HAMSAT VO-52 Activation Planned For Wednesday

HAMSAT VO-52

HAMSAT VO-52

Mani VU2WMY reports that due to ‘Operational Constraints’ the commands to turn on the Dutch SSB/CW transponder on HAMSAT (VO-52) could not be sent on Tuesday and attempts at 01:44 UT and 03:20 UT Wednesday were unsuccessful.

The next attempt will be made during the 14:00 UT pass over India.

William Leijenaar PE1RAH, designer and builder of the Dutch SSB/CW linear transponder on HAMSAT (VO-52), requests reports when the transponder is activated. He says:

! ! !  Please don’t use high uplink powers !!! (We don’t want it to rise temperature very fast just after cold switch on) ! ! !

Please listen for the CW beacon at 145.860, which is a good reference.
(Audio records and reports are very welcome at ISRO and myself)

73 de PE1RAH,
William Leijenaar

The frequencies used will be:

Uplink:         435.2250 – 435.2750 MHz SSB/CW
Downlink:     145.9250 – 145.8750 MHz SSB/CW
Beacon:       145.8600 MHz CW

New Amateur Satellite Frequency Coordination Request Form

IARU Satellite Advisor Hans van de Groenendaal ZS6AKV has made available a new version of the Amateur Satellite Frequency Coordination request form.

Frequency coordination for amateur radio satellites is provided by the IARU through its Satellite Advisor, an official appointed by the IARU Administrative Council, its top policymaking body.

The IARU Satellite Advisor is assisted by an Advisory Panel of qualified amateurs from all three IARU Regions. The panel meets regularly via Skype to consider amateur satellite frequency coordination requests for satellites planned for operation on frequencies in the amateur service. The panel members often provide advice and assist satellite builders with the selection of   the best possible frequencies to meet the objectives of their mission.

The Amateur Satellite Frequency Coordination request form has been updated (Version 27) and is available for download from http://www.iaru.org/satellite.

On the IARU web satellite page there are also available a number of guideline documents which will assist satellite builders, including a document on the ITU requirements for Amateur Radio Satellites.

ESA to start mini space mission series

BBC Science correspondent Jonathan Amos reports that the European Space Agency is starting what it expects to become a regular series of small science missions.

The first winning “S-Class” idea will receive 50 million euros (£42m) and will be readied for launch in 2017.

Prof Mark McCaughrean, head of ESA’s Research and Scientific Support Department is reported as saying:

“We want to hear from innovative people who’ve got a clever idea that doesn’t need a billion or half a billion euros, but can be done with a much smaller amount.”

GOMX-1 to test CubeSat Space Protocol

GOMX-1 is a student built amateur radio 2U CubeSat. The mission is being flown under the auspices of a Government research grant covering space related radio research. It will qualify a number of subsystems and provide extensive in-flight data.

A large number of future amateur/educational CubeSat missions depend on the important data that will be generated by this mission. This will help these mission teams across the globe to achieve higher reliability and improved utilization.

The mission will also test the use of the open source Cubesat Space Protocol (http://code.google.com/p/cubesat-space-protocol/) for a complete mission including the space link.

A camera payload will take color images of the Earth and an experimental Software Defined Radio receiver will be carried and its performance characterized.

More than 15 students at Aalborg University have been actively involved in the development of this payload as part of their semester projects.

It is planning to use GMSK telemetry with selectable 1k2/2k4/4k8/9k6 rates on UHF with approx 28dBm power to a deployed antenna. Launch is expected in late 2012 into a near sun syncronous orbit on a DNEPR rocket from Yasny in Russia with a number of other amateur radio satellites,  see Gunter’s Space Page http://space.skyrocket.de/doc_chr/lau2012.htm

Howard Long G6LVB featured speaker at AMSAT/TAPR Banquet

Howard

Howard Long G6LVB

The AMSAT/TAPR Banquet on Friday night, May 18 is one of the main AMSAT activities during the 2012 Hamvention at Dayton.

AMSAT-NA is pleased to announce that Howard Long G6LVB will be the featured speaker for the evening event. Howard will be talking about his  FUNcube Dongle, the 64 – 1700 MHz Software Defined Receiver.

This innovative USB device is the size of a thumbdrive and has an SMA antenna socket. Multiple SDR control and display software programs can be used with the FUNcube Dongle.

Banquet tickets will not be sold at the AMSAT booth during the Hamvention so reservations must be made through the AMSAT-NA Store http://www.amsat-na.com/store/item.php?id=100158
Tickets are $30 apiece.

Thanks to Gould Smith, WA4SXM for the above information

AMSAT-UK Net Recorded via 20 km WiFi Link (March 11th)

AMSAT-UK Net Recorded via 20 km WiFi Link

Simon Brown HB9DRV in Switzerland has made available a recording of Sunday’s AMSAT-UK 80m net that he made using a remote receiver in Poole, Dorset. What is remarkable about this recording is that a 20 km long experimental 2.4 GHz WiFi link was used at the Dorset end.

The AMSAT-UK net is held every Sunday morning at 10am local time on a nominal frequency of 3.780 MHz. Due to interference the net may move either side of that frequency so tune around. Newcomers are most welcome to call-in.

Listen to the AMSAT-UK Net recorded Sunday, March 11th, 2012. Due to the experimental nature of the 20 km WiFi link there are a few breaks in the recording.
