One of the most frequently asked questions from newcomers to amateur satellites must be “Which satellites can I receive?”

Mike Rupprecht DK3WN has produced a summary of all active amateur radio satellites with frequencies and links to more detailed information. It is available at  http://www.dk3wn.info/p/?page_id=29535

Tiny Satellites’ Big Mission: Going Beyond Earth Orbit

TechNewsDaily contributor Rachel Kaufman interviewed James Cutler KF6RFX about two CubeSats that aim to travel into interplanetary space.

The two Interplanetary NanoSpacecraft Pathfinder In Relevant Environment (INSPIRE) satellites measure just 10x10x30 cm and each weigh under 4kg.

The dual INSPIRE CubeSats will demonstrate functionality, communication, navigation and payload hosting in interplanetary space. INSPIRE is a NASA JPL partnership with the University of Michigan, Ann Arbor; Cal Poly San Luis Obispo; and the University of Texas at Austin, in collaboration with Goldstone-Apple Valley Radio Telescope.

Several CubeSats carrying amateur radio payloads are planned to launch on the Antares-110 mission in April.

On the CubeSat mailing list Jason Andrews President and CEO of both Spaceflight Inc and Andrews Space posted:

Spaceflight Inc recently completed CubeSat integration activities for the Antares demonstration mission including deployment dress rehersal.  Spaceflight has two ISIPod deployers on this mission.  One contains three 1U spacecraft for NASA Ames Research Center and the other contains a 3U spacecraft for a commercial customer.  An image of the integration activity can be found here:

Among the amateur radio CubeSats on the launch are three Phonesats which will all carry Google Nexus smartphones similar to the pioneering UK smartphone satellite STRaND-1 that was launched in February. There will be two PhoneSat 1.0’s and one PhoneSat 2.0 on the launch.

PhoneSat 1.0 cost about $3500 and is built around the Nexus One smartphone, it operates on battery power only with a mission lifetime of approx 1 week.

PhoneSat 2.0 is more expensive at $8000. It is built around the Nexus S smartphone and has solar panels on each face and a mission lifetime until de-orbit of approximately 2 weeks.

The IARU amateur satellite frequency coordination panel have coordinated frequencies of 437.425 MHz and 2401.2-2431.2MHz for the PhoneSats.

Also on the launch is the Dove-1 CubeSat. The Antares-110 launcher is expected to deploy the satellites into a 250 km 51.6° inclination orbit.

Two TV CubeSats from Ecuador

Ecuador is hoping to have two CubeSats in orbit this year.

Their first CubeSat NEE-01 Pegasus will carry a 720p HD camera to send live video from space using a 0.9 watt TV transmitter in the 910 MHz (33cm) band along with a beacon that will send a Morse Code ID, a SSTV image and Ecuador’s national anthem. It was originally planned to launch on a Dnepr from Yansy but is now expected to fly on a CZ-2D rocket from the Jiuquan Space Center on April 26, 2013 at 0413 UT.

Ecuadors second CubeSat NEE-02 Krysaor carries the same payloads in the 910 MHz band as NEE-1 Pegasus but has a slightly different solar panel configuration. As yet websites such as Gunter Space Page give no indication on which rocket NEE-02 Krysaor will fly.

Data Format for Korean OSSI CubeSat

Open Source Satellite Initiative Korean CubeSat OSSI-1Information has been released on the data format to be used by the Open Source Satellite Initiative (OSSI) CubeSat developed by Hojun Song DS1SBO.

The OSSI Data Format spreadsheet can be seen at https://docs.google.com/spreadsheet/ccc?key=0AjtQ6cJ4QOqJdGpHNnRtUWZJV0w4TTFKRU9WYTZqc3c#gid=5

OSSI-1 is planned to launch April 19, 2013 into a 575 km 63° inclination orbit on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1 satellite and the SOMP, BEESAT 2, BEESAT 3 and Dove-2 CubeSats. The OSSI VHF beacon is understood to be using 12 WPM CW.
