The UK smartphone satellite STRaND-1 is expected to launch from India on Monday, Feb. 25 at 12:25 GMT. You can follow the launch on Twitter or watch live video.

STRaND-1 and other CubeSats carrying amateur radio payloads are planned to launch on the ISRO PSLV-C20 rocket into a 785 km orbit.

STRaND-1 carries an amateur radio 9600 bps AX.25 packet radio downlink on 437.568 MHz. It is hoping to be the first ever satellite to carry a smartphone into space and is also believed be the first satellite to use a part produced with a 3D Printer.

On Twitter the Surrey Space Centre @SpaceAtSurrey tweeted:

Official launch hashtag of STRaND-1 spacecraft is #S1Launch. Post launch we will be using #STRaND1 hashtag. Launch time:12.25 GMT 25th Feb 2013 #UniOfSurrey #SSTL

Launch Authorisation Board (LAB) for PSLV – C20 @STRaND mission has cleared the launch on Monday, Feb 25, 2013. @university of surrey #S1Launch

The launch rehearsal of PSLV-C20 with the primary satellite SARAL and six other satellites has been completed satisfactorily at SDSC SHAR, Sriharikota. Mission Readiness Review and meeting of Launch Authorisation Board are scheduled on Feb 22, 2013.

STRaND-1 is a joint mission between Surrey Space Centre at University of Surrey and Surrey Satellite Technology Ltd (SSTL). There will be an amateur radio AX.25 packet radio 9k6 bps downlink on 437.568 MHz and the launch is expected to take place on Feb 25.

An English language article about ShindaiSat is available at

https://directory.eoportal.org/web/eoportal/satellite-missions/s/shindaisat

ShindaiSatShindaiSat is a 20 kg spacecraft approx 300 by 300 by 350 mm which is planning to use bright LEDs for Space to Earth optical communication using Morse code. It also carries an optical lens system for receiving modulated LED light from the ground station.

There will be an AX.25 packet radio telemetry beacon and a low power CW beacon. Downlink frequencies of 437.305 and 437.485 MHz have been coordinated by the IARU Amateur Satellite Frequency Coordination Panel.

The article says “A launch of ShindaiSat as a secondary payload is manifested for mid-2014 on the primary GPM (Global Precipitation Measurement) mission of NASA and JAXA. JAXA is providing the launch on the H2A vehicle from the Tanegashima Space Center, Japan.

Orbit: Non-sun-synchronous circular orbit, altitude = 407 km, inclination = 65º.”
