Abstract
The aim of the work is to develop methodologies based on ultra-wideband positioning to create systems for the mutual positioning of moving objects. For this purpose, positioning errors in ultra-wideband radio navigation in the presence and absence of a direct signal propagation line between the radio tag of a mobile object and a base station are shown in the article. In presence of difficulties, pseudorange measurements acquire a displacement error. The construction of positioning systems using the ranges between radio tags (interpersonal channel) is proposed in the article. Construction of schemes based on radio channel models of copper mines shows that there is no error in the displacement of the RFID tag range, which is defined as the sum of the ranges by the intermediate RFID tag. With a low speed of movement of an intermediate RFID tag and a high frequency of range measurements, the intermediate marker can be represented as a fixed base station. The broadcast format of RFID signals will allow avoiding collisions on the air.
