TechEdSat to use ‘SatPhone’

TechEdSat

TechEdSat

TechEdSat will be deployed from the International Space Station (ISS). It is a 1U CubeSat that will demonstrate Plug and Play power architecture and two way communication via the satellite phone/data networks Iridium and Orbcomm.

UPDATE: The plan to transmit from space using frequencies allocated to Iridium and Orbcomm SatPhone ground stations has been canceled. A statement from the team says: “We were forced to disable the Iridium modem as our FCC license did not come in time. As usual, building the satellite is the easy part.”

There will be a 437.465 MHz beacon transmitting 1 watt to 1/4 wave monopole. Commanding is via the commercial networks and there is a 2 week watchdog timer to stop the beacon in the event of no commands being received.

TechEdSat will be launched along with Raiko, FITSat-1, We-Wish and F-1 to the ISS aboard HTV-3, currently planned to launch July 18, 2012. From there, it will be deployed into Low Earth Orbit  using the JAXA J-SSOD deployer, from the Japanese Experiment Module (JEM also known as Kibo).

AMSAT-UK Satellite Talk at Telford

RSGB President Dave Wilson M0OBW Presents Louis Varney G5RV Cup to Paul Robinson 2E1EUB

RSGB President Dave Wilson M0OBW Presents Louis Varney G5RV Cup to Paul Robinson 2E1EUB

Paul Robinson 2E1EUB will be guest speaker at the Telford and District Amateur Radio Society (TDARS) on Wednesday, March 21, where he will give a talk about amateur radio satellites.

In 2011 the RSGB awarded Paul the prestigious Louis Varney Cup for Advances in Space Communication, which was presented to him at the Telford Hamfest.

Over the years Paul has worked hard promoting and encouraging the use of amateur radio satellites and perfecting the art of a portable ground station.

Amateur radio satellite communications can be achieved using very simple equipment. You don’t need high power or massive antennas.  If you want to find out more about this fascinating part of the hobby make sure you get to Paul’s talk.

The meeting starts at 7 pm on Wednesday, March 21 at Little Wenlock Village Hall, Malthouse Bank, Little Wenlock, Telford, TF6 5BG.

Nano and picosatellite resolution at WRC-12

RA-WRC-12-LogoWouter Jan Ubbels PE4WJ provides an update regarding the attendance by ISIS at the World Radiocommunication Conference.

At the conference, ISIS has managed to write a last-minute resolution which was submitted by a group of countries, led by The Netherlands. The aim of this resolution is to propose an agenda item for the next WRC (2015), which proposes to conduct studies to identify the spectrum needs of nano-and picosatellites, and furthermore to study the associated regulatory constraints. After the discussions at the WRC, the resolution got partially accepted by the conference (only the regulatory aspects will be studied), and not for the WRC-2015 but for the WRC after that, which will be in 2018. The provisional final acts of WRC2012 has been published, I quote:

“2.2 to consider the appropriate regulatory procedures for notifying satellite networks needed to facilitate the deployment and operation of nano- and picosatellites, in accordance with Resolution COM6/10 (WRC-12); ”

TIES users can download the provisional final acts at http://www.itu.int/md/R12-WRC12-R-0001/en

This is very good news, and could mean that the ITU notification process for nano and picosatellites can become greatly simplified in the future. We first of all would like to thank all the supporting administrations for their support and would like to invite the community to, through their administrations, participate in the studies, so that the outcome will be as much as possible line with the needs of the community.

We will continue to work on this subject and keep you updated through these lists and at the various small / nano / picosatellite conferences and workshops.

kind regards,

New MO-72 Decode Software

MO-72 Masat-1 Telemetry Decode SoftwareThe students who developed the amateur radio satellite MO-72 (Masat-1) have announced that new telemetry decode software is available.

Changes in this new release include:
– “Offline” label removed, the status of the automatic packet reporting is displayed
– Battery voltage constant (on the EPS panel) updated
– Now you can change between 626/1250 bps decoding on the Packets panel
– On the frequency waterfall now you can see tracks for the 0, CW and 1. The decoder is the most sensitive if the signal is in the middle of the highlighted track

Download the new software from http://cubesat.bme.hu/en/radioamatoroknek/kliens-szoftver/

OSCAR Number Administrator Bill Tynan, W3XO reports,
“Congratulations on the successful launch of the MaSat-1 Cubesat that the team at Budapest University of Technology and Economics have been responsible for designing, building and testing.

“Since you have met all of the requirements for being issued an OSCAR number, including coordination through IARU and requesting an OSCAR number, I, under authority vested in me by the President of AMSAT-NA, do hereby name MaSat-1 as MagyarSat-OSCAR-72 or MO-72.”

Bill concludes, “I, and all at AMSAT-NA wish MagyarSat-OSCAR-72 great success in fulfilling all of its mission objectives.”
