UoSAT-12 Launch Imminent

Chris Jackson, G7UPN, tells ANS that "UoSAT-12 is due to be launched aboard a converted Soviet SS-18 ICBM missile very soon." The launch, from the Baikonur Cosmodrome, could take place as early as the week of April 19th.

UoSAT-12 is the latest satellite from the University of Surrey. The amateur package was built by the University's UoSAT team as a research satellite (along the lines of UO-9, UO-11, UO-14, UO-15 and UO-22).

UoSAT-12 carries a number of imaging payloads (with up to 10-meter image resolution) along with digital store-and-forward communications in both the VHF and UHF band segments. Mode L/S transponders will also be supported with a high-speed digital downlink.

Chris reports the satellite is considerably larger than UO-22 or TO-31 and carries a propulsion system for orbital housekeeping experiments. The imaging system comprises a panchromatic imager and a multispectral imager along with a wide-angle color camera. The S-band downlink can run at speeds up to 1Mb per second for downloading imaging data, and can also be used as an L/S analog (voice) transponder. L/S frequencies are selectable via groundstation command.

Chris reports the L/S payload consumes "an awful lot of power", which means the transponder will be subject to on/off times following a published schedule.

UoSAT-12 will be placed into a 640km by 66-degree inclination orbit. During the initial orbits the satellite will be transmitting 9600 baud FSK telemetry framed in a VLSI format using a downlink frequency of 437.400 MHz.

G7UPN promises "more information in the form of regular postings as things progress to launch", telling ANS "there's still a lot of work to do and not much time to get it all done." In addition, a dedicated UoSAT-12 web site with more information will soon be available. In the interim, John, G0ORX, reports preliminary UoSAT-12 data can be found at:

14th AMSAT-UK Colloquium

Richard Limebear, G3RWL, has announced that the 14th AMSAT-UK Colloquium, also known as SpaceComm '99, will be held at Surrey University, Guildford, Surrey, United Kingdom. The Colloquium will  run from July 23rd through July 25, 1999.

AMSAT-UK invites authors to submit papers about amateur radio space and associated activities for this event and for the Proceedings document, which will be published at the same time. G3RWL reports they normally prefer authors to present papers, but also welcome unpresented papers for the event. AMSAT-UK also invites anyone with requests for program topics (especially topics for beginners) to submit them as soon as possible to G3RWL.

Offers of Papers should be submitted as soon as possible with the final date for full documents currently set as mid-June 1999 (in order that the Proceedings document is available to participants).

Submissions should be sent to G3RWL, via the following routes:

Internet e-mail:
Packet Radio:     G3RWL @ GB7HSN.#32.GBR.EU
Satellite:         Oscar 16/22/25

Terrestrial mail:

   R W L Limebear G3RWL
   60 Willow Road
   Enfield EN1 3NQ
   United Kingdom

AMSAT-UK will also be offering sessions specifically for satellite beginners. There will be two identical sessions during the event.

Colloquium booking information is expected to issue shortly.

National Volunteer Week

ARRL Headquarters has issued a hearty thank you and a tip of a ten-gallon hat to all amateur radio volunteers during National Volunteer Week, April 18-24, 1999.

According to the ARRL "our great hobby is even greater because of volunteer dedication and the many types of efforts they put forth. Volunteer activities start with planting the seed about amateur radio and continue in assisting with earning a license to encouraging a ham's interest in any and every aspect within amateur radio."

In the realm of public service, ham radio volunteers serve admirably to provide emergency communication and assistance of all types during disasters and emergencies everywhere. For disaster victims, amateur radio volunteers often have provided a link with the outside world when other systems failed, easing the plight of victims and helping affected communities to recover.

ANS would like to echo the League comments. AMSAT is truly a volunteer organization and could not exist without the dedicated efforts of many hardworking people. ANS alone receives weekly information from several satellite operators who help AMSAT News Service with news and information about our wonderful aspect of amateur radio. Without the activities of these volunteers, ANS would not exist!

ANS editor Dan James, NN0DJ, would like to thank each and every one of the many amateur radio satellite operators that help with this important task.

Downlink 145.825 MHz FM, 1200 baud PSK
Beacon 2401.500 MHz

Clive, G3CWV, reports during the period 16-March to 15-April-1999 good signals have been received from the 145.826 MHz beacon. The battery voltage during daylight passes has decreased (particularly towards the end of the reporting period). The average value is 13.6 volts, with 13.3 volts recorded on one occasion. A quick look at the current Whole Orbit Data (WOD) survey shows the battery voltage varying between 13.4 and 14.1 volts during sunlight, and a steady decrease to 12.3 volts during the eclipse period.

The internal temperatures have decreased slightly and are now 4.0C and 2.2C for battery and telemetry electronics respectively.

The operating schedule is unchanged.

ASCII status (210 seconds)
ASCII bulletin (60 seconds)
BINARY SEU (30 seconds)
ASCII TLM (90 seconds)
ASCII WOD (120 seconds)
ASCII bulletin (60 seconds)
BINARY ENG (30 seconds)

The ASCII bulletin is currently a static message, detailing modes and frequencies of all the amateur radio satellites. There are additional status blocks after each bulletin is transmitted, and between ASCII TLM and WOD.

The 2401 MHz mode-S beacon is on, transmitting an unmodulated carrier, but telemetry indicates that it has partially failed and is delivering half power output. Any reports of reception on 2401 MHz should be sent to

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

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. At this time the command team is planning general amateur radio service in 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.

For more information on SunSat, visit the following URL:

The satellite is not currently available for uplink transmissions. Recovery efforts have been unsuccessful.

SEDSAT-1, signifying Students for the Exploration and Development of Space Satellite number one, was successfully launched and placed in orbit on Saturday, October 24, 1998.

SedSat was last reported to be performing as it has since launch, transmitting telemetry until the batteries are depleted -- going into safe mode -- recharging batteries -- and then repeating the process.
