Description

A distance meter with horizontal support structure

Technical Field

The utility model relates to the technical field of rangefinders, in particular to a rangefinder with a horizontal supporting structure.

Background technique

A rangefinder is a radio navigation device that measures the slant distance between an aircraft and a ground transponder. It consists of an airborne interrogator and a ground transponder. The distance between the two is determined by measuring the time required for radio waves to travel from the aircraft to the radio station. With the development of technology, laser rangefinders are now mostly used for measurement, which is convenient, fast and accurate. When the rangefinder is used in a complex environment, a support structure is required to maintain the horizontal state of the rangefinder.
