Experimental multi sensors navigation system research

Given research work presents the possibilities of efficient multi sensors use to increase accuracy of vehicle position parameters estimation. First is preview of possibility to combine multiple low cost GPS devices and MEMS acceleration sensors. Then practical experimental results are presented. In second test complex navigation system is supplemented with gyroscope to eliminate GPS and inertial sensor weaknesses. Objective. Determinate the effectiveness of several sensors use to improve accuracy of vehicle motion parameters. Devices used - multiple GPS receivers (MTi-G Xsens GPS, BU-353 GPS), MTi-G Xsens (accelerometer and gyroscope) and multiple accelerometers (Steval MKI024V1 and Steval MKI006V1).
