One band (1575.42 [MHz]) and L2 band (122

The mobile station receives and demodulates the ranging signals of the four satellites to obtain orbit information and clock information of the four satellites, and based on the information, obtains ranging signals of the four satellites and the mobile station. , The position of the mobile station can be calculated. Further, there is a type in which a 6-component force sensor is mounted on a mobile station and measures a distance and a direction during traveling. This six-component sensor measures the acceleration in the axial direction of the X, Y, and Z axes and the angular velocity around the axis, and measures the position using these measured values.

不都合を是正する位置測定方法を提供するものである。However, in the GPS, since the C / A code signal is used, the measurement accuracy has an error of several meters, and the same accuracy is obtained even when a six-component sensor is used. . In the measurement using the GPS alone, it is difficult to obtain an accurate running locus at fine time intervals. For example, in a mobile station traveling at high speed, the traveling distance in a very short time is long. Therefore, an accurate measurement method is required for each short time. Therefore, the present invention provides a position measuring method for correcting such a disadvantage.

め、誘導式等の説明を略す。However, the data obtained at the above time intervals is insufficient for a mobile station moving at high speed. Therefore, in the present invention, the interpolated values shown in FIG. 3B are obtained by using the 6-component force sensor at every position δt (20 ms) between the obtained time intervals Δt (= 200 ms). This interpolation method uses the values of the accelerations Xa, Ya, Za and the roll angular velocity P, the pitch angular velocity Q, and the yaw angular velocity R of the six-component force sensor, which are sequentially output within at least 20 ms, to calculate the operation shown in FIG. The calculation is performed by the data integration CPU and the data analysis CPU through the (equation 1) and (equation 2) shown in FIGS.
Since equations (1) and (2) are well-known coordinate transformation equations, explanations of the guide equations and the like are omitted.

This will be specifically described. First, the mobile station is initialized, and the roll attitude angle (φ0), the pitch attitude angle (θ0),
A yaw attitude angle (ψ0) is input, and a counter i is initialized (S0). Next, 1 is added to the counter i (S

The measurement interval of S is Δt (= 200 ms), which is a setting for obtaining correction data at δt (20 ms). Then, the value of the position (XEi, YEi, ZEi) of the mobile station is output, and the process proceeds to step 5 (S4).

Using the values of φi-1), the pitch attitude angle (θi-1), and the yaw attitude angle (ψi-1), the roll attitude angle (φ) and the pitch attitude angle (θ) that are coordinate-converted by (Equation 1) ), And obtains a differential value of the yaw attitude angle (ψ) (S5).

Then, a roll attitude angle (φi), a pitch attitude angle (θi), and a yaw attitude angle (ψi) are obtained (S6). Note that this integration method includes a method of simply adding data, a trapezoidal method, and the like, which are set based on a sampling cycle and a processing capacity. Next, the acceleration Xa, Ya, Za obtained from the 6-component sensor, the roll attitude angle (φi), the pitch attitude angle (θi), and the yaw attitude angle (ψi) are converted from the mobile station coordinate system to the earth coordinate system. Xa ', Ya', and Za 'are obtained by the following (Equation 2) (S7). Then, the obtained Xa ', Ya', Za 'are integrated (B) to obtain the speed X
