The 24th General Conference of IARU Region 1 was held in Landshut near München on September 17-21, 2017. In recognition of his outstanding and ongoing work with Satellite Coordination the IARU Region 1 Medal was awarded to Graham Shirville G3VZV.
As the global federation of national associations of radio amateurs in more than 150 countries, the International Amateur Radio Union (IARU) for many years has provided frequency coordination services for amateur satellites free of charge.
Often these satellites are constructed by students at universities and other institutions as a part of their educational experience. In general, they have been licensed to operate in the amateur-satellite service, which is defined by the Radio Regulations of the International Telecommunication Union (ITU) as having the “…purpose of self-training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized persons interested in radio technique solely with a personal aim and without pecuniary interest.”
Some administrations have issued experimental licenses for such satellites operating in amateur-satellite frequency bands. The IARU has coordinated these satellites as well, to reduce the possibility of harmful interference that might result from uncoordinated operation. Since 1 July 2014 it has not been possible to coordinate experimental satellites in the 144-146 MHz band because of the high probability of harmful interference in this heavily used band.
Educational satellite projects have grown in popularity as launch opportunities have increased. In 2012 the ITU World Radiocommunication Conference took note of the proliferation of what in Resolution 757 (WRC-12) it called “nanosatellites and picosatellites” and invited WRC-18 (now scheduled for 2019) to consider steps to facilitate their deployment and operation. Two Reports, ITU-R SA.2312 (09/2014) and ITU-R SA.2348 (05/2015), are instructive regarding the characteristics, definitions, spectrum requirements, and notification procedures of and for such satellites, which generally must use spectrum below 1 GHz for operational reasons.
At the following WRC in 2015, in place of Resolution 757 the Member States of the ITU adopted Resolution 659 (WRC-15) in which it was noted that the use of 144-146 MHz and 435-438 MHz by non-amateur satellites is not in accordance with the definition of the amateur-satellite service in the Radio Regulations. Resolution 659 cites the two reports mentioned above and makes it clear that the spectrum needs of what are now called “non-geostationary satellites with short duration missions” should be met either within the service in which the space station is operating or within the space operation service. Further, if new or upgraded allocations to the space operation service are required, studies should be limited to the frequency ranges 150.05-174 MHz and 400.15-420 MHz.
Accordingly, effective 1 August 2017 the IARU will be following revised guidelines for satellite frequency coordination.
The strong preference is for all satellites using spectrum allocated to the amateur and amateur-satellite services to operate under amateur licenses and within the definition of the amateur-satellite service and the service-specific Article 25 of the Radio Regulations. The IARU believes the definition is sufficiently broad to encompass nearly all educational satellite projects that include giving students hands-on experience with radiocommunication and are conducted under an amateur license.
The IARU will only coordinate a non-amateur satellite if an administration directs in writing that it be operated in an amateur-satellite band under an experimental or other non-amateur license.
Satellites with combined amateur and non-amateur missions will continue to be coordinated.

The document mentions the need for the expansion of the 20m band from 14000-14350 kHz to 14000-14400 kHz which was the spectrum originally allocated to amateurs at the 1927 Washington Conference. No expansion to the 14 MHz Amateur-Satellite allocation is planned.
The IARU seeks expansion to 250 kHz of the Amateur-Satellite Service allocations at both 18 and 24 MHz.
A harmonized allocation for the Amateur-Satellite Service is sought at 50-54 MHz, to bridge the gap between 28 MHz and 144 MHz but it should be noted the IARU plans for a harmonized 50 MHz band at WRC-18 are for the Amateur Service only not Amateur Satellites.
The document notes that because of the crowding of the existing band 435-438 MHz with uncrewed amateur satellites and crewed space stations, it is desirable to study expansion of the band. This is exactly what the IARU were saying over 8 years ago, as yet they do not appear to have actually studied band expansion. See the 2008 IARU Spectrum Requirements document.
Regarding the existing 1260-1270 MHz Amateur-Satellite Service allocation the IARU say they seek the deletion of the “Earth-to-space only” restriction. They note that WRC-2000 allocated the band 1240-1300 MHz to the radiodetermination-satellite service for space-to-space use. In addition, WRC-2000 allocated the band 1260-1300 MHz to the radiodetermination-satellite service for space-to-Earth use such as for the European Galileo positioning system. These actions do not change the Amateur and Amateur-Satellite Service allocations but present new sharing situations and potential operating restrictions.
Due to the high level of interference from license exempt devices substitute spectrum for the Amateur-Satellite Service 2400-2450 MHz allocation is sought.
It seems the IARU no longer any intends to seek a global Amateur-Satellite Service allocation at 3400-3410 MHz.
There are no plans to improve the status of Amateur-Satellite allocations at 5 or 10 GHz.

Some 70 delegates from over 20 Member Societies discussed a wide range of issues in the VHF/UHF/Microwave, HF and EMC Committees. Recommendations from the meeting will be considered by the Region 1 Executive Committee at its meeting in early May 2016. If approved by the EC, these recommendations will become interim Region 1 policy until the next General Conference in 2017, at which time all Societies present will have the opportunity to ratify the proposals.
Among the key items in the minutes are:
4.1. Report of satellite coordinator C5_04
Graham Shirville G3VZV presented the report of satellite coordinator. G3VZV emphasized that the frequency coordination between the three Regions has to be improved for avoiding interference incidents like PC-Sat and some of the XW2 satellites.
Due to current reports from MS about some observations of harmful interference, RSGB is asked to prepare a statement for publishing to inform MS and members how to take care.
C5 chairman is asked to bring up the issue on EC meeting, because further AC action is required.
5.2. Band Planning 5 GHz: C5_10
VIE16_C5_Rec_06: To correct the satellite segment the table in chapter 4.9 by deleting “5790”, inserting “5830” and adding the footnote: “Any wideband system shall protect narrowband applications”.
6.1. General matters: C5_26
VIE16_C5_Rec_11A: To discuss an even more extended [Grid Square] locator system that is used for ATV (including IARU ATV contest) and for other purposes by using the Wiki and prepares a document for GC 2017 if necessary. (Note this will clarify the definition of 10 digit [character] locators used for microwaves etc see example at http://no.nonsense.ee/qth/map.html )
7.2. APRS Harmonisation: C5_41
VIE16_C5_Rec_23: The C5 chairman to answer Regions 2 and 3 that:
• 144.390 MHz is not suitable for Region 1 and that Region-3 should consider 144.800
• To consider an additional 144 MHz frequency (that might be compatible) with Region 2 and 3
• To also consider 435 MHz usage and newer APRS technologies (for the 2017 GC)
The input papers are available as a matter of record:

VIE16_C5_41_1.pdf – 144 /435 MHz APRS Harmonisation
The paper covers global band planning considerations and among the recommendations says:
Emphasise that spaceborne APRS must be confined to globally coordinated amateur satellite sub bands. Therefore items that are ambiguous and generate confusion in national band plans such as ‘Space communications’ and ‘New Oscar Sub band’ should be removed as soon as possible in all Regions in accordance with IARU-AC and Satellite Coordination guidance
It is believed that ‘New Oscar Sub band’ refers to the USA’s ARRL 144 MHz band plan and ‘Space communications’ to the Australian WIA 144 MHz band plan. These band plans, as well as those for some other countries, show 144.300 – 144.500 MHz as being for Amateur Satellite use.

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.
