Provided is a mobile unit orientation sensor device which can perform correction of angle offset error derived from an angular velocity sensor, even during travel of the mobile unit, and which can detect the orientation of the mobile unit with a high degree of accuracy. It is possible to perform angle offset error correction by means of zero-point drift of an angular velocity sensor (101), using only the angle of orientation of the GNSS sensor (103). The angle of orientation acquired from the GNSS sensor (103) may be acquired while the vehicle is travelling. As a consequence, it is possible toacquire, with a high degree of accuracy, the angle of orientation with an angular velocity sensor (101) for measurement objects such as vehicles, for which it is difficult to accurately measure the angle of orientation, without requiring the vehicle to stop. It is therefore possible to calculate positions on a two-dimensional map with a high degree of accuracy using a locator MCU (105). It is possible to perform correction of angle offset error derived from the angle velocity sensor (101) while the mobile unit is traveling, and it is possible to detect the orientation of the mobile unit witha high degree of accuracy.

    本发明实现一种可以在移动体的行驶中执行源于角速度传感器的角度偏移误差的修正、能够检测高精度的移动体的姿态的移动体的姿态传感器装置。本发明可以仅使用GNSS传感器(103)的方位角来执行角速度传感器(101)的零点漂移造成的角度偏移误差的修正。从GNSS传感器(103)获得的方位角在汽车的行驶中也能获取。因而,即便是对于汽车这样的难以准确地测量姿态角的测定对象,也能利用角速度传感器(101)来高精度地获得姿态角而无须停下汽车,因此能利用定位用MCU(105)来高精度地执行二维地图上的位置计算。可以在移动体的行驶中执行源于角速度传感器(101)的角度偏移误差的修正,能够高精度地检测移动体的姿态。
