AMSAT-UK and AMSAT-NL are delighted to be able to announce that they have been advised that the launch date for FUNcube-1 is now expected to be late November 2013. The date is still subject to final approval by the authorities.

The FUNcube project started back in 2009 so it is a great relief that we now have a confirmed date for lift off.

FUNcube-1 will lift off from the Yasny launch base located in the Orenburg Region, Russia on a Dnepr Launch Vehicle that will insert multiple satellites into a 600 km, 97.8º inclination sun-synchronous orbit.

FUNcube-1 is a 1U CubeSat that will provide a signal directly from a satellite in space to the classroom, and can easily be received by schools and colleges. The target audience is students at both primary and secondary levels. The information will be displayed in an attractive format and provide stimulation and encouragement for students to become interested in all STEM (Science Technology Engineering & Maths) subjects in an unique way. In addition the spacecraft is also carrying a 435/145 MHz transponder for radio amateurs to use for communication using SSB or CW.

The spacecraft itself has now been completed and the last external panel was finally screwed and glued in place on Friday, August 30 at the facilities of ISIS BV in Delft. FUNcube-1 will be subjected to some final testing and battery charging on Tuesday when it will also be set into its pre-launch configuration. It will then be placed into its ISIPOD on Wednesday ready for transport to the launch site.

Communication subsystem:
• 300 mW Inverting linear transponder for SSB and CW
– Uplink      435.150 – 435.130 MHz
– Downlink  145.950 – 145.970 MHz
• 300 mW BPSK Telemetry  145.935 MHz (30 mW when transponder active)

More information about how to receive the signals from FUNcube-1 will be made available over the forthcoming weeks at the www.funcube.org.uk website.

CEPT considers use of 5830-5850 MHz satellite band

CEPT LogoThe CEPT SE24 Short Range Devices meeting M72 took place in Vienna on August 26-27, 2013.

The meeting discussed the use of the frequency bands 5350-5470 MHz and 5725-5925 MHz (‘WAS/RLAN extension bands’) for wireless access systems including radio local area networks (WAS/RLANs).

Any use of Amateur Satellite Service downlink band of 5830-5850 MHz for this purpose would inevitably raise the noise floor making the weak satellite signals even harder to receive.

AX.25 packet radio is currently the most popular data protocol for use in CubeSats.

Radio amateur Alejandro Santos LU4EXT is developing extmodem an open source APRS compatible AX.25 packet radio modem.

It is currently capable of both sending and receive packets at 1200 bps AFSK. The main feature of the software is that it is currently running three different demodulators in parallel, increasing the quality of reception. The first modem is Thomas Sailer HB9JNX / AE4WA‘s multimon, the other two are described by Sivan Toledo 4X6IZ in an article in the July/August 2012 issue of QEX.

Giant leap for radio ham’s Pi-powered teddy bear

2013-08-26--14-45-58-PIE-51FBBC News reports on radio amateur Dave Akerman M6RPI‘s successful 434 MHz balloon flight on Monday, August 26, 2013.

The balloon carried transmitters on 434.200 MHz and 434.250 MHz and transmitted images using the amateur radio Slow Scan Digital Video (SSDV) standard, they are available here.

The BBC say:

A soft toy controlled by a Raspberry Pi computer has re-created Felix Baumgartner’s record-breaking skydive.Mr Baumgartner made the highest ever freefall in October 2012 when he jumped from a balloon about 39km up.

A bear called Babbage has now leapt from a similar height after ascending beneath a hydrogen-filled balloon.

The Raspberry Pi low-cost micro-computer inside Babbage transmitted his position and shot stills and video throughout the flight and descent.

UK radio ham’s Lunar CubeSat to go ahead

Pocket Spacecraft

Pocket Spacecraft

Michael Johnson M0MJJ gave a presentation on his Pocket Spacecraft: Mission to the Moon project to the AMSAT-UK International Space Colloquium held in July at Guildford.

He aimed to raise funding for the project by using the Kickstarter crowd-funding website.

The 60 fund raising period ended on August 26, 2013 and it fell short of target raising pledges for £69,079 ($107,735) out of the £290,000 ($452,284) goal. However, it appears that thanks to donations from other sources, the Pocket Spacecraft: Mission to the Moon is still going ahead.

Update #6 on the Kickstarter page says:

“More than 350 private individuals, universities and companies have backed the project via Kickstarter so far, but what we weren’t expecting are the amazing direct offers of financial support and support in kind that are too big or unable to be pledged via Kickstarter. Thanks to this support from private individuals, companies, government bodies, non-profits and others, we’re excited to be able to confirm that Pocket Spacecraft: Mission to the Moon will go ahead!”

The plan is that a 3U CubeSat will carry Pocket Spacecraft known as ‘Scouts’ to the Moon. A ‘Scout’ is a disk with flexible electronics, smaller than a CD, containing a transceiver, antenna and solar cells. The CubeSat should first release a batch of the wafer thin Scout satellites into Earth orbit and then deploy another batch of the Scout satellites into Lunar orbit.

It is understood the mission plans to use the 435 MHz and 2400 MHz bands.

The Kickstarter page says “If you are, or would like to be, a radio amateur, we’ll show you how to communicate directly with your spacecraft in space when it is nearby using inexpensive UHF and S-band equipment. Communication at (cis-)lunar distances is more expensive (typically requiring 5-24m+ steerable dishes), but available to some clubs and enthusiasts.”

Pocket Spacecraft is believed to be the first UK satellite project to have used Kickstarter. Several USA satellite projects have already successfully raised money on Kickstarter:

Radio ham Zac Manchester KD2BHC used Kickstarter to raise $74,586 in donations to fund the development and deployment of 200 amateur radio KickSat sprite satellites expected to take place later this year.

Radio amateurs Jeroen Cappaert KK6BLQ, Joel Spark KK6ANB and Jonathan Oxer VK3FADO are on the team of the ham radio satellite project ArduSat. They managed to raise donations of $106,330 in just 30 days.

SkyCube which will transmit on 915 MHz in the 902-928 MHz amateur radio band raised $116,890.

Kickstarter is not just about raising large sums of money, for example Sandy Antunes used Kickstarter to raise $2,780 to buy a ham radio transceiver and antennas to create an amateur radio satellite ground station Calliope.
