MAREA: Ham Radio Robotics

An ARRL article describes the Mars Lander Amateur Radio Robotics Exploration Activity.

NASA has been doing some exciting explorations of Mars with robots, currently Opportunity and Curiosity, which are maneuvered on the Martian surface by remote control.  

These robots collect and analyze soil samples and relay the results of these distant experiments back to Earth. While students can learn about these experiments in newspapers, scientific journals, on the Internet or TV, wouldn’t a more active approach provide a more engaging learning experience? Why not let students experience the same thrills as the NASA scientists and engineers through a simulation that they conduct in their own classrooms?

The basic concept of MAREA uses robotic movement commands that are attached in the text portion of an Automatic Position Reporting System (APRS) packet transmission. The APRS packet with the attached commands is sent from a “mission control” school via the terrestrial APRS network or, when possible, even via the Amateur Radio station on the passing International Space Station (ISS), to a “ground station” school. At the ground station school the command packet is received and the command data is linked by UHF radio to the “Mars” robot for execution.

The MAREA system components consist of:
• the typical 2 meter packet capable ham radio transceiver (or receiver if reception only is desired)
• a computer running a free APRS packet display program, sound card TNC (Terminal Node Controller) and serial loopback software packages
• UHF data link transceivers
• an instructional robot

Fox-1 has a Launch Date!

AMSAT FOX

AMSAT FOX

NASA announced Monday that AMSAT’s Fox-1 FM transponder spacecraft has been assigned a launch in 2014. For details on the launch vehicle, targeted launch date, orbit specifics, and more, please attend the AMSAT Forum and visit the AMSAT booth at the Dayton Hamvention this weekend.  Watch http://www.amsat.org/ and the AMSAT News Service for more details to follow as they become available.

AMSAT’s Fox-1 CubeSat aims to provide these features:

• Fox-1 is designed to operate in sunlight without batteries once the battery system fails. This applies lessons learned from AO-51 and ARISSat-1 operations.

• In case of IHU failure Fox-1 aims to continue to operate its FM repeater in a basic, ‘zombie sat’ mode, so that the repeater remains on-the-air.

• Fox-1 is designed as the immediate replacement for AO-51. Its U/V (Mode B) FM transponder will make it even easier to work with modest equipment.

• From the ground user’s perspective, the same FM amateur radio equipment used for AO-51 may be used for Fox-1.

Frequencies have been announced for the new Ham Radio Digital TV transmitter that will send video from the ISS in the amateur radio 2400 MHz band.

The main mission of HamTV is to perform school contacts between the astronauts onboard ISS and the scholarship, not only by voice, but also by unidirectional video from the ISS to the ground within the ARISS program.

In addition to the existing VHF radio amateur station, ISS will host a S-Band video transmitting station. This new equipment can broadcast images from the ISS during the school contacts or other pre-recorded video images up to 24 hours a day to allow ground stations tuning.

It is planned to transmit DVB-S signals on 2.4GHz at either 1.3Msps or 2.3Msps with 10 watts of RF from the ISS Columbus module.

The IARU Amateur Satellite Frequency Coordination Panel have announced frequencies of 2422.0 MHz and 2437.0 MHz.

HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the name of the complete system, comprising DATV downlink and VHF voice uplink. Kaiser Italia SRL was the prime-contractor for the design and development of the flight and ground segment http://www.kayser.it/index.php/exploration-2/ham-tv

It is understood that the HamTV equipment will be carried to the ISS on the Japanese HTV-4 spacecraft currently planned for a launch on August 4.

British Interplanetary Society President to speak at AMSAT-UK Space Colloquium

Holiday Inn Guildford GU2 7XZ

Holiday Inn Guildford GU2 7XZ

The 2013 AMSAT-UK International Space Colloquium will start late afternoon on Friday, July 19 and will run through until the afternoon on Sunday, July 21 at the Holiday Inn, Guildford, GU2 7XZ, UK.

It will be preceded by an exciting “Hands-on” CubeSat Workshop which will take place at the nearby University of Surrey on the Friday and this will be followed, at the hotel, by the usual Colloquium “Beginners Session” in the late afternoon.

A number of keynote presentations have already been arranged for the Colloquium. These include Alistair Scott, the President of the British Interplanetary Society. The BIS has, over many decades, developed ideas and concepts about the future of space travel and both Patrick Moore and Arthur C Clarke were members. Alistair has had many years experience working in the space industry and will be reviewing the future possibilities for ventures into space both small and large. The BIS is presently developing one of the Sprites for the Kicksat mission and Andrew Vaudin will be presenting a paper about this and also providing a demonstration.

It is anticipated that both the FUNcube-1 and FUNcube-2 missions will be launched later this year and the FUNcube team will be on hand to talk about the missions and the planned educational outreach. A full demonstration of the Engineering Model, which has been performing flawlessly for almost a year, will also be provided.

On the Sunday, the General Manager of the RSGB, Graham Coomber, G0NBI will be talking about the Society’s vision of the future of amateur radio and how amateur satellites can play a major part in helping to secure that future.

We will also have updates on a number of the other current amateur satellite projects including HAMtv from the ISS, spectrum matters, operating methods, new products etc.

High School Student’s RocketHub Project

Abby Harrison - Astronaut AbbyFifteen-year-old Abigail Harrison has a big dream, to be the first astronaut to Mars.

She is currently using the crowd funding website RocketHub to raise money to fund a trip to Baikonur in Kazhakstan to watch her mentor, Astronaut Luca Parmitano KF5KDP, blast-off to the International Space Station at the end of May.

Almost two years ago, on the way home from the final launch of STS 134 Endeavour space shuttle, Abby met and interviewed Italian astronaut Luca Parmitanoo. Luca agreed to become her mentor, and for the last couple of years, he has stayed in touch and offered advice.

On Friday, April 26 Abby took part in a Google+ hangout with Luca KF5KDP, she writes:

The interview was facilitated by the Public Insight Network which is a part of American Public Media. I was so excited to have this opportunity with Luca before he launches on May 28, 2013  to live on the International Space Station (ISS) for six months. We had an awesome chat about both of our passions for space and STEM (science, technology, engineering, and math) as well as about Luca’s exciting work on the ISS this year.

We also discussed my exciting opportunity to serve as Luca’s Earth Liaison. In the chat, Luca talked about meeting me for the first time, saying, “I like passionate people. Any kind of passion. Any kind of interest in anything that keeps you inspired…I saw a lot of myself in Abby.” He emphasized his excitement and the importance of my job as Earth Liaison and that he was happy his experience could be used to inspire kids throughout the world.

Ofcom 2400 MHz Consultation

AMSAT-UK_Bevelled_LogoThe UK communications regulator Ofcom has published a call for inputs relating to spectrum use by licence exempt devices in the 2.4 GHz band. 2400-2450 MHz is an ITU Amateur and Amateur Satellite Service allocation.

The Ofcom announcement says:

This band is close to radio spectrum in the 2300 MHz band, which the Ministry of Defence (MoD) plans to release for new civil uses.

The MoD has therefore commissioned work to audit licence exempt uses in the 2400 MHz band, in particular to identify the full range of possible uses of this spectrum. The call for inputs introduces two audit reports that explore licence exempt use in the 2400 MHz band.

It also invites stakeholders to identify any other uses that may need to be considered to understand any technical coexistence.

The public consultation closes on June 19, 2013.
