Funcube-1
• FUNcube-1 (AO73) is a complete educational single CubeSat project
with the goal of enthusing and educating young people about radio,
space, physics and electronics.
• The Funcube website is http://funcube.org.uk
• It has a materials science experiment with temperature sensors
• Temperature, voltage and current information is broadcast on the
telemetry frequency and can be displayed on the Funcube dashboard.
• Details of current operations and the telemetry available from
FUNcube-1 can be seen at http://warehouse.funcube.org.uk/
Cubesats
• 10cm x 10cm x 10cm (1U), or ~ x 20cm (2U), or ~ x 30cm (3U)
• Often launched alongside another larger satellite payload, or from ISS
• Kits available and launch cost of ~$80K brings within scope of
educational establishments etc.

Funcube-1 Educational operation
• Launched from Russia on a DNEPR rocket on 21st Nov 2013
• A complete educational single CubeSat project with the goal of
enthusing and educating young people about radio, space, physics
and electronics.
• Has on board temperature, lux, voltage and current sensors and
continuously reports the satellite status and conditions.
• A free dashboard program is available to display current data.
• Uses permanent magnets and the earths magnetic field for stability.
Capturing, uploading and viewing the data
• TLM down link freq 145.935 MHz BPSK
• SSB receiver (or Funcube dongle)
• PC with Funcube dashboard
• http://warehouse.funcube.org.uk/

• www.heavens-above.com – there is also a Heavens-Above app.
Funcube-1 Amateur Operation
• Transponder:
• Uplink 435.150 - 435.130 MHz LSB (Inverting)
• Downlink 145.950 - 145.970 MHz USB
• Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna. More
power is not needed to use the transponder!
• Times and modes
• Currently operating full power TLM beacon (300 mW) when Sat is in sunlight,
and Transponder, plus low power (30mW) TLM beacon when in eclipse.
• Also appears to be Transponder, plus low power TLM at weekends and bank
holidays – news on the Funcube website
• NORAD ID: 39444
Funcube-2 = Part of UKube-1
• UKube-1 (3U) is a number of experiments, one of which is Funcube-2.
• Successfully launched on a Soyuz rocket from Baikonur on July 8th
2014.
• Currently being commissioned, Funcube-2 data is sporadically tested.
• https://youtu.be/CDRz7r5Redw
• TLM down link frequency 145.915 MHz BPSK
• Amateur radio transponder has been tested and promises to be good.
Funcubes 3, (4) and “x”
• FUNcube-3 (EO79)
• Launched on a DNEPR on 19th June 2014 and commissioning is presently
underway.
• FUNcube (4) on Nayif-1
• Launch scheduled towards the end of 2015.
• FUNcube “x” – a payload on the ESEO mission.
• Launch tbc.
SO-50
