Abstract:
A navigation system is described comprising at least a first and a second navigation device (201A, 201B) that each is capable of determining an initial estimation (P1A, P1B) of their own position,—the first navigation device (201A) having a facility (225A) for transmitting its relevant navigation information (P1A) to the second navigation device (201B),—the second navigation device (201B) having a facility (225B) for receiving the relevant navigation information (P1A),—at least one of the first and second navigation device (201A, 201B) having a facility (210A, 210B) for providing a proximity signal (Spr, S′pr) that indicates whether the first and second navigation device are within proximity of each other,—the second navigation device having a dead reckoning facility (210B) for calculating the initial estimation (P1B) of its position and a facility (250B) for improving an accuracy of estimating its own position using relevant navigation information (P1A) provided by the first navigation device (201A) for positions for which the proximity signal (Spr) was given.
