SB SAT @ AMSAT $ANS-217.01 AO-40 UPDATE AMSAT NEWS SERVICE BULLETIN 217.01 FROM AMSAT HQ SILVER SPRING, MD, AUGUST 05, 2001 TO ALL RADIO AMATEURS BID: $ANS-217.01 AO-40 status continues this week as before; currently the U/L-1 to S-2 passbands are active. The current ALON/ALAT is providing low squint angles (especially in the Northern Hemisphere), allowing excellent downlink signals. 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 for the first time - via the onboard Matrix switch. AO-40 command station Stacey Mills, W4SM, tells ANS that orbit 345 (which started at approximately 19:50 UTC on July 30th) was significant because it featured continued testing of the RUDAK system. During orbit 345, which was visible by South America, most of North America, Africa, and Europe; the transponder passbands and the middle beacon were on from MA-10 to MA-37. At approximately 22:35 UTC (MA-37), the transponder passband and middle beacon were turned off for RUDAK software loading. RUDAK testing continued on August 3rd, during orbit 349. W4SM also reports that for the immediate future, the passbands can be assumed to be on from MA-10 through 99. Stay tuned to ANS, the official source of AO-40 information.

With models for the catastrophic origin of the Moon by glancing collision, it becomes clear that our Moon is a rare celestial object and that few Earth-like planets could have produced such a chance outcome during their assembly. -SpaceDaily ** ESA is organizing Teach Space 2001, the first ISS education conference for teachers, this October in the Netherlands. ESA is inviting teachers to enter space-related projects for this event. The conference will enable teachers, companies and space enthusiasts to share ideas with colleagues from other European countries. Teachers will also have an opportunity to show their own space projects with the best space projects selected for presentation. -ESA ** Will, KC6ROL, and Charlie, AJ9N, report the Joan Martin School ham contact with Jim Voss aboard the International Space Station (using NA1SS)went very well. Mike, KF9WW, was the control operator for the contact and he and his crew did a great job. Contact was made with the space station within about 5-seconds of AOS! Seventeen students had their questions answered before loss-of-signal. There were two newspapers and a PBS TV station at the school to watch the contact. Congratulations to all! -ANS ** Boeing Satellite Systems and IBM recently announced they have created what they feel is the world's most powerful satellite-based digital signal processor, designed to make space-borne wireless communications available to a wide audience of users. -SpaceDaily ** Meeting recently in Connecticut, the ARRL Board of Directors adopted a goal of legislative action to provide amateurs the same protections from real estate covenants, conditions and restrictions now enjoyed under FCC rules by home satellite dish owners. BOD members felt that amateurs should be granted the right to install an antenna having a visual impact similar to that of a home television satellite dish or other antenna that falls under the FCC's Over the Air Reception Devices policy. -ARRL Letter ** The latest AMSAT-ZL Newsletter included an article on four of the more popular S-band downconverters. Following this, AMSAT-ZL members conducted additional bench tests and posted the results the AMSAT-ZL page at: http://www.nzart.org.nz/amsatzl/downcons.html -Terry ZL3QL. ** China is said to be ready to launch its third unmanned spaceship soon to pave the way for sending the first Chinese astronaut into space sometime next year. In addition, China is in final testing and preparation to launch a new satellite dedicated to study ocean colors and related phenomena. The launch may come as early as this month. -SpaceDaily --ANS BULLETIN END--- /EX SB SAT @ AMSAT $ANS-217.04 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 217.04 FROM AMSAT HQ SILVER SPRING, MD, AUGUST 05, 2001 TO ALL RADIO AMATEURS BID: $ANS-217.04 Phase 3D / AMSAT OSCAR 40 / AO-40 Launched: November 16, 2000 aboard an Ariane 5 launcher from Kourou, French Guiana.

Status: Operational at 38k4-baud FSK Chris, G7UPN, tells ANS that TiungSat-1 has been operating at a data rate of 38k4. Data recovery at 38k4 is reported to be extremely good with efficiencies near 100%. The output power is at 8-watts "which should provide a very good downlink," said Chris, adding "the downside is that with the high power transmitter operating, the power budget is negative so we can't support continuous operation." According to G7UPN, TiungSat-1 now requires the Amateur Radio station to switch the downlink 'on' when the satellite comes into range. The way this works is for the ground station software to send a request to the spacecraft to switch the downlink on. The spacecraft receives this request and checks the battery voltage to see if it can support the operation, and if it can it will activate the downlink. TiungSat-1 is Malaysia's first micro-satellite and in addition to commercial land and weather imaging payloads offers FM and FSK Amateur Radio communication. TiungSat-1, named after the mynah bird of Malaysia, was developed as a collaborative effort between the Malaysian government and Surrey Satellite Technology Ltd.

