Abstract

Παρέχεται ένας πομπός σήματος πλοήγησης που μπορεί να διασφαλίσει, με χαμηλό κόστος, ότι η παρέκκλιση συχνότητας των επίγεια μεταδιδόμενων σημάτων πλοήγησης είναι μειωμένη. Ένας πομπός σήματος πλοήγησης λαμβάνει ένα μεταδιδόμενο κύμα, παράγει παλμούς συγχρονισμού, που είναι σύγχρονοι με τα προκαθορισμένα πλαίσια δεδομένων, παράγει μια θεμελιώδη ταλάντωση εσωτερικού ρολογιού με τη χρήση μιας μονάδας συγχρονισμού σήματος αναφοράς (550) με τους παλμούς συγχρονισμού που χρησιμοποιούνται ως σήματα αναφοράς, παράγει ένα σήμα IMES επί τη βάση της θεμελιώδους ταλάντωσης του εσωτερικού ρολογιού και μεταδίδει το σήμα IMES. Η μονάδα συγχρονισμού σήματος αναφοράς (550) περιλαμβάνει ένα κύκλωμα μετρητή (551), ένα σύστημα σύγκρισης (553), ένα φίλτρο ελέγχου χαμηλής διέλευσης (554), έναν μετατροπέα D/A (555) και έναν ταλαντωτή ελέγχου τάσης (556). Ο πομπός σήματος πλοήγησης χαρακτηρίζεται από το ότι όταν μια σχέση σε εύρος ανάμεσα στον αριθμό των παλμών ρολογιού που παράγονται από τον ταλαντωτή ελέγχου τάσης (556) με τους παλμούς συγχρονισμού που μετρούνται ως τα σήματα αναφοράς και μια τιμή αναφοράς σημειώνεται διαδοχικά εντός ενός προκαθορισμένου εύρους τιμών σε μια κατεύθυνση κατά έναν προκαθορισμένο αριθμό φορών, η μονάδα συγχρονισμού σήματος αναφοράς (550) ελέγχεται για να προσαρμοστεί το επίπεδο τάσης ελέγχου του ταλαντωτή ελέγχου τάσης (556).
