Περίληψη
Το Γεωδυναμικό Ινστιτούτο του ΕΑΑ ξεκίνησε γεωδαιτικές παρατηρήσεις το έτος 2006 με την ίδρυση και λειτουργία του μονίμου σταθμού αναφοράς ΝΟΑ1. Σήμερα το δίκτυο ΝΟΑΝΕΤ αριθμεί 20 μόνιμους σταθμούς (σε συνεργασία με τρίτους φορείς) με βήμα δειγματοληψίας το 1-s και σε σύνδεση πραγματικού χρόνου με το κέντρο συλλογής και αποθήκευσης των δεδομένων (Αθήνα, Θησείο). Αυτή η εργασία παρουσιάζει την διαδικασία συλλογής και επεξεργασίας των δεδομένων GPS, λαμβάνοντας υπόψη τα περιοδικά σήματα (ετήσια και ημιετήσια) που υπεισέρχονται στις χρονοσειρές και δίνοντας σφάλματα στις εκτιμήσεις των ταχυτήτων με ανάλυση ενός μοντέλου θορύβου. Τέλος, παρουσιάζονται αποτελέσματα στο ITRF2005 για τους σταθμούς εκείνους των οποίων η διάρκεια καταγραφής έχει ξεπεράσει τα τρία χρόνια, γεγονός που εξασφαλίζει αξιόπιστες τιμές ταχυτήτων.
