IARU issue Amateur-Satellite Service spectrum requirements

IARU_LogoThe IARU has released a revised edition of Spectrum Requirements for the Amateur and Amateur-Satellite Services.

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.

IARU-R1: Global APRS Harmonisation and Satellite Coordination

IARU_Region_1_logoThe IARU Region 1 Interim Meeting was held April 15-17, 2016 in Vienna. Minutes for the C5 VHF/UHF/Microwave committee are now available.

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)

IARU Paper: APRS Harmonization and removal of OSCAR sub-band

IARU_Region_1_logoIARU Region 1 has released the papers for the Interim Meeting to be held in Vienna April 15-17, 2016.

Among the papers for the C5 VHF/UHF/Microwave Committee is one on harmonizing APRS.

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.

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.

IARU Region 3 Conference

IARU-R3 LogoThe ARRL reports on the 16th International Amateur Radio Union (IARU) Region 3 triennial conference held in Bali, Indonesia, October 12-16.

Working Group 2 (WG2) dealt with such operational and technical matters as emergency communication, digital modes, a common APRS frequency, and Region 3 band plans. Titon Dutono, YB3PET, chaired WG2, and ARRL CEO David Sumner, K1ZZ, served as its secretary. In all, working group members discussed 37 papers and submitted recommendations to the conference for adoption.

Among recommendations adopted was one to ask the IARU Administrative Council to make available information on the use of the Amateur Satellite Service for member societies, satellite groups, Amateur Satellite operators, and concerned radio amateurs. This information would include, but not be limited to, criteria for a satellite to be in the Amateur Satellite Service and the procedure for IARU satellite frequency coordination.

The conference also adopted adjustments to the Region 3 band plans. Region 3 directors will consider making the format similar to that used in Regions 1 and 2.

The Chinese Radio Sports Association / Chinese Radio Amateur Club submitted a paper titled Amateur Satellite Guide which said “Amateur satellite projects may rely on a wide range of cooperation between radio amateurs and other parties, as the consequence, the nature of the mission can be complicated. Without a set of definite criterion, the service classification of a mission may not be crystal clear to both satellite operators and other radio amateurs, especially when the radio payload supplies amateur service but also covers certain kind of other tasks.”

The CRSA/CRAC proposed “that the IARU AC shall consider to make available some information on use of the amateur satellite service for member societies, satellite groups, amateur satellite operators as well as concerned radio amateurs.”

IARU Region 3 Act on Band Plan Satellite Allocations

Sanur Paradise Plaza Hotel

Sanur Paradise Plaza Hotel

The IARU Region 3 (Asia/Pacific) Directors have submitted a band plan paper concerning amateur satellite allocations for consideration at the IARU Region 3 Conference which takes place October 12-16 in Bali, Indonesia.

IARU-R3 LogoThis is the 16th Conference and it will be hosted by the Amateur Radio Organisation of Indonesia (ORARI). 60 Premier and 12 Suite hotel rooms have been booked at the Sanur Paradise Plaza Hotel which is described as being situated in Sanur, the secretly sophisticated side of Bali.

ORARI plans to run a special event station YB16IARU from October 11-16 from the conference and the delegates will be taken on a tour of Bali.

The President of ORARI, Sutiyoso YB0ST, says: “It’s an exciting time for us as we continue to grow and thrive, remaining always adaptable, motivated and responsive. The world of amateur radio is an exciting area in which to work and play, and we’ll continue to meet and bring inspired people together in forums like this, to ensure IARU Region 3 remains at the cutting edge.”

The IARU Region 3 Directors have acknowledged the existing 2m band plan does not adequately define how stations in the Amateur Satellite Service may use the band. However, the changes they are proposing would appear to prohibit the use of the Amateur Satellite Service channel 144.490 MHz as an uplink for crewed space missions. Use of this channel was agreed by IARU Region 3 some 20 years ago but the new paper says:

“Note 2: The other portion of the band 144.035-145.8 MHz is exclusively identified for the amateur service.”

At the same time IARU Region 3 had agreed the crewed space mission downlink channel would be 145.800 MHz using 5 kHz deviation FM with a Doppler shift of +/- 3.5 kHz. The paper does not record this.
