Abstract :
In this paper, low cost navigation sensor unit composed of three vibratory gyroscopes and two inclinometers and the DGPS was developed. The sensor can provide the position corrected by inclination, heading angle and roll/pitch inclinations. And the measured position was interpolated by the dead reckoning, because the sampling rate of the DGPS was 1 Hz. The accuracy of developed sensor unit was evaluated by field test on the flat field, gentle slope and bumpy road.
