ISS Update

NASA tells ANS that flight control teams in Houston and Moscow continue to monitor the health of the International Space Station systems, reporting no significant problems on board other than a balky battery that currently is not being used for electrical power.

Plans continue to be finalized for the tests later this month to rehearse the docking of the Zvezda service module with ISS, currently planned for November. The test will have the station maneuver to the desired docking orientation followed by activation of the Kurs automatic docking system. Zvezda will serve as the early living quarters for the crew as well as providing life support and command and control capability.

Routine activities this week included completing battery capacity restoration in Zarya. This procedure fully drains and then recharges batteries to maintain as long a life as possible on the units. Capacity restoration of the batteries is performed about every six months to minimize charge memory, similar to the maintenance of rechargeable batteries used in many ham radio communication items.

The possible degradation seen in battery number one continues to be monitored and the battery currently has been removed from the electrical bus. A replacement battery and associated electronics may be carried to the station on the next Shuttle assembly mission, STS-101, now targeted for launch in December. The crew of STS-101 is also scheduled to install four ham radio antenna packages (HF, VHF, UHF, and L/S band) on the outside of the ISS modules during a mission spacewalk. STS-101 will also carry the initial VHF and UHF ham station which will employ both FM voice and packet. This initial station will be left on the space station for use by future crews.

On the ground, a command server problem has been solved that briefly prevented command transfer from Moscow to Houston. Though the Russian Mission Control and ground stations remain the prime means for commanding to the ISS, the Unity node's early communications system can be used through NASA's tracking network as a backup. An inadvertent file prevented the two servers from 'talking' to one another, but the problem was corrected within a day.

The International Space Station is oriented with Unity pointed toward Earth and Zarya pointed toward space in a slow spin to conserve fuel and maintain an even temperature for both modules. ISS is flying in a slightly elliptical orbit with a high point of 249 statute miles and a low point of 236 statute miles, circling the Earth every 92 minutes. The complex has completed 4,132 orbits since the launch of Zarya last November.

LU1AHC Silent Key

ANS is saddened to report the death of Arturo Carou, LU1AHC, who recently passed away in Houston, Texas after a short illness. A memorial ceremony was held August 11th.

Arturo devoted much of his life to satellite operation and was very instrumental in helping place AMSAT-Argentina's first satellite -- LuSat -- into orbit. He was a founder and permanent member of AMSAT-Argentina. A long-time promoter of satellite activity, LU1AHC published satellite timetables long before the advent of the personal computer or software tracking programs.

AMSAT-NA President Keith Baker, KB1SF, told ANS "this is very sad information. Arturo was a key part of the LuSat project. His presence among us will be sorely missed." Pedro Converso, LU7ABF, AMSAT-Argentina Vice President, reported Arturo was "always a gentleman despite his multiple activities that included management in several civil organizations. He represents the impulse that brought Argentina into Amateur Radio satellite activity. We miss you Arturo, but will never forget."

[ANS sends the condolences of the entire satellite community to the family of Arturo Carou and thanks AMSAT-NA President Keith Baker, KB1SF, for this information]

The PBBS is running a Kantronics KPC-9612 + V.8.1 TNC. The commands are similar to most PBBS and BBS systems.

Ham radio activity aboard Mir has greatly increased in the last several weeks as the three person crew prepares to return to Earth. Mir is soon to be left in a stable orbit with only essential systems running. All amateur radio activities will cease and the equipment will be turned off before the crew leaves. The final fate of the space station has not been formally announced.

Stay tuned to ANS for further developments.

French astronaut Jean-Pierre Haignere, FX0STB, has used almost every moment of his free time recently in an effort to contact as many Earth bound ham operators as possible in the short time remaining before the crew returns home. Reports of successful QSO's or packet/SSTV activity have been reported by many stations on AMSAT BB.

The QSL manager for FX0STB is:

PANSAT PO-34

Downlink frequency not established.
The satellite is not currently available for uplink transmissions.

PANSAT, developed by the Naval Postgraduate School, was launched from the shuttle Discovery. PANSAT spread-spectrum digital transponders will be available to amateur radio operators in the near future along with software to utilize this technology. The PO-34 command station is located in Monterey, California.

Dan Sakoda, KD6DRA, PANSAT Project Manager recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme.

SunSat SO-35

SunSat was launched February 23, 1999 aboard a Delta II rocket from Vandenberg Air Force Base in California. SunSat stands for Stellenbosch University Satellite and takes it name from the South African university whose students constructed the payload.

The second 'test' of SunSat in FM repeater mode took place on 11-July-99 and was quite successful with many stations active and a large number of contacts made through the bird.

The SunSat package includes 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system that will be used primarily for educational demonstrations. The satellite has two VHF and two UHF transmit-receive systems.

UoSAT-12 UO-36

Downlink 437.025, 437.400 MHz

UoSAT-12 was successfully launched on April 21, 1999 from the Russian Baikonur Cosmodrome. UO-36 carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.

The satellite is not currently available for general uplink transmissions.

UO-36 has been transmitting 9600-baud FSK telemetry framed in a VLSI format using a downlink frequency of 437.400 MHz. Chris, G7UPN, reports UO-36 is also transmitting on 437.025 MHz at 38,400 (38k4) baud. Presently the BBS is still closed.

S-band high speed downlink commissioning continues at rates between 128kb/s and 1Mb/s.

VK5HI TMSAT viewer software is available on the AMSAT web/ftp site at ftp://ftp.amsat.org/amsat/software/win32/display/ccddsp97-119.zip
