NAVIGATION DEVICE, LOCAL DIFFERENTIAL GLOBAL POSITIONING SYSTEM AND COMPUTER RECORDABLE MEDIUM

摘要

A navigation device, local differential global positioning system and computer recordable medium are provided to cut down the cost by obtaining the desired location information without the high-precision navigation device. A location correction data are generated by using the high-precision navigation device and the general navigation equipment mounted in the standards moving body. The wireless communications unit(110) receives location correction data from the standard moving body by using the wireless telecommunication. The LDGPS(Local Differential GPS) part(120) calculates the first location information of the sub moving body by using the received location correction data and general navigation equipment. The INS(Inertial Navigation System) part(130) calculates the second location information of the sub moving body. The controller(140) calculates the location information of the sub moving body by using the first location information.
