On July 23, 2013 at 1634 UT Mike Rupprecht DK3WN received signals from the UK STRaND-1 satellite after a near four month absence.

Built by volunteers from the Surrey Space Centre (SSC) and SSTL in Guildford STRaND-1 was launched on February 25, 2013 and was the World’s first Smartphone CubeSat to be put into orbit.

STRaND-1 unexpectedly stopped transmitting on March 30, 2013 and radio amateurs around the world have been listening for it ever since on a frequency of 437.568 MHz (+/- 10 kHz Doppler).

Radio amateurs are requested to email reports of reception of telemetry data from STRaND-1 to: strand.messages<at>gmail.com

Mike Rupprecht DK3WN has been working on new software which compares the magnetometer values sent by STRaND-1 in comparison to the NOAA World Magnetic Mode (WMM2010). Further information at http://www.dk3wn.info/p/?p=31826

Surrey Space Centre report that the STRAND-1 satellite is healthy and in the coming weeks they hope to be able to switch-on the Google Nexus One smartphone carried by the CubeSat.

STRaND-1 Update – Ground Station Improvements Underway

STRaND-1 Ground Station Antennas

STRaND-1 Ground Station Antennas

Surrey Space Centre report that the STRAND-1 satellite is healthy but they have had new ground station teething problems. That has diverted effort and delayed the eagerly awaited switch-on of the Google Nexus One smartphone carried by the CubeSat.

The team are currently scouting University of Surrey rooftops for a better antenna position for STRaND-1.

The STRaND-1 downlink frequency is 437.568 MHz using 9k6 bps AX.25 packet radio. Details of the telemetry format are at https://amsat-uk.org/satellites/strand-1/strand-1-telemetry/

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
