Apparatus and method for determining positioning error range

A navigation apparatus (S) includes: a multi-path detection portion (102) which detects multi-path based on a pseudo-range; a pseudo-range error selection portion (103) which selects an error in the pseudo-range based on the detected multi-path and navigation data; and an error ellipse calculation p...

More Information
Summary:A navigation apparatus (S) includes: a multi-path detection portion (102) which detects multi-path based on a pseudo-range; a pseudo-range error selection portion (103) which selects an error in the pseudo-range based on the detected multi-path and navigation data; and an error ellipse calculation portion (104) which calculates an error ellipse based on the pseudo-range error selected by the pseudo-range error selection portion (103) and the received navigation data, and executes navigation processing based on a vehicle's own current position calculated by a positioning calculation portion (101) and the error ellipse calculated by the error ellipse calculation portion (104).
