Kickstarter project aims to put a TARDIS into Low-Earth-Orbit

Kickstarter Dr Who TardisNovember 23, 2013 is the 50th anniversary of Doctor Who and a Kickstarter project aims to celebrate the event by putting a 30 cm (12 inch) tall model of the TARDIS into Low-Earth-Orbit on an Interorbital Systems Neptune rocket. The aim is to raise the $33,000 needed for the flight by June 29.

A number of satellite projects have already raised funds through Kickstarter but none has been quite like this. The orbiting TARDIS plans to have solar cells to power the flashing light, a camera and transmitter. A magnetic, passive attitude control system will keep the TARDIS’s camera pointing toward the Earth.

These satellite projects have already raised money on Kickstarter:

Radio ham Zac Manchester KD2BHC used Kickstarter to raise $74,586 in donations to fund the development and deployment of 200 amateur radio KickSat sprite satellites.

The amateur radio satellite project ArduSat managed to raise donations of $106,330 in just 30 days.

SkyCube which will transmit on 915 MHz in the 902-928 MHz amateur radio band raised $116,890.

Kickstarter is not just about raising large sums of money, for example Sandy Antunes used Kickstarter to raise $2,780 to buy a ham radio transceiver and antennas to create an amateur radio satellite ground station Calliope

IARU Coordinates Frequencies for Fox-1A Ham Radio CubeSat

AMSAT FOXThe International Amateur Radio Union (IARU) Frequency Coordination Panel has announced coordinated frequencies for the AMSAT-NA Fox-1a CubeSat.

A 1U CubeSat, Fox-1a will serve as a communications relay for radio amateurs worldwide via the onboard FM repeater system. It will also carry an experiment consisting of a 3-axis MEMs gyro developed by Penn State University. The communications and experiment missions will run concurrently.

The uplink will be on 435.180 MHz for FM voice and the downlink on 145.980 MHz with FM voice and an optional sub audible FSK digital carrier channel. Fox-1a will employ passive magnetic stabilization.

Fox-1a is planning to launch from Vandenburg in November 2014 on the NASA ELaNa XII mission with ARC1, BisonSat, Lightsail and R2S (NEO). The expected orbit is 470 x 780 km at 64 degrees inclination giving an orbit lifetime of about 11 years.

AMSAT Field Day 2013

Saudisat SO-50

Saudisat SO-50

The AMSAT-NA site reports on satellite activity for this years ARRL Field Day which takes place June 22-23.

Every year AMSAT promotes a satellite version of Field Day during the ARRL annual operating event which is held on the 4th weekend in June. This year Field Day will take place from 1800 UTC on Saturday June 22, 2013 through 2100 UTC on Sunday June 23, 2013.

SaudiSat-Oscar-50 will be the only operational FM transponder satellite this year. If you are considering only FM voice operating for your AMSAT Field Day focus the single uplink/downlink channel will be extremely challenging. As in prior years, this intense congestion on FM LEO satellites drives the limitation in the rules allowing their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. You will also be allowed one digital QSO with the ISS or any other digital, non-store-and-forward, packet satellite (if operational).

If you have worked the satellites on Field Day in recent years, you may have noticed a lot of good contacts can be made on the linear transponder satellites including VO-52, FO-29, and AO-7. During Field Day the transponders come alive like 20 meters on a weekend. The transponders on these satellites will support multiple simultaneous SSB or CW contacts.

The AMSAT Field Day 2013 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital.

For the complete listing of the AMSAT Field Day Rules please refer to the documents posted on-line at:

UK’s SpaceKate Wins ‘Most Inspiring App’ – International Space Apps Challenge

SpaceKate T-10 AppThe App produced by broadcast journalist Kate Arkless Gray a.k.a. SpaceKate has won the Most Inspiring App category of the International Space Apps Challange.

Radio amateur and former ISS Commander and Chris Hadfield VA3OOG said about the App “Cool idea! A 10-minute alarm would be perfect”.

The app was initially produced over a busy weekend at Space Apps London and consequently won a place in the international judging. The small team, which consists of Kate Arkless Gray, João Neves, Ketan Majmudar and Dario Lofish have continued to develop the app and provisionally hope to launch it in July. Getting the app into the hands of the astronauts may take a little more time, but that is the aim.

ANTELSAT a Ham Radio SSTV CubeSat from Uruguay

ANTELSAT CubeSat

ANTELSAT CubeSat

ANTELSAT is a 2U CubeSat class satellite with a 70 cm SSTV downlink and amateur radio AX.25 Digipeater that is planning a Yasny Dnepr launch in November, 2013. It has been developed by ANTEL (the national telecom service provider) and Facultad de Ingeniería de la Universidad de la República (FING), the State Faculty of Engineering.

The purpose is to build and operate the first satellite ever launched into orbit by Uruguay. Its goal is to develop skills in radio and aerospace engineering, to promote enthusiasm in STEM education at all levels, and provide challenging activities for undergraduate students. The spacecraft is planned to transmit colour and infrared images of the surface of the earth, and to provide several services to radio amateurs (AX.25 digipeater, telemetry beacon, uplink signal report, SSTV downlink). The mission is purely experimental and a technology demonstrator of all the satellite subsystems, which have been custom designed locally.

Communications:
– VHF receiver on 2m amateur band, 1200bps AX25 protocol.
– Telecommand uplink.
– Store and forward (digipeater) service uplink.
– UHF transmitter on 70cm amateur band:
– CW beacon.
– Telemetry downlink at 1200 bps AX25 protocol.
– Backup downlink for image data via low resolution SSTV.
– Store and forward service downlink.
– S-band transmitter on 2.4 GHz:
– Downlink for payload image data.
– Telemetry backup link.
– 2 redundant transmitters.

Attitude control:
– Attitude determination via magnetometer and photodetectors.
– Active 3-axis control via magnetorquers.

It is reported that ANTEL contributed nearly $700,000 towards the project
