The advantage of using GPS Tracker for mining
GPS Tracking Device has proven a significant increasing in productivity and improved on-site safety in mining activities, e.g., mineral and aggregate extraction with especial incidence in iron ore and coal extraction and transport tasks. In open pit mining, accurate GPS and GNSS(Global Navigation Satellite System) is useful for tasks such as machine guidance, grading, dozing, drilling, collision avoidance, surveying, and fleet management. GPS can be used in open cut mining operations as long as the satellites can be viewed in a direct line of sight. Tests undertaken at two mines, under worst case conditions, show that GPS works well in most situations. Close to highwalls (within 3-4 metres) depending on the positioning of the satellites at any given time, the GPS system dropped back to two dimensional fixing, with only three satellites visible. GPS needs four satellites for a three dimensional fix. There are many areas where GPS technology can improve the productivity of coal mines.
