Abstract: This article is the first part in a series of research papers studying the location systems used in coal mines. The paper reviews various approaches to investigation of location systems and assesses the impact of external factors on the location accuracy in the systems created using complex measurement techniques. The tests were performed at different mine sections, i.e. straight roadways, junctions and turns, equipped with the SBGPS system. First, planned actions were performed in the mine, e.g. positioning of the test objects in defined locations, moving along designated routes, etc. Following which, the raw (mathematically unprocessed) data of distance measurements using the ultra-wideband signal Time-of-Flight (ToF) method was downloaded from the system’s server and analyzed with account for the actual position of the test objects at various time points. Smart Caplamp were used as the test objects. Nodes of the system’s data communications network - base stations - served as the nodal points with the known location that were used as the reference points for position determination.

The tests proved high accuracy of the positioning systems as well as their stability towards multipath signal propagation and other specific features of the mine environment. The performed analysis helped to collect the data needed to compile a mathematical model of the positioning system.

Keywords: location system, positioning, accuracy, coal mine, model
