Coordinate measurement in multi-beam drone positioning system

Abstract

The multi beam drone positioning system for automatic measurements of drone coordinates is presented. One part of this system is installed round a landing pad or a goods delivery pad. It forms a set of low-energy optical beams of definite shapes in three-dimensional space. Each beam transmits a digital code that characterizes its location relatively this pad. Second part of this system is a small set of miniature photodetector units that are fixed under a drone. The paper describes the technique based of the beam code analysis for calculation of drone coordinates relatively a landing pad. This system guarantees the accuracy that is necessary for accurate drone taking off, landing or goods delivery without usage of an expensive digital camera or a human operator. The advantages and possible applications of these sensors are also discussed.
