JAWSAT Data - Part 3

As reported earlier in ANS, the JAWSAT launch (with amateur radio's newest satellites) has been postponed until early 2000. This delayed launch timeframe allows ANS to take a detailed look at each of the new birds. Last week ANS looked at OPAL, the Orbiting Picosat Automatic Launcher. OPAL will be part of the JAWSAT multi-payload adapter space-frame during launch. Following deployment, OPAL will in turn eject three small satellites, one of which will be STENSAT.

STENSAT is a small (12 cubic inch, 8.2 ounce) satellite, which is intended for use by amateur radio operators worldwide and will operate as a single channel, Mode-J, FM voice transponder (much like AO-27).

STENSAT will use an VHF uplink frequency of 145.840 MHz and a UHF downlink on 436.625 MHz. The satellite will periodically use 1200 baud packet for sending telemetry. Additionally, ham operators will be able to 'ping' the satellite by transmitting a six digit DTMF command string to the receiver uplink.

For more information on STENSAT, visit http://users.erols.com/hheidt/

A web cast of the launch of JAWSAT (and STENSAT) is available. To register for the web cast, visit http://www.webcastingtv.com/jawsat/

Straight Key Night on OSCAR

As ANS previously reported, if you are wondering how to welcome the new millennium -- Ray, W2RS, has the answer, straight key night on the active OSCAR satellites!

Ray invites satellite operators to participate in the 28th annual Y2K edition of Straight Key Night on OSCAR, sponsored by AMSAT-NA. The event is open to all radio amateurs worldwide.

As always, there are no rules, no scoring and no need to send in a log at the end of the event. W2RS tells ANS that SKN is simple - all operators need to do is operate using the continuous wave (CW) mode of transmission (with a hand key!) on any OSCAR satellite, or the moon (OSCAR-Zero), between 00:00 and 23:59 UTC on 1-January-2000.

All participants are encouraged to nominate the operator with the best fist among those they heard or worked.

Please send your nomination to W2RS:

via e-mail: w2rs@amsat.org

via packet radio: W2RS @ WA2SNA.NJ.USA.NA (or) W2RS @ GB7HSN.#32.GBR.EU

Ray also tells ANS that his listed callbook address is correct.

Best Fist nominees will be featured in an AMSAT News Service bulletin in early February and in the next available issue of the AMSAT-NA Journal following the contest end.

STS-103 Update

The Hubble repair mission, STS-103, is well underway as this edition of ANS is being prepared. After a flawless launch, Discovery and its seven astronauts successfully completed a two-day chase to catch up to and retrieve Hubble, closing on the telescope at a rate of about 340 nautical miles with each orbit of Earth.

As ground controllers at Goddard Space Flight Center placed the space telescope in an attitude with its closed aperture pointed toward Earth, Commander Curt Brown guided Discovery through an approach from below Hubble. Mission Specialist Jean-Francois Clervoy followed this maneuver by reaching out with the shuttle's robotic arm to grip Hubble itself. The successful 'grapple' was made about 24 hours after Discovery's launch from the Kennedy Space Center in Florida.

The first of three planned space walks to repair and upgrade Hubble equipment took place on Wednesday. Mission Specialist and Payload Commander Steve Smith and Mission Specialist John Grunsfeld first replaced the telescope's three Rate Sensor Units. Each contains two gyroscopes. The second major task completed was the installation of six Voltage/Temperature improvement kits between Hubble's solar panels and its six 10-year-old batteries. As Discovery astronauts completed these high priority tasks, they also completed the second longest spacewalk in history at 8 hours, 15 minutes.

Major tasks on Thursday's space walk by Michael Foale and Claude Nicollier included replacement of Hubble's outmoded DF-224 computer with a more modern unit 20 times faster and with six times the memory. They also replaced one of Hubble's three fine guidance sensors, used to precisely point the telescope and gather scientific data.

Discovery remains in excellent condition, in an orbit with a high point of 380 statute miles and a low point of 369 miles. The mission is on target for a December 27th return landing.

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.

S-band high speed downlink commissioning continues at rates between 128kb/s and 1Mb/s. The S-band downlink frequency has not been announced.

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 (at times) testing on 437.025 MHz at a baud rate of 38,400 (38k4). Currently, this downlink is switched on over Europe. Due to the limited power on UO-36, it is not possible to have this downlink on permanently over all areas.

Presently the BBS is still closed.

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