AMSAT-UK Colloquium 2012 First Call for Speakers

Holiday Inn Guildford GU2 7XZ

Holiday Inn Guildford GU2 7XZ

The AMSAT-UK International Space Colloquium will be held on September 15-16, 2012 in Guildford.

The Colloquium attracts an international audience from across Europe as well as North America and the Middle East. Attendees range from the builders of the CubeSats and Nanosats, those who communicate through them and beginners who wish to find out more about this fascinating branch of the hobby.

It provides a rare opportunity to chat with satellite designers and builders, discussions frequently continue until the early hours of the morning.

A Gala dinner is held on the Saturday evening along with the fund raising auction.

This is the first call for speakers for the AMSAT-UK International Space Colloquium 2012 which, due to the Olympic & Paralympic Games, will be held this year on the weekend of September 15-16, 2012 at the Holiday Inn, Guildford, GU2 7XZ, United Kingdom.

This Colloquium will take place a few weeks before the planned launch of AMSAT-UK’s FUNcube-1 satellite carrying a 435/145 MHz linear transponder for SSB/CW communications.

AMSAT-UK invites speakers, to cover topics about micro-satellites, CubeSats, Nanosats, space and associated activities, for this event.

They are also invited to submit papers for subsequent publishing on the AMSAT-UK web site. We normally prefer authors to present talks themselves rather than having someone else give them in the authors’ absence. We also welcome “unpresented” papers for the web site.

We appreciate that it is not always possible to give a firm indication of attendance at this stage but expressions of interest would be appreciated.

Submissions should be sent *ONLY* to G4DPZ, via the following routes:

e-mail: david dot johnson at blackpepper dot co dot uk

Postal address at http://www.qrz.com/db/G4DPZ

AMSAT-UK also invite anyone with requests for Program Topics to submit them as soon as possible to G4DPZ. Invitations for any papers on specific subjects will be included in the future call. Likewise if anyone knows of a good speaker, please send contact and other information to G4DPZ.

MURSAT1 – A (Hacker) Space Art Project

This video shows a presentation on the mur.sat TubeSat MURSAT1 that was given at the Chaos Computer Camp on August 13, 2011.

A team of about 15 people around mur.at (Graz/Austria) have build their first Nanosatellite called MURSAT1, based on the Interorbital Systems TubeSat and developed further following their research. In 2012 MURSAT1 should be launched into a 310 km orbit.

The amateur radio TubeSat carries a camera and a microphone.  The command and control uplink is in the 145.9 MHz band and the downlink in the 435 MHz band. Further info at mur.sat wiki https://wiki.mur.at/sat/

Watch mur.sat – A (Hacker) Space Art Project – CCCamp 2011

This talk gives an overview of the project and the technical hacking done so far.

The team say Mursat1 itself will become our performer, taking self portraits with a camera, transmitting data about his position relative to earth by torquers, receiving and translating particle detection and collision with a piezo microphone, sending compressed audiodata for radio transmission on earth, hosting children’s wishes to become a shooting star themselves, counting.

Speaker: Bernhard Tittelbach, Christian Pointner

Location: Luftfahrtmuseum Finowfurt, Museumstr. 1, 16244 Schorfheide near Berlin, Germany

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,

Triton-1 and Triton-2

Dnepr_rocket_lift-off

A DNEPR Lift-Off

Triton-1 and Triton-2 are expected to launch in late 2012 on a DNEPR from Yasny together with UKube-1, Delfi n3Xt, Trio-Cinema 1 & 2 and other spacecraft using frequencies in the amateur satellite service.

They are 3U Cubesats and each carries a radio science mission that aims to test an experimental advanced AIS (Automatic Identification System) receiver.

Telemetry decoding software will be made available which will allow radio amateur operators to listen to periodic downlink broadcasts containing housekeeping telemetry, payload telemetry as well as received AIS messages.

Triton-1 telemetry downlinks will be 9k6 RC-BPSK on VHF(145MHz). It includes two similar secondary amateur radio payloads, being two single channel mode U/V (435-145MHz) FM to DSB transponders. The following downlink frequencies have been coordinated for Triton-1: Main Downlink 145.815MHz & Backup Downlink 145.860MHz. Possibly (power budget permitting), both transponders may be switched on at the same time.

Triton-2 telemetry downlinks will be 9k6 RC-BPSK on VHF(145MHz) and 38k4 RC-BPSK on S Band (2400MHz). The satellite includes two secondary amateur radio payloads:

– A single channel mode U/V (435-145MHz) FM to DSB transponder.
– A single channel mode U/S (435-2400MHz) FM to FM transponder.

The following downlink frequencies have been coordinated for Triton-2: Main Downlink 145.860MHz & Backup Downlink 145.815MHz. The S-band downlink will be 2408.00MHz. Possibly (power budget permitting), both payloads may be switched on at the same time.

Mission duration
Science mission: 3 Months
Amateur radio mission: as long as possible after the science mission finishes.
