Ultra-wideband positioning systems are widely used in such safety-critical industries as underground mining, open pit mining, metallurgy and others. The network of UWB anchors becomes large due to harsh industrial environment, making deployment time-consuming. In order to collect range measurement data and transmit it to the management server it is proposed to use the LoRa technology, allowing the UWB anchors be wireless and delivering robust deployment of the integrated system.

Simulation of the processing of navigation signals and estimation of the noise immunity of the receiver of an ultra-wideband positioning system in difficult conditions for receiving GNSS signals with dense taiga vegetation was performed. Experimental data were obtained on microwave interference and the conditions for the propagation of radio waves at real production facilities, including operating mountain taiga geophysical profiles.

Abstract-A device for clinical and domestic applications in cardiological studies is described.
