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...
