Title:
NAVIGATIONAL DATA PROCESSOR AND NAVIGATIONAL DATA PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2002098550
Kind Code:
A
Abstract:
To materialize the navigational system, high in precision and reliability, using the plural kinds of navigational equipment.
In an integrated navigator 120, the reliability of each navigational datum is judged by successively comparing and collating the navigational data measured by an inertial reference system 101 to a magnetic goniometer 110 judged normal with a three-dimensional coordinate system stored previously to a map database 140, and the navigational data required out of the whole navigational data measured by the inertial reference system 101 to the magnetic goniometer 110 judged normal are determined.
