UoSAT-12 Healthy

UoSAT-12, amateur radio's newest satellite, has successfully completed almost two weeks in space. The satellite carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.

The operations team at the Surrey Space Mission Control Center report to ANS that on-board software has stopped the tumbling of the satellite after release from the launcher. The momentum wheel on the bird was also tested and confirmed as operational. UoSAT-12 is now in a 3-axis stabilized Earth pointing mode.

The first images of Earth from the four remote sensing CCD cameras on-board the mini-satellite have been successfully received. The first image from the 10-meter resolution panchromatic camera was taken over Texas and later downloaded for evaluation. The image showed good detail, confirming camera function and focus. After adjusting the camera, a second image over London was captured.

Recently a panchromatic image and a 32-meter single-band image from one of the two multi-spectral cameras were captured simultaneously over Los Angeles, clearly showing airport runways, housing, dockyards and freeways.

UoSAT-12 also carries a wide-angle color CCD imager for meteorological imaging and this has been used regularly during the past week for Earth cloud cover monitoring. The data from the imaging CCD cameras are compressed on-board the spacecraft prior to transmission to the ground. Very highly-compressed, quick-look 'thumbnail' images are also available and enable ground operators to assess the image quality and content prior to downloading the full image.

Spacecraft operators are now refining the camera settings through a series of continuing test images and the first images for release are expected soon. In addition, opening the transponders aboard the satellite for general amateur use is being planned, along with official OSCAR number designation.

Second Call for Papers

As announced previously by ANS, recent and future development in amateur radio satellites will be presented in San Diego, California, October 8-11, 1999, at the 17th Space Symposium and AMSAT-NA Annual Meeting.

This is the second call to authors who wish to present papers at the Symposium. Presentations will also be printed in the official Proceedings document. You do not need to be a member of AMSAT-NA to present a paper or attend the Symposium.

The subject matter should be topics of interest to the Amateur Radio satellite service. One page abstracts are due and should be submitted as soon as possible for consideration. Other key dates for submitting papers are as follows:

June 01, 1999 - authors will be advised if accepted
August 01, 1999 - camera ready copy of accepted papers due

Abstracts should be sent to Symposium chair Duane Naugle, KO6BT, via email at ko6bt@amsat.org, or via terrestrial mail to:

Duane Naugle, KO6BT
4111 Nemaha Drive
San Diego, CA 92117-4522
USA

Proceedings of the Symposium will be printed by the ARRL and made available at and immediately after the event. If authors do not wish to present a paper but have a topic of interest, please submit the topic and arrangements may be made for a stand-in presenter.

Receipt of submissions will be confirmed.

ISS Status

The second planned power test aboard the International Space Station was completed recently setting the stage for the arrival of the Shuttle Discovery on May 22nd, the first logistics flight carrying hardware and supplies to the outpost.

ISS also celebrated its fifth month in orbit.

Evaluation testing, also known as 'characterization' testing, of the station's two high-gain antenna was underway when communication was lost through the Early Communications System (ECS). The loss of communication is under evaluation, but a faulty transmitter box may be the culprit. A spare transmitter is already aboard the station and other spares are planned for delivery. In the meantime, communication and command is being conducted in the primary mode by Russian ground stations.

Space Shuttle Discovery rolled to its seaside launch pad earlier this week in preparation for the first flight of the year to visit the station. The transport of Discovery to the launch pad at the Kennedy Space Center in Florida sets the stage to deliver supplies that will be used by the first astronauts and cosmonauts to live on the outpost.

The next ISS component and the first full Russian contribution to the ISS program was rolled out of its testing plant recently. A certificate of flight readiness was signed signaling the official handover of the Service Module from RSC Energia Corporation to the launch processing team at the Baikonur Cosmodrome in Kazakhstan. It will be shipped by rail to the launch site from its initial manufacturing plant at the Krunichev State Research and Production Company. The official launch date will be determined once the module reaches Baikonur and assessments can be made on the remaining testing to be done.

The International Space Station remains in good health in an orbit with a high point of 252 statute miles and a low point of 238 statute miles, circling the Earth once approximately every 92 minutes. The station has completed 2,504 orbits of Earth since its launch.

Listeners to OSCAR-11 may be interested in visiting the G3CWV web site. The site contains details of the hardware and some software for capturing OSCAR-11 data and decoding ASCII telemetry and WOD. There is also an archive of raw data (mainly WOD) for analysis, which is continually expanded as new data is captured. Audio files are also included with examples of each type of data transmitted by the satellite (each one plays for about ten seconds). Examples of mode-S reception can also be found at the site. All the audio files are zipped so that they can be played off-line. The URL is http://www.users.zetnet.co.uk/clivew/

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

Uplink/downlink frequencies have not been established.

The satellite is not currently available for uplink transmissions.

Hans, ZS5AKV, reports that SunSat is still in the initial test stages and the command team will provide more information as it becomes available. General amateur radio service is planned for the near future.

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 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.
