Threat to Amateur Radio 23cm band

Galileo LogoA joint paper by France, Lithuania, Malta, Slovenia and The Netherlands for the CEPT CPG meeting in Ankara, August 26-30, attacks the continued use by Radio Amateurs of our 1240-1300 MHz band.

This is the final CEPT CPG meeting in preparation for the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.

Paper AI10 – Proposal on AS-RNSS says:

Galileo is close to full operational capability and its E6 signals in the band 1260-1300 MHz will support new services such as the free-to-use Galileo High Accuracy Service, and also robust authentication, expected to be used by a variety of applications including autonomous vehicles and the Internet of Things (IoT).

Several cases of interference to Galileo E6 receivers from amateur service emissions have occurred in the recent past, sometimes at significant distance, and have taken several hours or even days to be eliminated. There is therefore a serious concern that as Galileo E6 receivers are deployed and used more widely, cases of interference from amateur stations will rapidly grow in number.

A WRC-23 agenda item is necessary to address this issue because:

1. Unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers. This is demonstrated by experience.

2. The number of Galileo receivers in 1260-1300 MHz will increase dramatically, and interference cases will multiply if not addressed timely.

3. Galileo and other RNSS systems will deploy at global scale, and interference scenario between amateur emissions and RNSS receivers include cross-border cases. The issue is therefore of international nature and is to be addressed in the ITU framework.

4. Galileo is a major European asset, and a decision at WRC-23 is essential to be compatible with the roadmap of deployment of Galileo receivers in this band.

SSA defends 23cm band against Galileo threat

Galileo LogoSweden’s national amateur radio society, the SSA, has sent a supplementary letter to the communications regulator PTS ahead of the next meeting of the CEPT ECC Conference Preparatory Group CPG-19.

The SSA report:

At a previous CEPT meeting (PTA), France has proposed an agenda item to WRC-23 that the coexistence between satellite navigation (eg Galileo) and amateur radio in the band 1240-1300 MHz should be investigated. The proposal was voted down at the preparatory PTA meeting, but France has now sent letters to the various telecommunications authorities with a request that they now support this proposal at the forthcoming CPG19-9. SSA opposes this.

SSA has therefore sent a supplementary letter to PTS about our 23 cm amateur band. Our section leader for IARU and VUSHF Mats SM6EAN explains the background and our opinion on our section pages. Here you can also read the new letter to PTS.

144 and 1240 MHz bands – WRC-23 Agenda Items – Update

IARU was represented at the meeting of CEPT Project Team A (responsible for some aspects of the CEPT position for WRC-19), held in Prague from June 17-21.

The IARU Region 1 website reports:

Of particular interest were discussions on two proposed Agenda items for WRC-23, concerning the sharing of the 1240-1300 MHz band with the Galileo navigation system and the proposal from France to study a range of frequencies, including the 144 MHz amateur band, for future aeronautical applications.

The output from PTA does not carry forward the Galileo proposal, but it is likely that further discussions will take place prior to the Conference Preparatory Group meeting in August. Meantime work on this issue will also continue in other specialist CEPT forums. IARU will continue to support this approach and it believes this will be the most efficient method for developing the sharing guidance required to protect Galileo operations in a timely manner.

Regarding new aeronautical frequencies (including 144-146 MHz), the proposal was not strongly opposed by administrations and has been carried forward to the higher level CEPT Conference Preparatory Group (CPG) meeting in August for final adoption.

IARU views with grave concern any proposal to include the 144 MHz band in the proposed aeronautical agenda item and will be making every effort to fully protect amateur radio interests and seek the support of regulators in this regard.

The band 144-146 MHz is allocated globally to the amateur and amateur satellite services on a primary basis. It is the only globally harmonised VHF band for the amateur and amateur satellite service. As such it is an important and widely used part of the amateur spectrum with a vast installed base of both terrestrial/maritime amateur users and systems and operational satellite stations including the International Space Station (ISS).

This heavily used band supports a large number of repeater stations, segments for weak-signal long distance terrestrial and EME (Earth-Moon-Earth) communications, satellite and ISS usage, data services, as well as conventional terrestrial and tropospheric communications. The Primary status of the band has also enabled a number of amateur aeronautical uses including on manned flights and high-altitude balloons. Supporting all of this is a wide variety of commercial and experimental equipment, ranging from ultra-low noise preamplifiers for sensitive receivers, software defined radios and transmitting systems that can deliver high EIRP levels when needed to overcome high loss propagation paths.

Given the propagation to/from an aircraft at altitude, it is entirely possible that harmful interference to sensitive amateur and amateur satellite receivers will be caused over a 1,000 km radius of a single aircraft.

IARU will shortly be providing a brief to Member Societies and other interested parties, asking them to discuss the French proposal with their administrations well in advance of the August CEPT-CPG meeting.

It is possible that France will seek to introduce into other Regional Telecommunications Organisations (RTO) the same proposal to study the 144-146 MHz band for aeronautical use. IARU will provide a brief shortly to enable representations to be made to administrations in countries under those RTOs for protection of this amateur spectrum allocation.

1240-1300 MHz band discussed by CEPT WGFM and CPG/PTA

WRC-2000 saw the Galileo Global Navigation Satellite System (GNSS) get an allocation at 1260-1300 MHz. This was the same ITU conference that saw 432-438 MHz being allocated for satellites that carry Synthetic-Aperture Radar (SAR) systems.

In January 2006 Peter Blair G3LTF published a paper Potential Interference To Galileo From 23cm Band Operations. This described the proposed Galileo system design and its applications with particular reference to the E6 (1260-1300 MHz) band. It described the operation of typical Galileo receivers and their ability to deal with interference and gave practical illustrations of these effects.

