NELS and Loran C
The service offered by NELS will
not be available after 2005
Some of the NELS members
countries think that this system no
longer corresponds to the users
needs
NELS did not care of the market
This will result in a dramatic loss
of knowledge and working ability

NELS and “enhanced Loran”
1999 : NELS statement on
the integration of systems
2001 : implementation of
Eurofix in four stations
2002 : development of new
receivers

Galileo and Loran C
Before 2003, the questions
were often :
 is Loran
Galileo ?
fighting
with
 will it be enough money ?
Now, as the Galileo project
is well going on :
 it is easily accepted to
heard about Loran
 but there is a tremendous
amount of work to be done

Some European countries and
“enhanced Loran”
Germany has implemented
a Eurofix monitoring station
The
United
Kingdom
submit a note on vulnerability
and back up of GPS to the
European Maritime Safety
Agency
Blue : NELS members
Red : country asking to join NELS
Green : countries interested by NELS

ERNP and “enhanced Loran”
European wide service provision
Spectrum policy
European Radio Navigation Plan
Promotion of
international standards
Assistance in developing and
siting of radio navigation aids
Evaluation along common
elements and coherent funding
policy
Assistance to member States

B - GNSS back-up and “enhanced Loran”
An important part of the debate to have on
“enhanced Loran” is the back-up role. :
 what is understood by back-up to GNSS ?
 does GNSS need a back-up ? If so, what is
the justification ?
 do Loran C and Chayka qualify to provide
the services required ?
The EMRF has been asked by EC to
extend the Dr Ward study on “GNSS
vulnerability and mitigation measures “ to all
kinds of marine aids to navigation

France and Loran C
Loran C directly concerns two Ministries :
 the Ministry of Defence owns the two
stations and the Control Centre
 the Lighthouses and Buoys Division of the
MITHTS manned the two stations
The users were mainly in the maritime
domain

ILA Convention and Technical Symposium
11
France and “enhanced Loran”
The Ministry of Defence
decide to maintain and use
Loran C until 2015 for his own
purposes
The
Ministry
of
Infrastructures,
Transport,
Housing, Tourism and the Sea
decide
to work
on the
advantages of “enhanced Loran”
for terrestrial users

French proposal
France is trying to implement a
new system
It is a minimal concept, allowing
to every interested country to join the
project :
 Lessay and Soustons
 Ejde (running costs payed by
France)
 Sylt (taking in account the
German project)
 Sellia Marina (renovated with
the Loophead acquired equipment)
Contribution of Megapulse

French proposal
(2)
Due to the baselines
distances between Soustons
and Sellia Marina, and Sylt
and Sellia Marina, options to
implement a new stations have
to be studied, in :
 Provence
 Alsace
 Lorraine

Actions
At the NELS level
The NELS figures must be the best as possible
Proposals of actions to reduce the gap with what is mandatory
must be made and implemented
The External Time References equipment must be implemented
in all the stations
The NELS CAO must give all the needed information about
Loophead equipment status and cost sharing
METLTM – DAMGM
ILA Convention and Technical Symposium
15
Actions (2)
Decided by France
Technical analysis about the implementation of a new chain
including Sellia Marina to be made
Draft report on the expected performances of the SELS chain,
and the costs of the project to be prepared
Budget a new station in 2004 to be found
Research of land possibilities to be done
Letters to the German, Italian and Dannish NELS members
representatives, to launch the technical work, to be sent
METLTM – DAMGM
ILA Convention and Technical Symposium
16
Actions (3)
To be proposed by France
Technical meeting between :
 Denmark
 Germany
 Italy
 France
to be organise in January 2004, to validate the draft reports
