Rx hears in the way of hemispheric "interference" on 145 MHz. Therefore, as an initial test, from MA = 120 to 128 on Wednesdays only, the V-Rx will be connected to the S2 Tx, along with both L-band receivers. Operators with ~145 MHz IF's from their downconverters will experience extreme desense when trying to uplink on 145 MHz, but those with 435 MHz or other IF's should be able to hear themselves on the downlink. The uplink passband should be approximately 145.840 - 145.990. Please post observations to the amsat-bb. The K-Tx segment has been temporarily discontinued. We were experiencing some fluctuations in power output believed related to the very cold temperatures. Temperatures will begin to warm as the solar angle move to the Z+ end of the satellite, and the K-Tx sessions will resume in a few weeks. Upcoming DX: T88ZF from June 29-July 6, 2002 HB0 from July 13-14, 2002 TY, Benin from July 15-August 14, 2002 HK0ZZ from July 16-29, 2002 V63ZF from July 17-28, 2002.

Status: Non-operational The SunSat team released the following statement, dated February 1, 2001: We regret to announce that the last communication with SunSat from our ground station at the Electronic Systems Laboratory at Stellenbosch University took place recently. We are certain, after having performed several tests since the last contact, that an irreversible, physical failure has occurred on the satellite. It is therefore unlikely that we will have any further contact with SunSat, apart from the occasional visual sighting by telescope! When it was operational the SunSat package included 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system in addition to Mode B/J operation with two VHF and two UHF transmit-receive systems.

Status: Non-operational. WO-18 was last reported to be in MBL mode after a software crash. [ANS has no further information] ===== SEDSAT-1 SO-33 Downlink: 437.910 MHz FM (9600-baud FSK) Launched: October 24, 1998 by a Delta 2 rocket from Cape Canaveral, Florida. Status: Semi-operational. The satellite is not currently available for uplink transmissions and the image and transponder recovery efforts have been unsuccessful. SedSat-1 signifies Students for the Exploration and Development of Space (satellite number one). SedSat-1 has downlinked months worth of telemetry data on the performance of its electrical power system parameters. The Nickel Metal Hydride batteries on the spacecraft were experimental and experienced some abuse due to a power negative situation. This information has provided NASA with useful information. With the exception of the imaging system and the use of the transponders, SedSat-1 has been judged a success.
