Design of a navigation system using GPS and dead-reckoning

摘要: In this paper, an integrated navigation system based on GPS(Global Positioning System) and Dead-Reckoning (DR) is designed. For the calibration of DR, a self-calibration method GPS-based are proposed. From field-test results, it shown that DR can be successfully calibrated by two proposed methods. Also, cascaded filter approach mixed-measurement algorithm employed for GPS/DR integration. By using newly algorithm, in simulation position error becomes smaller than only even if number visible GPS satellites less 4.
