The EUREF Technical Working Group
(EUREF TWG) is responsible for the general management of the EUREF Permanent Network.
The TWG develops directives, policies and priorities for the EPN and communicates
them to the EUREF community through the Resolutions of its annual symposia.
Guidelines for the Coordination of the EPN activities
by C.Bruyninx, EUREF TWG Meeting, Tromsoe, June 21, 2000
The EUREF Permanent Network (EPN) consists, in addition to the three
network components (stations, data centres and analysis centres), of :
Coordination Group
The tasks of the Coordination Group are to :
- coordinate all activities related to the permanent network
- propose policy to the EUREF TWG
- control general activities of the EUREF permanent network
- propose and coordinate new projects
The Coordination Group (CG) of the EUREF permanent network consists of :
- Network Coordinator
- Data Flow Coordinator
- Analysis Coordinator
- Project liaisons
- EUREF TWG representative
The CG will meet at least once a year. Members make a minimal commitment for a period of 4 years.
Central Bureau
The Central Bureau of the EUREF permanent network is responsible for the day-to-day general
management of the EUREF permanent network consistent with the directives, policies and priorities
set up by the EUREF TWG. The network coordinator is responsible for the management of the EPN
Central Bureau.
The institute hosting the Central Bureau of the EUREF permanent network (and network coordinator)
makes a minimal commitment for a period of 4 years.
Projects
Projects are set up by the Coordination Group for a minimal period of 4 years in order
to introduce new applications into the EUREF permanent network or study special aspects of the
permanent network. After the first 4-years term, the Coordination Group will decide to maintain
the Project or to include it into the routine EUREF permanent network applications and products.
Task Descriptions
Central Bureau/Network coordinator ***************
The Network Coordinator is, as head of the EUREF permanent network Central Bureau (EPN CB),
responsible for the general management of the EUREF permanent network, and
- Maintains the EPN CB and performs a long-term coordination role to ensure that EUREF participants contribute to the service in a consistent and continuous manner and adhere to EUREF standards
- Verifies that the EPN CB receives and all information about sites, centres, networks, data flow, data holdings, product generation, product availability, addresses. Makes this information available to the user community.
- Instructs new sites/centres about EUREF/IGS standards and coordinate their introduction in the network
- Coordinates the topology of the network: stations to be included/excluded, allocation of stations to data centres (together with the data flow coordinator) and to analysis centres (together with the analysis coordinator).
- Coordinates the flow of information towards the International GPS Service (IGS) and other organisations.
- Interfaces with the IGS to assure the compatibility of IGS and EUREF and the collaboration in projects of common interest
- Preserves harmonisation of standards between EUREF and the IGS
- Coordinates between the EUREF Projects
- Organises reports, workshops and meetings dealing with different aspects of the permanent network
- Reports to the EUREF Technical Working Group and prepares, in collaboration with all participating agencies, a yearly report.
- Publishes documents required for the satisfactory planning and day-to-day operation of the Service, including standards, guidelines and specifications
Data Flow Coordinator ***************
- Assists operational centres / stations with the organisation of the data flow and the data quality check
- Coordinates activities between operational centres and data centres
- Provides to the data centres the necessary guidelines and procedures to monitor data availability and data quality
- Monitors the routine data flow through the EUREF permanent network, identifies problem areas and takes the necessary actions wherever necessary
- Organises the data flow for new stations (in collaboration with the Central Bureau)
- Organises and monitors the data flow related to applications which need a different data availability (faster turnaround of higher sampling rate) taking into account existing EUREF standards and structures and this in collaborayion with the members of the Executive Board
- Organises alternate data flows
Analysis Coordinator ****************
- Assists the analysis centres
- Combines the products of the analysis centres and generates a verified unique EUREF product (station coordinates in SINEX format)
- Monitors the analysis centres solutions and take whatever actions are necessary to ensure the routine generation of consistent subnetwork solutions
- Supervises the generation, updates and distribution of processing strategies
- Monitors the flow of the products towards the IGS
- Coordinates the generation of a yearly RNAAC report to the IGS
- Produces yearly a multi-year network solution for the IERS
- Reports station irregularities that show up at the combination level to the Network Coordinator
- Appoints investigators for special problems related to deviating results
Project Liaison **************
- Is responsible for the coordination of the activities related to this Project
- Issues the necessary "Calls for Participation" to organise the participation of the three EUREF permanent network components
(Stations, data centres and analysis centres) to the SP. Submits the results of the "Call for Participation" to the Coordination Group and proposes an Action Plan.
- Develops procedures and takes the necessary actions for the three network components to participate in the Project.
- Takes the necessary steps to generate an unique and validated EUREF Product.
