UBSEDS18 Solar Powered Balloon
On Sunday Bristol SEDS students plan to launch a 434 MHz and APRS solar powered balloon that may travel around the world.
Another pico launch from Bristol this Sunday, December 11 between 0500 and 0530 GMT. This launch is using a 1.9m envelope and longer payload train, and so we have a NOTAM in place. The flight is predicted to head south-east towards France.
The payload will be transmitting Contestia 16/1000 on 434.610 MHz USB. Each transmission of Contestia 16/1000 will be preceded by 10 seconds of pips and RSID.
The Contestia transmission rate will be once every 30 seconds during launch and when power is available during the day. Otherwise the transmission rate will be once every 2 minutes. Hopefully the tracker will operate from dawn to dusk, and maybe also during the night.
The tracker will transmit APRS outside countries where the amateur license is not permitted airborne (like the UK). Additionally it will test APRS on 145.825 MHz, with an output power of +26 dBm (400 mW).
More details will appear on the website http://www.bristol-seds.co.uk/flights.html

XW-2A satellite was launched September 19, 2015
CAMSAT is working closely with a Beijing Government aerospace contractor to build two satellites with amateur radio linear transponder payloads.
Both will carry a 435/145 (U/V) 20 dBm (100 milliwatt) SSB/CW linear transponder, a 2m CW 17 dBm (50 mW) telemetry beacon and an AX.25 4.8 kbps GMSK 20 dBm (100 mW) telemetry downlink.
Each set of amateur radio equipment will have the same technical characteristics, but will have different frequencies for the 70cm band uplinks and 2m band downlinks.
The two micro-satellites will also carry optical remote sensing missions. Planned to be 494x499x630 mm dimension regular square shape and approximately 50 kg mass with three-axis stabilization system.
Expecting a launch from Taiyuan on March 31, 2017 into a 524 km SSO with an inclination of 42 degrees.

Sandringham students operating the GB16YOTA amateur radio station, December 1, 2016
Students at Sandringham School plan to launch a High Altitude Balloon with a Raspberry Pi payload into near-space and transmit back pictures.
The downlink from the balloon is expected to be in 434 MHz and at the maximum 30 km altitude the radio signal should have a range of up to 800 km enabling reception by radio amateurs across the British Isles and into Europe.
The launch is planned for Science Week, March 13-17, and the students will use the download data they collect from near space for analysis and use in lessons.
Earlier this year Sandringham students used amateur radio to talk to UK astronaut Tim Peake GB1SS on the International Space Station, see https://amsat-uk.org/2016/01/08/bbc-tv-sandringham-school-amateur-radio-iss-contact/

The Tancredo-1 satellite, a small TubeSat built by middle school students in Brazil, is scheduled to be sent to the International Space Station on December 9, 2016. The satellite will be sent to the ISS inside the TuPOD TubeSat deployer onboard JAXA’s KOUNOTORI6 cargo ship (HTV-6 mission). The TuPOD is expected to be ejected into space by the J-SSOD satellite deployer on December 19th and on December 21st, Tancredo-1 is expected to be finally ejected from the TuPOD into space. Once in space, Tancredo-1 will start transmitting telemetry data.
Tancredo-1 is the first satellite of the Ubatubasat project, a STEM project idealized by Prof. Cândido Oswaldo de Moura at Escola Municipal Tancredo Neves public school in Ubatuba, state of Sao Paulo, Brazil. The project is supported by the Brazilian Institute for Space Research (INPE) and the Brazilian Space Agency (AEB). Tancredo-1 will initially have the same orbit as the ISS, but it will slowly drift with time and will eventually reenter in the atmosphere and burn.
The Ubatubasat project team and AMSAT-BR would like to kindly request radio amateurs around the planet to monitor and report any signals heard from Tancredo-1. Please send any reports (audio, AX.25 KISS files, etc) to firstname.lastname@example.org
Tancredo-1 will transmit on 437.200 MHz using 1200 bps AFSK AX.25.

ISS SSTV image 2 received by Mike Rupprecht DK3WN April 12, 2016 at 1556 UT
Slow-scan television (SSTV) transmissions are planned from the International Space Station (ISS) on December 8-9, 2016.
The SSTV images will be transmitted as part of the MAI-75 Experiment on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module.
The MAI-75 activities have been scheduled for the Russian crew on Dec 8 from 12:35 to 18:00 GMT and Dec 9 from 12:40 to 17:40 GMT.
Note the ISS transmissions on 145.800 MHz FM use the 5 kHz deviation standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try the wider filter.
The ISS Fan Club website will show you when the space station is in range http://www.issfanclub.com/

Cornwall Live reports that radio amateur David Honess M6DNT has been awarded a prestigious space achievement honour for his Astro Pi work with the Tim Peake GB1SS Principia mission.
David Honess M6DNT was presented with a Sir Arthur Clarke Award, on behalf of the Arthur C. Clarke Foundation and the British Interplanetary Society, for Space Achievement – Industry/Project Individual.
This came after Mr Honess and his Astro Pi project which installed two Raspberry Pi’s (Izzy and Ed) on to the International Space Station as the platform for students to run their own code in space and speak with Major Tim Peake GB1SS.
Mr Honess has been “the driving force” behind getting two UK designed and manufactured Astro Pi computers onto the International Space Station to provide a unique facility to inspire children and adults to learn to code.
