SB SAT @ AMSAT $ANS-077.01 PHASE 3D / AMSAT OSCAR 40 UPDATE AMSAT NEWS SERVICE BULLETIN 070.01 FROM AMSAT HQ SILVER SPRING, MD, MARCH 18, 2001 TO ALL RADIO AMATEURS BID: $ANS-077.01 To All Members of AMSAT-NA, The following statement is addressed to those members of AMSAT-NA who have requested an explanation of the December 2000 incident that took place on P3D. This statement has been prepared and developed by Robin Haighton, VE3FRH, President of AMSAT-NA, with input and review from other AMSAT-NA members. As you are aware, Phase 3D was launched on November 16, 2000 into an almost perfect geosynchronous transfer orbit (GTO) by an Arianespace launch vehicle (AR-507) from Kourou, French Guiana. Within a few hours of launch excellent telemetry was being received from the 2-meter beacon, and Amateur Radio stations worldwide started downloading data with great accuracy, due in-part to the strong signal strength. The original plan was to use the 70-cm beacon, however, for reasons not yet known, the 70-cm transmitter signal was not heard. Before the satellite could be regularly used for general Amateur Radio communications, it was necessary to carry out orbital changes, stabilize the satellite, open the solar panels, etc. The first changes to the orientation of the satellite were carried out using the onboard magnetorquing system - this worked well and after relatively few orbits the attitude of (now) AO-40 was 270/0, and ready for operation of the 400 Newton motor. Among the many components which comprise this motor system, there are several valves which control pressurizing helium and fuel. During construction of the satellite it was noted that one of the helium valves had a tendency to "stick" when operated. Both of these valves were sent back to the manufacturer for inspection and repair. Both valves were inspected and one valve was repaired, followed by return and re-installation into the system. On the first attempt to fire the 400-N propulsion system, it failed to operate, possibly due to a sticking helium valve. Before the second attempt, it was determined that the fuel tanks could be pressurized (by helium) to their correct pressure over a five minute period, and although this was about one-tenth of the normal helium flow rate, it was still adequate for the planned three minute motor burn. On the second attempt to fire the 400-N motor, all systems appeared to respond correctly at first. At the three minute mark the internal timer transmitted a signal for the main solenoid valve to close, which should have shut off the fuel to the motor. Telemetry shows that the signal was sent and received, but the motor did not shut off for two or three more minutes, placing AO-40 into a higher apogee orbit than was planned at that time. To understand how this may have happened, it is necessary to be aware that the fuel for the 400-N motor is made up of two components, hydrazine (MMH) and nitrogen tetraoxide (N2O4), with each component contained in two separate tanks, both of which could be pressurized by helium. Helium could also be applied to the solenoid motor valve, the output of which operates the two fuel valves which start (and stop) the fuel flow. These valves are actually part of the 400-N motor and are located inside the motor itself. On the solenoid motor valve there is an evacuation port that allows excess helium at the output port of the valve to escape when closing the valve. It is believed that this evacuation port was blocked and that the output port remained pressurized beyond the three minute mark of the motor operation - thus the motor continued to burn for an extended period of time. Between the fuel tanks and the 400 Newton motor there are fuel isolation valves which are pressure operated by the helium system. When the pressure in the helium manifold had been reduced to approximately 6-Bar (100 PSI) the fuel isolation valves closed and prevented any additional fuel from entering the motor, stopping the burn. At this time it is possible that the main motor valves were still open, due to the trapped pressurized helium that had not vented at the solenoid motor valve. Approximately twelve minutes after the motor shut down, a second anomaly occurred. This was detected when the motor solenoid valve changed from closed to open, possibly caused by fuel migrating in the lines between the isolation valve and the 400-N motor. The motor could have also "burped" or "popped" as the fuel mixed and then ignited. High pressure helium (180 Bar) is fed to the motor system via a high pressure on/off valve and a regulator valve - reducing the pressure to a nominal 15 Bar level. It is then fed to the low pressure helium manifold. Because of the longer 400-N burn, a program for testing the high pressure helium valve was written to "cycle" the valve (to insure proper functioning) and uploaded to AO-40. On December 11, 2000, while cycling the helium valve, a sudden loss of signal from AO-40 occurred. It is believed that during this exercise the system became pressurized and that a leakage of fuel was the end result. Initial thoughts were that the spacecraft was completely dead and that chances of recovery were remote, with the possibility that AO-40 was in multiple pieces. However, with help from NORAD, it was determined that the satellite was in one piece, with a possibility of some recovery. At least two automatic resets passed without hearing from the spacecraft. It was decided to try and hear the general beacon on the S-band (2.4 GHz) transmitter. On Christmas Day 2000 the second attempt to activate the S-band transmitter was successful, and since that day downlink telemetry has been recovered on a regular basis. The following items have been found to be working; the 2-meter, 70-cm and 1.2 GHz receivers, the S-2 (2.4 GHz) transmitter, the magnetorquing system, the YACE camera, IHU-2 and the high-gain antennas. The following items are believed not to be working; the 2-meter and 70-cm transmitters and the omni-directional antennas. At the time of this bulletin (March 16, 2001) we still do not know the status of the Arc-jet motor - which is an important item, needed to position the satellite for future use. We do know that the satellite has lost mass, and we attribute this to the loss of bi-propellant fuel from the 400-N motor. The satellite spin rate had increased as the overall weight decreased, but by using the magnetorquing system the spin rate is now nearly down to a usable 5 RPM. In addition, the heat pipe system (which became unusable at the higher spin rates) has now become effective again. Soon AO-40 will be able to be re-orientated so that the high-gain antennas will face the Earth, and the Arc-jet motor will be tested. Following the re-orientation it will be possible to test the remaining systems on board the spacecraft and to determine which systems and bands will be available for future operations and under what conditions. As we all learn more about the status of the satellite, additional bulletins will be posted on AMSAT-BB, and placed on the AMSAT-NA, AMSAT-DL and AMSAT-UK web sites. Meanwhile, all those involved in the recovery of AO-40 are to be congratulated for their skills and perseverance, and may their hard work continue to bring us an operational satellite. 73, Robin Haighton VE3FRH President AMSAT-NA AO-40 is currently transmitting the following message in the A-Block MOTD: Magnetorquing!!

