AMSAT UK Shop under new management

After several years of running the AMSAT-UK shop, Jim G3WGM has handed the reins to Ciaran Morgan M0XTD. Ciaran obtained his full license in April 2008 and enjoyed organising a very successful ARISS contact between Budbrooke School in Warwick, England and Richard Garriott K5KWQ whilst he was onboard the International Space Station in October 2008.

AMSAT-DL Press Release

First German Mars Mission makes sidestep to Venus, Ground station in Bochum generated echoes from Venus The team of German Space Agency AMSAT-DL reached another milestone on the way to send a spacecraft to Mars on 25 March 2009. From ground mission control station in Bochum (located in the observatory IUZ Sternwarte) radio frequency signals were sent to Venus.

Listen for New Sats using Web Receiver

You can listen for the new Amateur Radio satellites, launched Friday Jan 23, by using a Web based Software Defined Radio (SDR). Some of the Radio Amateurs who were involved in the very successful Delfi-C3 / DO-64 Amateur Radio satellite have made available a WebSDR receiver that listeners around the world can use to receive signals from the new Amateur Radio satellites.

Hokkaido Institute of Technology CubeSat

Hokkaido Institute of Technology’s HIT-SAT satellite has joined several other CubeSats carrying Amateur Radio payloads in space. The tiny satellite launched successfully September 23 (Japan Standard Time) from the Uchinoura Space Center in Japan, and its CW telemetry was copied around the world on the satellite’s initial orbits. Over the weekend, HIT-SAT’s CW telemetry was halted as a power-saving measure during attitude control procedures, and it remained silent after attitude control should have ended. But on September 27, ground controllers were able to restore the CW telemetry.

“Although the cause was still unknown, we hope the transmission of CW continues normally,” the HIT-SAT team said on its Web site. “We appreciate the cooperation and help of radio amateurs all over the world. Please hear the beat of our satellite’s heart.” HIT-SAT’s FM packet transmitter has been operating normally from the time the spacecraft reached orbit, and ground controllers have been able to obtain telemetry data from it.

Like other university-built CubeSats, HIT-SAT was constructed using mostly off-the-shelf parts. The 1200 bps FM packet downlink is on 437.425 MHz, while the CW telemetry downlink is on 437.275 with a transmitter power of 100 mW. The CubeSat uses a VHF uplink. The HIT-SAT team is seeking reception reports, including audio files. The satellite’s call sign is JR8YJT.

Once it’s fully operational, HIT-SAT will permit Earth station operators to request certain parameters by transmitting DTMF commands on the 145.980 MHz uplink. The satellite can report back time/date, temperature and power supply voltages and thank the Earth station by call sign. Only HIT-SAT ground station controllers can access the satellite at this point, however.

The diminutive satellite is a project of the Hokkaido Institute of Technology’s ham radio club. HIT-SAT hitchhiked on the M-V-7 vehicle that carried the Solar-B satellite into orbit. The satellite is in a sun synchronous orbit with an orbital altitude of 250 km at perigee and 600 km at apogee and an inclination of 97.79 degrees. A 12-cm square cube, HIT-SAT weighs 2.2 kg.

AMSAT Project Eagle

AMSAT-NA has announced it’s revamping the design of its high-Earth orbit (HEO) Project Eagle satellite, currently in the development stages The next generation satellite will take maximum advantage of software-defined transponder (SDX) technology to offer a broader range of easily accessible Amateur Radio payloads. The AMSAT Board of Directors okayed the Eagle upgrade plans during the 2006 AMSAT-NA Space Symposium and Annual Meeting held October 6-8 in San Francisco. Eagle Project Manager Jim Sanford, WB4GCS, outlined the changes at his Space Symposium forum October 7.

“The structure which we have been presenting for several years is not going to meet our mission needs,” Sanford explained. “We have moved on to a later structure.”

Under the new plan, Sanford says, Eagle’s communications payloads will include a mode U/V linear transponder for SSB, CW and other modes. A second SSB/CW transponder will uplink on L band (1.2 GHz) and downlink on S1 band (2.4 GHz). Both would be usable over 75 percent of the satellite’s orbit by an AO-13 or AO-40-capable ground station, AMSAT says.
