GNSS Re-transmitters – CEPT Activities

Existing frameworks and CEPT ECC Deliverables
regarding Work on GNSS- Re-transmitters
ECC Recommendation (10)02: a framework for the authorisation regime of Global
Navigation Satellite System (GNSS) repeaters
GNSS systems currently operate in the bands 1164-1215 MHz, 1215-1300 MHz
and 1559-1610 MHz;
technical compatibility of GNSS repeaters is provided in ECC Report 129 and the
regulatory considerations in companion ECC Report 145;
only be authorised on a site specific basis, mobile use should not be authorised;
that the use of radio frequencies by GNSS repeaters should be restricted to
professional applications for government associated agencies, and related
operators of indoor facilities where emergency services need to continue tracking
GNSS where it is otherwise unavailable;
Harmonised European Standard ETSI EN 302 645
Pseudolites (PL)
ECC Recommendation (11)08: Framework for authorisation regime of indoor global navigation satellite
system (GNSS) pseudolites in the band 1559-1610 MHz
ECC Report 168 Regulatory framework for Indoor GNSS pseudolites
indoor GNSS PL should be authorised in the band 1 559-1 610 MHz;
recommended that PL be operated through individual authorisations
no PL should be installed before the completion of those studies (e.g. close to airports);
only authorise PL with dedicated codes;
pseudolite installations should include guidance for reduction and reasonable checking of the
potential to cause interference.
ECC Report 183 Regulatory Framework for Outdoor GNSS Pseudolites
No ECC Recommendation!
ECC Report 183 clearly indicated outdoor GNSS PLs should not be allowed in airports or other
areas for aeronautical operations;
Only individual licensed and in 1559-1610 MHz.
ECC Recommendation (04)01
ECC Recommendation (04)01, amended in 2013: FORBIDDING THE PLACING ON THE MARKET
that jammers are designed to make the use of radio systems impossible in the areas
where they are placed;
that the legality of jamming has been discussed at several instances within the CEPT and
within the EU in the context of the R&TTE and the EMC Directives;
that these discussions have made it clear that there is no legal basis to allow that
communications be disrupted by jamming devices operated by the public;
that it is not possible to construct jammers that comply with the R&TTE or the EMC
Directive and therefore such devices cannot be legally placed on the market within the
European Union for use under these Directives.
CEPT Annual Interference Statistics
Unauthorised outdoor use of GNSS repeaters caused interference at airports in some countries.
Unauthorised use of jammers
Repeated use of GNSS jammers in trucks in order to avoid Electronic Toll Collection;
Mobile Service and GNSS jammers (e.g. in cases of theft to avoid conveyance of
positioning information of assets such as cars) ;
GNSS jammers equipment mostly imported from outside Europe.
CEPT is expecting the development of many new GNSS supported services and applications
(e.g. with dynamic maps in the transportation field, or ITS (Intelligent Transportation Systems
relying on GNSS positioning information), the interference situation has the potential to grow and
cause more problems in the future.
Important: Exchange and collection of information amongst national market surveillance and
enforcement authorities.