Status: Non-operational Chris, G7UPN, reported that UO-22 has been closed for amateur activity for a short duration while command stations assess the state of the RAM disk. Over the past few weeks there have been increasing difficulties downloading larger files from the spacecraft. The store and forward communications system was reloaded recently and it is hoped that that this will fix the problem. Once the problem has been assessed and resolved the BBS will be reopened. UO-22 has been operating at 100% since the last reload in November 1999.

Status: Operational Clive, G3CWV, reported to ANS that during the period 09-June to 14-July there have been three noteworthy events with OSCAR 11. First, reports of unusually strong mode-S beacon reception were received from VK5HI and G4SDG. A possible explanation for these strong signals might be that the fault which has caused low output power for many years, may be intermittent, perhaps triggered by the lower battery voltages which are currently occurring. Ground control have confirmed that the S-band beacon has the same modulation as the 145 MHz beacon, but the modulation level is very low. Secondly, the rate at which the SEU counter increments has approximately doubled, to about 390 counts per day. Decoding the SEU binary telemetry shows regular memory failure at locations 3EC0 and 37B1. Less frequent faults at locations 1873 and 18F3 have also been recorded. The failure of 3EC0 started around 12-May 2001. Location 37B1 failed in August 1994. Unfortunately the presence of permanent memory failures masks the occurrence of less frequent random memory failures, which could be observed before the 1994 failure. Finally, the Z-axis magnetorquer counter reached its limit of 1024 on 23-June. This has stopped further active attitude control. The satellite's attitude is now controlled solely by the passive gravity boom gradient. Prior to this the spin control had been working well, with periods in range from 338 to 343 seconds. Reliable signals have been received from the 145 MHz beacon. The battery voltage observed during daylight passes is unchanged with average value observed at 13.4 - with a range of 13.0 to 13.5 volts. The internal temperatures have continued to decrease by a further one degree C and are now at -1.2C and -2.6C for battery and telemetry electronics respectively. The WOD survey of channels 1, 2, 3, 61 (X, Z, Y magnetometers and status) dated 24-March, has been transmitted. OSCAR-11 hardware generated time in the ASCII telemetry is now 15.5 minutes ahead of UTC, and the date is three days advanced. Unfortunately these errors cannot be corrected.

Status: Semi-operational. Efforts were reported to be underway to bring GO-32 on line, however, no information has been received by ANS (the last report was dated November 1999). Last reported, the satellite does transmit a 9600-baud burst every 30 seconds (the GO-32 beacon sends one short telemetry status transmission of 44 bytes) and upon request the complete telemetry buffer. [ANS has no further information] PANSAT PO-34 Uplink/downlink frequency (listed on the PanSat web site) 436.500 MHz Launched: October 30, 1998 by the Shuttle Discovery. Status: Unknown The satellite is not available for general uplink transmissions. The Naval Postgraduate School developed PanSat. At the time of launch, PanSat spread-spectrum digital transponders were promised to be available to Amateur Radio operators along with software to utilize this technology. To date, this has not happened. For more information, visit the official PanSat web site at: http://www.sp.nps.navy.mil/pansat/ PanSat was the featured cover article on the July/August 1999 issue of the AMSAT-NA Journal (the story written by KD6DRA and N7HPR). [ANS has no further information] DOVE DO-17 Downlink 145.825 MHz FM (1200-baud AFSK) 2401.220 MHz Launched: January 22, 1990 by an Ariane launcher from Kourou, French Guiana. Status: Non-operational. DOVE stopped transmitting in March 1998. The 145.825 MHz and 2401.220 MHz downlinks are off the air and the satellite has not responded to ground station control. [ANS has no further information] WEBERSAT WO-18 Downlink 437.104 MHz SSB (1200 baud PSK AX.25) Launched: January 22, 1990 by an Ariane launcher from Kourou, French Guiana. 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.
