ArduSat Open Source Ham Radio CubeSats

ArduSat

Australian Foundation radio amateur Jonathan Oxer VK3FADO is one of the designers of the two CubeSats ArduSat-1 and ArduSat-X which arrived at the ISS on Friday, August 9 UT.

The Arduino-powered satellites were transported to the International Space Station by the Japanese HTV-4 cargo vessel along with the PicoDragon and TechEdSat-3 CubeSats and the HamTV transmitter.

The ArduSat’s will be deployed from the ISS by the Kibo robot arm sometime between October 2013 and March 2014. They are expected to have a lifetime of 7 months before burning up in Earth’s atmosphere.

An article in The Register by Simon Sharwood says

Jonathan Oxer, one of the satellites’ designers, says serious science is one aim of the project, its main goal is “ is to inspire hobbyists and school students to learn about space technology, beginning with simple experiments using cheap Arduino boards in their classroom and then seamlessly transitioning to running those same experiments in space on a real satellite.”

That experience, he hopes, will see them take pursue studies in technical fields and over time address skills shortages.

Oxer hopes to release designs for the ASPPM.

“The design of the payload will also be released under the TAPR Open Hardware License, as soon as I have a clear path to do it without falling afoul of the laws restricting international arms trade [ITAR],” he told The Reg. “That’s actually quite a problem because satellite technology is classified as a weapon, no matter what its purpose is.”

The International Traffic in Arms Regulations (ITAR) were introduced by the US Federal Government. ITAR threatens US radio amateurs with up to six figure fines or jail if they talk to non-US citizens about certain aspects of their amateur satellite hobby. These draconian regulations have stopped cooperation on amateur satellite projects between US hams and the rest of the world.

The amateur radio group TAPR developed the TAPR Open Hardware License (“OHL”) to provide a framework for hardware projects that is similar to the one used for Open Source software  http://www.tapr.org/OHL

Among the other radio amateurs who’ve been working on ArduSat are Jeroen Cappaert KK6BLQ and Joel Spark KK6ANB, both hold the USA equivalent of UK and Australian Foundation licences.

In this video radio amateur Palle Haastrup OZ1HIA, President of Euroluna (OZ9LUNA), describes the Romit1 mission to space in pictures.

Euroluna are a Danish amateur team participating in the $30 million Google Lunar X PRIZE contest to be the first privately funded team to land and drive a rover on the Moon.

Their first amateur radio satellite Romit1 is a 2U CubeSat that will transmit on 437.505 MHz using 1200 bps AX.25 packet radio. It will be fitted with an Ion Motor and if everything goes well it should, after a year, be able to raise the orbit from 310 km to 700 km. It is planned to launch on an Interorbital Systems Neptune 30 rocket.

The CubeSats will be deployed from the ISS by the JEM Small Satellite Orbital Deployer (J-SSOD) between October 2013 and March 2014, they are:
•    PicoDragon a 1U CubeSat developed by Vietnam National Satellite Center (VNSC), University of Tokyo and IHI aerospace. 437.250 MHz CW beacon and 437.365 MHz 1200 bps AFSK AX.25 telemetry.
•    ArduSat-1 developed by NanoSatisfi. 437.325 MHz 9k6 MSK CCSDS downlink.
•    ArduSat-X developed by NanoSatisfi. 437.345 MHz 9k6 MSK CCSDS downlink .
•    TechEdSat-3 developed by interns at the NASA Ames Research Center. 437.465 MHz 1200 bps packet radio beacon transmitting 1 watt to 1/4 wave monopole. It plans to test an Iridium Satphone modem and has a deployment mechanism to de-orbit in 10 days.

They are 1U in size (10*10*10 cm) except for TechEdSat-3 which is 3U (30*10*10 cm).

The company NanoRack has announced it is sending 36 Units of CubeSats to the ISS (believed to be 26 separate CubeSats, some 2U or 3U in size). At the time of writing it is believed they will be going on a later cargo vessel.

The HamTV transmitter is the culmination of over ten years work to establish an amateur radio TV transmitter on the ISS. It will use patch antennas fixed on the Meteorite Debris Panels (MDP) protecting the hull of the ISS Columbus module. These antennas were installed while Columbus was being constructed. A fund-raising campaign took place during 2005-7 to raise over 65,000 Euros for the antennas. Individual radio amateurs from around the world donated generously as did several organisations such as AMSAT-UK and the RSGB.

The transmitter will be installed in the Columbus module in the coming months. It can transmit DVB-S signals on 2422.0 MHz or 2437.0 MHz at either 1.3 Msps or 2.3 Msps with 10 watts of RF output.

The main mission of HamTV is to perform contacts between the astronauts on the ISS and school students, not only by voice as now, but also by unidirectional video from the ISS to the ground.

In addition to school contacts the equipment is capable of transmitting other pre-recorded video up to 24 hours a day to allow ground stations tuning.

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
