Implementation of a Loosely Coupled Integration INS/GPS System using kalman filter based on Improved INS System ☆

The INS/GPS integration is an effective solution in multi-sensors navigation. This is because, GPS receiver and INS sensors can complement each other to achieve optimal results based on the advantages and disadvantages of them. In an information integration system from independent systems, the integration system achieve accuracy and better reliability based on information provided by each system is correct. This paper focuses on presentation of a loosely coupled integration INS/GPS using Kalman filter based on INS system has been improved the accuracy of IMU, object’s orientation. Testing results on land vehicle are shown the quality, accuracy and applicability of the proposed loosely coupled integration INS/GPS higher than tradition loosely coupled integration INS / GPS
