November Deployment for ISS CubeSats

Four CubeSats carrying amateur radio payloads are expected to be deployed from the International Space Station (ISS) by the JEM Small Satellite Orbital Deployer (J-SSOD) on November 25, 2013.
The CubeSats are:

• Pico Dragon developed by the Việt Nam 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).

WREN was built by four guys in a garage !!

We are four guys in a garage, and we have dedicated ourselves to open space for everyone. For that purpose we designed the miniaturized satellite WREN. It’s a so called Pocketqub-Femtosatellite. It has only 5x5x5cm³ of volume and 250g of mass, and fits perfectly into your hand, like a tennis ball. Despite of its size, it even has real thrusters.

 The tiny PocketQube satellite, aims to transmit amateur radio Slow Scan TV (SSTV) pictures using the Martin-1 format.

Despite its small size WREN is equipped with a camera, a gyro, a magnetic field sensor, momentum wheels and pulsed plasma micro-thrusters. The camera is equipped with an image processing system which can find the position of the Sun and the Earth automatically.
The communications uplink and downlink will take place on the IARU coordinated frequency of 437.405 MHz.
WREN is flying inside a larger satellite called UNISAT-5 that will be launched in late November, 2013 on a Dnepr rocket from Dombarovsky near Yasny. UNISAT-5 should deploy WREN one month later, so we may expect to receive the SSTV signal in January 2014.

NASA Laser Communication System Sets Record with Data Transmissions to and from Moon

NASA’s Lunar Laser Communication Demonstration (LLCD) has made history using a pulsed laser beam to transmit data over the 239,000 miles between the moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps).
LLCD is NASA’s first system for two-way communication using a laser instead of radio waves. It also has demonstrated an error-free data upload rate of 20 Mbps transmitted from the primary ground station in New Mexico to the spacecraft currently orbiting the moon.
