Abstract

PURPOSE:To enable the calculation of relative positions at two points in two adjacent UTM coordinate systems by converting UTM coordinates. CONSTITUTION:Two UTM coordinate systems are established as L(XL-YL) and M(XM-YM) coordinate systems and A and B as points in the L and M coordinate systems respectively. The L and M coordinate systems are separately move parallel to make the coordinate systems with the points A and B as origin respectively, as XA-YA and XB-YB and then, done so again to make the coordinate systems with a desired point C as origin on the boundary as X'A-Y'A and X'B-Y'B separately so that the coordinates (x0, y0) will be determined for the point C on XA-YA and those (x1, y1) for the point B on X'B-Y'B. The angle between the boundary and Y'B axis at the point C is set at beta. Since the L and M coordinate systems are linearly symmetrical with respect to the boundary, beta is given to the angle between the boundary and the Y'A axis. Therefore, the angle alpha between X'A-Y'A and X'B-Y'B equals 2beta to enable the point B to be translated to the coordinates (x2, y1) of X'A-Y'A. Thus, by the addition of the coordinates (x0, y0) at the point C on XA-YA thereto, the coordinates of the point B expressed by the M coordinate system is translated to the coordinates (x, y) in the L coordinate system.

If the aircraft and the object are in one UTM coordinate system, the relative positions of the aircraft and the object can also be easily calculated because the UTM coordinate system is a coordinate system that represents absolute position. However, as mentioned above, Japan is covered by four UTM coordinate systems, and if the aircraft and the object are in different UTM coordinate systems, it is difficult to determine the exact relative position of the aircraft and the object. It was not possible to do so, and almost no countermeasures were taken. Therefore, conventionally, the UTM coordinate system has not been used for aircraft control or for determining the relative position between two points on the ground in different UTM coordinate systems.

Define the coordinate system where the L coordinate system is translated in parallel and point A is the origin as the x, -yA coordinate system, and the M coordinate system is translated in parallel and the coordinate system where point B is the origin is defined as the XB-YB coordinate system. . Now, move any one point C on the boundary of the L, M coordinate system (hereinafter simply referred to as the boundary) and the D, L coordinate system to create a coordinate system with point C as the origin in the XA-yQ coordinate system. , and move the M coordinate system in parallel to point C
A coordinate system with the origin as the xB'-yB' coordinate system is defined.
