Abstract
A telescope includes a position determining system for receiving positioning signals from GPS satellites to obtain the present position of the binocular. A relative-position calculation system provides for calculating a distance, an altitude difference, and an azimuth angle between the telescope and an external device based on the present position of the telescope and the position information of the external device. The telescope further includes an indication system which indicates, by a displaying device, the values of the distance, altitude difference and azimuth angle.
