Location Shift Algorithms in Open Pit Based on GPS

To solve the problem that location shift and statistics of carriage are not accurate when monitoring truck and statistics of ore carriage in the open pit by using GPS, the paper proposes a method to identify location shift and an algorithm to correct location shift, and it also designs a dynamic route generation algorithm of ore truck's carriage in open pit base on pheromone which can update open pit route maps automatically and make truck run on a relative standard route. It solves the problem of location drift and improves the precision of truck location and accuracy of carriage statistics. The algorithm is proved by practical application and data analysis in system.
