Opportunities to reduce random error satellite geolocation due to averagement of data received by U-BLOX NEO-6M-0-001 gps receiver with external active antenna

Abstract

In our time, problems of accurate positioning of objects, equipment and cargo arise more and more often. These are the tasks of logistics and precision farming and, a separate group of tasks, positioning during earthworks in construction: pits, arrangement of pile fields, etc. If a positioning accuracy of 10 m is quite sufficient for logistics tasks, monitoring the movement of transport and cargo, then for construction tasks, an accuracy of 10 cm is required, and building monitoring tasks require a millimeter accuracy. This work is devoted to increasing the accuracy of satellite geolocation by reducing the random error of the receiver. A budget receiver with a price of about $5 was chosen for the study, from which data on the current geolocation was recorded. The data from the receiver contains a random error, which was eliminated by averaging the result. Studies have shown that with small averaging intervals, the error remains, although it decreases; as the averaging interval increases, the error decreases, however, up to a certain width of the interval; a further increase in the averaging interval ceases to affect the magnitude of the error. It is optimal to average the results in the interval from 1000 to 2000.
