BBC: ‘Pocket spacecrafts’ to become a reality

On Thursday, May 15, the BBC Radio 4 Today show featured an item on the recently launched 437 MHz Sprite satellites and the new Pocket Spacecraft being developed by a UK radio amateur.

The tiny Sprite satellites, measuring 3x3cm and just a few millimetres thick, contain a 437 MHz transmitter, solar cell, sensor and antenna. The CubeSat KickSat-1 carrying 104 Sprites was successfully launched on April 18, however, a suspected radiation glitch meant they could not be deployed before the CubeSat burnt up on re-entry on May 14.

UK radio amateur Michael Johnson M0MJJ has developed Pocket Spacecraft known as ‘Scouts’. A ‘Scout’ is a wafer thin disk with flexible electronics, smaller than a CD, containing a transceiver, antenna and solar cells. It is hoped to carry them in a CubeSat which would deploy them in Lunar orbit. It is understood that frequencies in the 435 MHz and 2400 MHz bands may be used.

Listen to the BBC Radio 4 clip ‘Pocket spacecrafts’ to become a reality in which BBC Click’s Spencer Kelly discusses the development of pocket spacecrafts http://www.bbc.co.uk/programmes/p01z4q22

It is expected that Pocket Spacecraft will feature in the BBC TV technology show ‘Click’ due to be released online on Saturday, May 17 at http://www.bbc.co.uk/programmes/b006m9ry

LituanicaSAT-1 Update May 14, 2014

The LituanicaSAT-1 team have provided a further update on their CubeSat which was deployed from the International Space Station (ISS) on February 28.

LituanicaSAT-1 FrequenciesDear radio amateurs,

As most of you have already noticed, since May 12 the satellite has been set up to nominal operational mode permanently with noticeable 9k6 baud packet telemetry on 437.544 MHz every 30s. However  next day on May 13 a telemetry report from W7KKE has shown that a latchup has been detected on 3.3 V1 EPS channel.

This channel is providing power for CW FM beacon and photo camera. Furthermore following reports from W7KKE and LU4EOU have shown that an OBC reset had occurred on Tuesday, 13 May 2014, 16:27 UT and on 14 May 2014, 01:47 UT (9 h 20 min since first reset).

The reason for these resets and latchup are still unknown but currently all systems are working properly. Due to that we prefer to leave the satellite in safe mode during passes outside the range of our ground station in Vilnius.

Best Regards,
LituanicaSAT-1 team

434 MHz balloons have a role in STEM Education

Horizon Project - Gagarin - Isle of Wight

Project Horizon – Gagarin – Isle of Wight

The UK Department for Education (DfE) has selected the Horizon balloon project to feature in the department’s #yourlife campaign to promote Maths and Science.

Horizon Team Hard at Work

Horizon Team Hard at Work

Pupils at Queen Mary’s Grammar School, Walsall built the Gagarin payload which transmitted FSK RTTY telemetry data on 434.075 MHz. The students launched it on a high altitude weather balloon which reached an altitude of 35,118 metres before bursting. The Gagarin payload returned safely to Earth by parachute and the students were able to retrieve the stunning still images and video taken in near-space.

The telemetry transmitter could be received over most of the British Isles and radio amateurs were able to track the balloon’s progress from the transmitted GPS data. The Horizon team used a Yaesu FT-817 transceiver to receive the signal from the balloon and dl-fldigi software to decode it. Among those supporting the project were Yaesu and Essex-based Rapid Electronics.

Adam Coghlan, a mathematics teacher at the school, says:

There have been two teams worth of pupils involved in this project and UKHAS members have helped track every launch.

The pupils get so much out of it:
– many go on to start their own projects after a year in the Horizon Team
– most of the team members have reported extremely positive university interviews following their involvement with the project (some have had personal letters from lecturers and letters from universities wishing them luck, hoping that they’ll choose xxxxx when results day comes etc)
– team members who have visited us having left the school for university have got involved in projects at university and have been a lot more open to the opportunities at university beyond their academic studies

The project has a big impact on the pupils who take part and we’re so grateful to the UKHAS members who have supported us and who help with the tracking on launch days.

FUNcube-1 AO-73 satellite SSB signal test

This video shows Simon 2E0HTS carrying out a signal test on the FUNcube-1 AO-73 CubeSat, he gets a good signal back from the satellite.

During weekday daylight hours the satellite is in Educational Mode transmitting a strong telemetry signal with science data for schools to receive. On weekday evenings, when the satellite is in darkness, and throughout the weekend the FUNcube SSB/CW transponder is activated. SSB contacts can be made with as little as 5 watts.

To minimize Doppler shift the satellite uses what is known as an Inverting Transponder,  this means you transmit lower sideband (LSB) in the 435 MHz band and receives upper sideband (USB) in 145 MHz.

Watch Ham Radio – FUNcube AO 73 Signal check

FUNcube-1 frequencies
• 145.935 MHz BPSK Telemetry 30 or 300 mW
• Inverting SSB/CW transponder 300 mW PEP
– 435.150 — 435.130 MHz Uplink LSB
– 145.950 — 145.970 MHz Downlink USB
Educational Telemetry beacon is 300 mW during day and 30 mW at night.
The Transponder is only active during weekday night passes and at weekends.

David Bowman G0MRF giving one of his popular FUNcube satellite presentations

On Friday, July 4, the Whitton Amateur Radio Group (WARG) will be hosting a presentation by David Bowman G0MRF on the subject of the FUNcube satellite.

David is a member of the AMSAT-UK team behind the successful development and launch of the amateur radio FUNcube-1 CubeSat which transmits telemetry for Educational outreach (STEM) and carries a 435/145MHz SSB/CW transponder. The presentation will have a live reception of the satellite as it passes over Europe.

The meeting is open to all, the doors open at 7 pm and the talk commences at 8:15 pm. Whitton Community Centre has good car parking and disabled access as well as the use of the bar. A small charge of £1.50 per person will be asked to cover room hire.

The venue is the Whitton Community Centre, Percy Road, Whitton, Middx, TW2 6JL

Directions can be found on the Whitton Amateur Radio Group site http://www.warg.info/
