ARLA/CLUSTER: França, Lituânia, Malta, Eslovénia e Holanda querem retirar aos radioamadores a banda dos 23 cm (1240-1300 MHz) pelas interferências causadas ao sistema de GPS Galileu

Threat to Amateur Radio 23cm band

A joint paper to be submitted to the CEPT CPG meeting in Ankara by France,
Lithuania, Malta, Slovenia and The Netherlands 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.
