Positioning apparatus and positioning method

Abstract

A positioning apparatus includes: a unit that calculates an inertial navigation positioning result by performing position calculation using inertial sensor data and stores the inertial navigation positioning result in a storage unit with time information being added to the inertial navigation positioning result; a unit that calculates a GPS positioning result by using GPS positioning data; a unit that performs a coupling process for the GPS positioning result and the inertial navigation positioning result, which is stored in the storage unit, having the same time information as time when the GPS positioning data is acquired; a unit that corrects the inertial navigation positioning result stored in the storage unit based on information of a position error, an attitude error, a velocity error, and a bias error of the inertial sensor that are acquired through the coupling process.
