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.
