EUREF Permanent Network
EUREF Permanent Network (EPN) is a European Network of more than 200 continuously operating GNSS reference stations with precisely known coordinates referenced to the ETRS89. EPN is the key instrument in the maintenance of ETRS89 geodetic datum. The EPN stations collect continuously the observation data from high accuracy GPS/GLONASS receivers. The data is processed in the centralized way in a few data processing centres. EPN is created and maintained by a voluntary agreement of about 100 European agencies and universities. EPN activities are coordinated by EUREF.

Famous quotes containing the words permanent and/or network:
“A country whose buildings are of wood, can never increase in its improvements to any considerable degree.... Whereas when buildings are of durable materials, every new edifice is an actual and permanent acquisition to the state, adding to its value as well as to its ornament.”
—Thomas Jefferson (1743–1826)
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
