ABSTRACT:
A map plate for adjusting the angle of elevation of an antenna for use with an artificial satellite communication system is composed of a map in polar coordinates of the area of signal receiving points, a group of equi-angle elevation lines which are drawn on the map, a scale of the angle of elevation which covers the whole area of the signal receiving points, which is given on the circumference of the map, a pointer which is provided on the origin of the polar coordinates and a device connected to said pointer which interconnects the revolution of the pointer to the revolution of the antenna for adjusting the angle of elevation such that the angle of elevation of the antenna will reach a designated value by driving the antenna until the pointer reaches the designated value on the scale.
