Περίληψη

Επεξεργαστήκαμε δεκαπέντε, GPS Ελληνικές καμπάνιες από το 1994-2001 σε ITRF2000 χρησιμοποιώντας το Bernese ν4.2. Το επίπεδο αναφοράς στελεχώνετε από 43 διεθνείς, με μακρά διάρκεια λειτουργίας IGS σταθμούς που περιλαμβάνονται στις τελικές συντεταγμένες μαζί με περίπου 280 τοπικούς σταθμούς. Οι ελάχιστοι δυνατοί περιορισμοί επιβλήθηκαν στις τελικές συντεταγμένες. Συνδιάσαμε 221 ημερίσιους SINEX φακέλους σε μια προσέγγιση ελαχίστων τετραγώνων με το TANYA πρόγραμμα δημιουργώντας τις χρονικές σειρές των συντεταγμένες και το πεδίο ταχυτήτων σε ένα Ευρώπη σταθερό ' σύστημα αναφοράς. Οι σταθμοί γύρω από την Χαλκιδική και τα Γρεβενά παρουσιάζουν υπολοιπόμενη κίνηση -lOmm/yr. Σταθμοί γύρω από την Αττική, Εβοια, ΝΑ Πελοπόνησο, νησιά του Αιγαίου εμφανίζουν μια ΝΔ υπολοιπόμενη κίνηση που φτάνει -40mm/yr στην Νότια Πελοπόνησο. Η περιοχή της Πάτρας δείχνει μια πιο νοτιοδυτική κίνηση σε σύγγριση με τις άλL·ς περιοχές -30- 35mm/yr. Η γεωδετική παραμόρφωση υπολογίζεται με δύο μεθόδους, αυτή των διακεκριμένων πολυγώνων και με την εφαρμογή μιας συνεχόμενης ελάχιστης καμπυλότητας επιφάνειας στο πεδίο ταχυτήτων