The 30-satellite Galileo system (24 operational and 6 active spares) is expected to be completed by 2020.

A paper at the CEPT WGFM meeting #93 held in Rome, February 4-8, 2019, titled Coexistence between AS [Amateur Services] and RNSS in the Frequency Range 1260-1300 MHz said:

At the most recent meeting of CPG/PTA #5 in September 2018 the European Commission provided a proposal for Agenda Item 10 of WRC-19 on the amateur service allocation in L band. The EC contribution (CPG/PTA(18)080) proposed to consider an extension of the spectrum allocation to the amateur service on a secondary basis in the range 1300 – 1350 MHz. Germany announced at that meeting that a measurement campaign was already planned to investigate further the coexistence of applications in the amateur service and the radionavigation-satellite service [RNSS] particularly in the frequency range 1260 – 1300 MHz.

Since then these measurements were carried out at the premises of the “Universität der Bundeswehr München” (University of Federal Armed Forces Munich) mid December 2018 and a report on the issue is in preparation. At CPG/PTA #5 the meeting agreed to wait for the results of the measurement before taking any further action. Currently the measurement data is being processed and the results will be reported to CPG/PTA #6 in April 2019. Germany would offer to present this report also to WG FM.

Depending on the results the issue could become an enforcement issue for CEPT and, hence, may become a topic for further consideration in WG FM and WG SE.

https://cept.org/Documents/wg-fm/49268/fm-19-069_information-on-measurement-campaign-on-as-gnss-in-1260-1300-mhz-germany

The CPG/PTA meeting #6 held in Bucharest April 1-5, 2019, saw this proposal:

PTA is asked to consider the results of these tests to determine if appropriate actions are required.

A possible action could be to propose a new Agenda Item for WRC-23 to address the issue. The subject could be: to consider the possible additional spectrum allocation to the amateur service on a secondary basis above 1300 MHz (or in another frequency band to be determined), with a view to progressively migrate the radio amateurs services from the band 1240-1300 MHz to the new band. To study an ITU recommendation for the coexistence of services in the band 1240-1300 MHz in the short/medium term.

The Belgium regulator BIPT has proposed cutting to just 20 watts the permitted power level for the Amateur and Amateur-Satellite allocations in 1260-1300 MHz which is to be used by the Galileo GNSS / GPS constellation.

A Google translation of the UBA post reads:

On December 18, the BIPT website provides BIPT consultation on the Frequencies, Power and Transmission modes that may be used by radio amateurs.

This consultation was already announced at the BIPT meeting with the recognized associations of September 28 and should provide a framework for the introduction of the CEPT Novice license in Belgium.

The most important part is the Appendix 1 which establishes the Frequency bands and technical characteristics allowed for the different categories of radio amateur licenses.

For holders of a HAREC license (class A operating certificate), there are only changes to the transmission power (usually in our favor):

• On most bands between 1.81 MHz and 440 MHz, the permitted power is 1500 W. Exceptions are 1.85-2.00 MHz (10 W), 5.3515-5.3665 MHz (15 W EIRP), 50-52 MHz (200 W), 69.95 MHz (10 W). EIRP), 70.1125-70.4125 MHz (50W) and 433.05-434.79 MHz (200W EIRP for (D-) ATV, 200W transmit power for other modes). On the bands above 1 GHz the permissible power is increased to 200 W, with the exception of 1260-1300 MHz (20 W). The special license for higher capital expires, but to perform exceptional experiments one can still submit a motivated request to temporarily use a larger capital. It is allowed to own devices that are capable of supplying a power up to twice the permitted maximum power.

The holders of the newly introduced CEPT Novice license (class B operating license) have access to almost all bands between 1.81 MHz and 440 MHz (except 5.3515-5.3665 MHz, 69.95 MHz and 70.1125-70.4125 MHz). The permitted transmission power is 100W at HF ​​and 6 meters and 50 W at 2 m and 70 cm. All classes of broadcast (modes) are allowed with the exception of D-ATV.
For the holders of a basic license (class C operating license) the changes are greater:

• The permissible transmission power is limited to 10 W, but the use of devices up to 100 W transmission power remains permitted (provided that the power is limited to 10 W). The use of external power amplifiers is not permitted.
• The use of the 17 m band (now 18.080-18.168 MHz), 12 m band (now 24.900-24.990 MHz) and 6 m band (now 50.125-52.000 MHz) is no longer allowed.
• The 20 m band is expanded (14,000-14,150 and 14,250-14,350 MHz), this is 65 kHz extra (14,080-140150 MHz).
• The 15 m band is expanded (21,000-21,150 and 21,320-21,450 MHz), this is 90 kHz extra (21,000-21,040 and 21,100-21,150 MHz).
• The 10 m band is expanded (28,000-29,700 MHz), this is 40 kHz extra (28,000-28,040 MHz).
• The permitted classes of broadcast (modes) do not change, everything modes except (D-) ATV remain allowed.

Galileo GNSS/GPS – FCC to vote on use of signals in USA

FCC SealThe Federal Communications Commission (FCC) has said it will vote in November on whether to allow U.S. GPS receivers to access the Galileo global navigation satellite system (GNSS).

From an Amateur Radio perspective the key part is that the FCC will only be voting to waive its licensing requirements for non-federal operations with Galileo channels E1 and E5, subject to certain technical constraints.

This means they will not be voting on the E6 channel 1260-1300 MHz, these frequencies are also Amateur and Amateur-Satellite Service allocations. This suggests for 1260-1300 MHz the situation in the USA will be unchanged, the unlicensed use of the Galileo signal on channel E6 will not be permitted for non-Federal operations in the USA.

Read the Reuters story which also says Ajit Pai is proposing the first comprehensive review of the FCC’s orbital debris rules since their adoption in 2004