Two more full days of joint work remain before Discovery is scheduled to undock from ISS. A third and final re-boost of ISS will also take place using the shuttle's small steering jets to raise Alpha by a little over two statute miles. Altogether, Discovery will leave Alpha a little more than seven miles higher than when it arrived. The ISS Expedition-2 crew is getting right to its school contacts! The John B. Reible School, in Santa Rosa, California is scheduled for the week of March 26th, with the Vicksburg, Mississippi High School group scheduled for early April. Late breaking news: Randy, KG3N, reported "this morning I heard astronaut Susan Helms calling CQ onboard the International Space Station. I gave here a call (and using the NA1SS callsign) she came back to me. I was able to talk to her for 45 seconds." It appears Susan will be very active (as promised).

Several organizations (such as CNN) are planning live coverage of the de-orbit as it happens. The Russian outpost is the heaviest thing orbiting our planet other than the Moon itself! During its 15-year stint in space, Mir has set endurance and space adventure records, along with providing hundreds of Amateur Radio contacts between ham radio satellite operators and onboard cosmonauts and astronauts. Scientists expect the space station to put on a good show when it returns. Mir is put together much like an erector set. It's an assortment of solar arrays, laboratories and living quarters that was not designed for aerodynamic flight through the atmosphere. Mir has a core module and five other components weighing about 143 tons in all. With a cargo ship and an escape capsule attached, it weighs up to 154 tons. The modules are arranged in a T-shaped structure, 86 by 96 by 99 feet. The station will quickly fall apart as it descends toward Earth. "We expect Mir to break into six or more main pieces when it hits the atmosphere," said Nicholas Johnson at NASA's Johnson Space Center. Each piece will resemble a blazing meteor that spits smaller fireballs as the pieces crumble and burn.

The FCC also canceled an experimental license grant to the City of Los Angeles to operate an identical TV downlink system in same band. Amateurs have a primary domestic allocation at 2402-2417 MHz and a secondary allocation in the rest of the affected band. -ARRL, AMSAT-NA ** The ARRL has suggested that the FCC expand the secondary amateur allocation at 219-220 MHz to provide access to the entire 216-220 MHz band. The League commented this month in response to a Notice of Proposed Rule Making, ET Docket 00-221, that proposes to reallocate 27 MHz of spectrum in various bands, including 216-220 MHz, from government to non-government use. In general, the FCC seeks to allocate the entire 216-220 MHz band to the Fixed and Mobile services on a primary basis. -ARRL ** The ARRL is urging the FCC to deny or dismiss a petition that seeks to boost the field strength and duty cycle of RF identification systems deployed as unlicensed Part 15 devices in the 420-450 MHz band. The League filed comments March 1 in a petition filed by SAVI Technology Inc. The petition, designated RM-10051, asks the FCC to change certain Part 15 rules affecting unlicensed, periodic, intentional radiators. SAVI, which markets radiolocation and wireless inventory control products, says it needs the rules changes to satisfy customer demand for increased RFID system capabilities. -ARRL ** A newly released pair of images taken by NASA's Galileo spacecraft has captured a dynamic eruption on Jupiter's moon Io. They images show a change in the location of hot lava over a period of a few months in 1999 and early 2000. -SpaceDaily ** The Administrative Council of the International Amateur Radio Union has selected the theme "Providing Disaster Communications: Amateur Radio in the 21st Century" for World Amateur Radio Day, April 18, 2001. IARU has been the watchdog and spokesman for the world Amateur Radio community since its founding in Paris, France, in 1925. Hiram Percy Maxim, 1AW, was its first president. -ARRL ** An international team of researchers has discovered compelling evidence that the magnetite crystals in the martian meteorite ALH84001 are of biological origin. The researchers found that the magnetite crystals embedded in the meteorite are arranged in long chains, which they say could have been formed only by once-living organisms. -SpaceDaily ** When last reported, Randy, N7SFI, was only one grid square away from completing his quest to work all the grid squares in the 48 contiguous states! Congratulations Randy! -AMSAT BB ** An Ariane 5 was launched recently from the Kourou spaceport in French Guiana. Flight 140 transported a dual satellite payload: the Eutelsat EUROBIRD satellite BSAT-2a from Orbital Sciences. -SpaceDaily ** The Amateur Radio Spectrum Protection Act of 2001 is now officially HR 817. Rep Michael Bilirakis of Florida introduced the bill on March 1st in the U.S. House of Representatives. ARRL President Jim Haynie, W5JBP, and ARRL First Vice President Joel Harrison, W5ZN, visited the Congressman's office to thank him personally for his continuing interest in protecting Amateur Radio frequency allocations. -ARRL ** Scientists from Bell Labs have created the world's first plastic material in which resistance to the flow of electricity vanishes below a certain temperature, making it a superconductor. The plastic, is an inexpensive material that could be widely used in the future for applications, such as quantum computing and superconducting electronics. -SpaceDaily --ANS BULLETIN END--- /EX SB SAT @ AMSAT $ANS-077.06 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 077.06 FROM AMSAT HQ SILVER SPRING, MD, MARCH 18, 2001 TO ALL RADIO AMATEURS BID: $ANS-077.06 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 recently 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.
