Grupo de Radioaficionados para Operaciones Satelitales (GROS) Coordinator Raydel Espinet CM2ESP comments on the use of amateur radio satellites for emergency communications and describes how an amateur satellite was used in a Civil Defense exercise on May 18-19, 2013.

About the topic of satellites and emergencies I think satellites are an option very important to consider when there is no more available. In case of HF propagation blackouts or poor conditions and when local VHF and UHF repeaters fails, satellites can bring help, specially from light weight battery run portable stations.

FRC_CubaHere in Cuba we do every year an emergency rehearsal exercise named “Meteoro” which is organized by Cuba’s Civil Defense to simulate catastrophes and other actions relevant to the upcoming hurricane season.

This weekend (May 18th and 19th) was held the 2013 Exercise, like always Cuban Ham Radio Operators are invited to participate as an important asset during emergencies. But by first time ever on the Civil Defense National Headquarters were is installed amateur station CO9DCN we do a short and simple satellite demonstration to the Civil Defense authorities.

The short demo was just a simple “hello” exchanged between CO6CBF (Hector) in Cienfuegos Province and CM2ESP/Portable (Raydel) in the Headquarter’s backyard. Hector had done previous years demos for his province’s civil defense authorities, but this was the first time a demo was done at the National Civil Defense Headquarters. As HF propagation was terribly bad that day due to the recent solar flares the Civil Defense Authorities were very pleased with our short demo proving that satellites can be an alternative when ground and ionospheric propagation are disrupted.

The Press publish a short report about the amateur radio importance on emergencies and there is also a short mention in paragraph three of the very first satellite contact.

On the picture featured on the news report from the Cuban News Agency you can see CO9DCN Club Station (Defensa Civil Nacional – National Civil Defense) being operated by CO2OT in digital modes and CO2JC in voice communications. The satellite demo was done portable on the backyard on Sunday at 14:10 UTC during a SO-50 pass, the press arrived one hour after the satellite pass so unfortunately there is no photo available.

The hard work of the first two weeks has paid off and the CAM team, leaded by the University of Tartu Computer Technology graduate student Henri Kuuste has this to say: The camera works perfectly and so do all the other subsystems, needed for taking the photo. The first image was captured on May 15 over the Mediterranean Sea, showing the sea, Sahara desert, and Tunisia.

On Monday, May 13 the whole ESTCube-1 team was invited to the reception of the rector of University of Tartu to celebrate the success of the satellite. Watch the video (in English) at http://www.uttv.ee/naita?id=17163

ESTCube-1 was built by students at the University of Tartu. The main mission of the satellite is to test electric solar wind sail technology, a novel space propulsion technology that could revolutionize transportation within the solar system. It will deploy a 10 meter conductive electrodynamic tether and the force interacting with the tether will be measured.

The technology is based on the electrostatic interaction between the electric field generated by the satellite and the high-speed particles being ejected from the Sun. A spacecraft utilizing this method would first deploy a set of electrically charged wires, which allow to generate an electric field over a large area. This area effectively forms a “sail” that can be pushed by the charged particles by being diverted by it and therefore transferring momentum to the craft.

ESTCube-1 uses these frequencies:
437.252 MHz – CW beacon, callsign ES5E/S
437.505 MHz – 9600 bps AX.25 telemetry, callsign ES5E-11

The Guardian newspaper reports that Major Tim Peake has been selected to fly a five-month mission on the International Space Station (ISS) in 2015.

Tim Peake, from Salisbury in Wiltshire, was chosen for astronaut training in 2009 from 8,400 applicants. Since then he has been undergoing training in a number of locations around the world including Köln in Germany, Star City in Russia and Houston in Texas. He had previously served in the army for 18 years primarily flying Apache helicopters and has seen active service in Afghanistan.

The Guardian newspaper says: 41-year-old Peake has been assigned a lengthy stay in orbit in 2015. He will be blasted into space on a Russian Soyuz rocket from Kazakhstan in November that year and flown to the space station where he will stay for five months. He will be able to take part in spacewalks and other complex scientific activities.

NASA announced on May 13, 2013 that AMSAT’s Fox-1 amateur radio spacecraft has been assigned for launch in November 2014 on the ELaNa XII mission. The expected orbit is 470 x 780 km at 64 degrees inclination. This orbit has a lifetime of about 11 years.

AMSAT Vice President Engineering, Tony Monteiro, AA2TX, reported that the software development team successfully brought up the Fox-1 system software on the Internal Housekeeping Unit (IHU). The IHU is the brains of the Fox-1 satellite and it has a 32-bit, STM32L microprocessor. The operating IHU card was shown in the AMSAT Engineering booth at the Dayton Hamvention.

AMSAT FOXThe Fox-1 Engineering Team will deliver the satellite for integration with the launch vehicle during May, 2014 with the launch scheduled for November, 2014. Tony commented, “While this is later than we had hoped, it is well within the normal variance of ELaNa launch dates and the extra time will be most welcome for additional satellite testing. This is very exciting news and really puts the focus on finishing the satellite and ground station software development.”

President Barry Baines says, “AMSAT’s focus on STEM education and development of a CubeSat platform capable of flying a science mission with a reliable communications link resulted in the selection of Fox-1 in the third round and RadFxSat (Fox-1B) in the fourth round of NASA’s Cubesat Launch Initiative.”

All Fox CubeSats are designed to host advanced science payloads to support future science missions that help us to continue qualify for NASA ELaNa (free) launches. The Phase 1 Fox satellites are 1-Unit CubeSats. They each include an analog FM repeater that will allow simple ground stations using an HT and an “arrow” type antenna to make contacts using the satellite. This was the mode made so popular by AO-51. The Phase 1 CubeSats also have the capability of operating in a high-speed digital mode for data communications. Phase 2 Fox satellites will include software-defined-transponders (SDX) like the one tested on ARISSat-1. These will be able to operate in a wide variety of analog and digital communications modes including linear transponders. Since this requires more power for reliable operation, these will probably all be 3-Unit CubeSats.

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 announced for HamTV from the International Space Station

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

Italian astronaut Luca Parmitano KF5KDP is planned to launch from Baikonur in Kazhakstan to the ISS on May 28 (see High School Student’s RocketHub Project). 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.
