Abstract. The article presents an analysis of patent research to control the quality of ballast compaction from electromagnetic to empirical. The principle of operation of ballast compaction control systems based on GNSS (SCUB) is shown, which is based on the determination of current coordinates from two satellite antennas using satellite equipment with advanced functionality with differential correction from the satellite reference network during compaction (in dynamic mode). The advantages and disadvantages of this system are determined.
