摘要
The present invention relates to a method for obtaining the position of a moving object using an INS/GPS/ultrasonic speedometer combined navigation device, the method comprising the steps of: (a) obtaining an ultrasound-based velocity estimate for the moving direction of a moving object estimated using an ultrasonic speedometer; ; and (b) correcting the INS navigation information estimated by the INS using the ultrasound-based velocity estimate obtained in step (a), thereby obtaining the position of the mobile body based on the corrected INS navigation information. have.
