WRC-15: Amateur Bands Unsuitable for Non-Amateur Satellites

Logo WRC RA 2015The World Radiocommunication Conference (WRC) held in Geneva during November 2015 has recommended an agenda for the next WRC, to be held in 2019, to the Council of the International Telecommunication Union (ITU). One of the agenda items is of particular interest to the small-satellite community.

Agenda item 1.7 for WRC-19 reads: “to study the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution COM6/19 (WRC-15).”

Resolution COM6/19, which eventually will be given a new number, specifies the frequency ranges that may be considered for possible new allocations. They are 150.05-174 MHz and 400.15-420 MHz.

One of the factors that the conference considered in deciding on these particular frequency ranges was “that some non-amateur satellites have used frequencies for telemetry, tracking and command in the frequency bands 144-146 MHz and 435-438 MHz which are allocated to the amateur-satellite service, and that such use is not in accordance with Nos. 1.56 and 1.57.” Those two provisions of the ITU Radio Regulations define the amateur and amateur-satellite services respectively.

The International Amateur Radio Union welcomed the exclusion from consideration of all existing frequency allocations to the amateur and amateur-satellite services. IARU President Tim Ellam, VE6SH, observed: “This is an excellent result for the amateur services and clearly shows that non-amateur satellite constructors need to consider spectrum other than the very limited and congested segments that are available for amateur satellites at 144 MHz and 435 MHz.”

In his report for Day 16 of the conference Colin Thomas G3PSM says:

Discussions took place on suggested frequency bands for possible new or an upgrade of existing allocations to the space operations service within the frequency ranges 150.05-174 MHz, 400.15-420 MHz [and 420-450 MHz] for short duration satellites.

This potential future agenda item is an attempt to overcome the problem of non-amateur nano- and pico-satellites using the amateur service bands. No decision was reached and the document has been passed to plenary for decision.

Successful SSTV and Digitalker transmissions from SPROUT

SPROUT SSTV received by Paulo PV8DX Nov 22, 2015

SPROUT SSTV received by Paulo PV8DX

On November 22, 2015 SSTV and Digitalker transmissions were made from the SPROUT amateur radio satellite on 437.600 MHz FM (+/- 9 kHz Doppler shift). These transmissions are planned to take place every Sunday (Japanese Standard Time).

Many FM radios can be switched been wide and narrow deviation FM filters. For best results you should select the wider filter designed for 5 kHz deviation FM.

SPROUT (Space Research On Unique Technology) was built by students from Nihon University. It is a 20 x 20 x 22 cm nano-satellite with a mass of 7.1 kg in a 654 km, 97.9 degree inclination Sun Synchronous Orbit (SSO).

Paulo PV8DX in Brazil reports receiving both the SSTV image and the Digitalker transmission a recording of which can be heard here:

Second Birthday of FUNcube-1

FUNcube-1 (AO-73) was launched into space two years ago on November 21, 2013.

We are delighted to be able to report that more than 900 stations, including many schools around the world, have received the telemetry from the spacecraft since launch. Our Data Warehouse is storing more than 750 MB of data from almost 1 million data packets. We are very grateful to everyone who has been contributing to the success of this mission. Please continue to keep the data flowing as it will provide a valuable resource for students in the future.

The stats continue – speeding along at around 17,500 mph, FUNcube-1, which had a launch mass of just 982 grams, has completed more than 10,500 orbits of the earth. This means a total distance travelled of more than 260 million miles.

All telemetry sensors continue to provide valid data, real time, whole orbit and high resolution channels alike. The flight code is really robust and we have only had three unexpected “events” since launch. Two of these we believe to have been caused by noise of the command receiver being incorrectly interpreted as a command and only one appears to have been caused by a RAM error. The battery and solar panels also continue to work perfectly and provide a very positive power budget.

We have sent out many Fitter messages for school and other similar events. On November 17, 2015 there was a demonstration at Thorne Green Top School in Yorkshire. Here is a report from Dave Ryan EI4HT/M0GIW:

FUNcube-1 Educational Outreach - Thorne Green Top School in Yorkshire

FUNcube-1 Educational Outreach – Thorne Green Top School in Yorkshire

Good Morning All  

Firstly -thanks to all for your help, we had a great morning at Green Top and the highlight was FUNcube.

I started with a slide show talking about communications from cave paintings all the way up to smartphones, we looked at space communications and travel from Sputnik to Astra and Apollo to the Millennium Falcon! We spoke about satellites and how they are used every day and how we all got to watch “I’m A Celebrity” via Satellite last night from Australia.

I brought in lots of props too, some old Motorola MX330 radios, some PMR 446, and a marine band radio .I also had a small model of a CubeSat that I knocked up over the weekend, I also passed around some NOAA images from last week’s Abigail storm and I had a few QSL cards from ISS and MIR from years ago when I lived in Ireland.  

The FUNcube pass was great, really strong signals, I had my turnstile and FCD set up and had audio through speakers and used the class projector to show Satpc32 and the Dashboard.  

There was a great buzz of excitement when we got the first packet and even more when the Fitter messages came through. The kids were fascinated to see the signal arrive just as the software predicted and then hear the telemetry and the decode.  

After the pass we were able to look at the Warehouse online and print off the QSL card and certificate.

 I didn’t get a chance to take many pics but Mrs Overson will update the School Blog and she took lots of pics.

Once again thanks to all at FUNcube, looking forward to Tim Peake on the ISS in the New Year and planning another visit to the School then.

Regards

Dave EI4HT / M0GIW

PS: I was back dropping my own kids off this morning and Mrs Overson told me they have printed a QSL card and Certificate for each of the students and they have used them for their class journals.

As well providing a great educational resource, FUNcube-1 operates at night and generally at weekends with the linear transponder active for radio amateurs to use for communications. The transponder continues to provide an excellent service. As users will be aware, the transponder uplink frequencies vary with receiver temperature. The RX temp telemetry channel is the best one to use for tracking this effect. This does make it quite difficult to use full computer control for transponder operations and we have already developed new oscillator circuits to improve this performance for future missions.

For the telemetry uplinked to the Data Warehouse, it is possible to download special Certificate or QSL Card here http://amsatuk.me.uk/on/funcube_qsl.php and, for transponder users, the “73 on 73 award” continues at https://amsat-uk.org/funcube/73-on-73-award/

The Nayif-1 CubeSat mission, which includes a full FUNcube payload, is expected to be launched into a similar orbit in the first half of next year and will provide an additional level of service to the community.

Meanwhile we hope everyone will continue to have fun with FUNcube-1!
