ULTRASOUND EMITTING AND RECEPTING MODULES FOR A LOCAL POSITIONING SYSTEM

Abstract

Positioning systems are now widely used in various fields of human activity. They allow with a certain accuracy to determine the position of an object in space. There are global positioning systems that use satellite signals for this purpose. Their disadvantages are relatively low accuracy and difficulties in premises. Local positioning systems have higher accuracy and can be used in any premises and territories. During the work on the article, modern methods and solutions used in the construction of local systems for determining the location of the object were analyzed. A model of a local positioning system based on ultrasonic modules has been proposed and built. As a result, a structure and working model has been developed in the form of devices for emitting and receiving an ultrasonic pulse with a high sensitivity and a wide solid angle of reception / emission of ultrasound, which can be successfully applied in a local positioning system. For the further development of this system, it is necessary to additionally include in its composition duplicate methods of measuring location. For example, the lidar module.
