IMPROVING THE SPATIAL ACCURACY OF POSITIONS MEASURED BY GLOBAL NAVIGATION SATELLITE SYSTEM RECEIVERS PLACED IN A SPATIAL CONFIGURATION

摘要

A method of improving spatial accuracy of positions measured by Global Navigation Satellite System (GNSS) receivers that are placed in a spatial configuration covering an area in which a deviation of a measured position from an actual position of each GNSS receiver is in the same direction is disclosed. The method comprises receiving the positions measured by the GNSS receivers in the spatial configuration, obtaining a map of planned positions of the GNSS receivers in the spatial configuration and comparing the positions measured by the GNSS receivers with the planned positions of the GNSS receivers to identify the difference between the measured positions and the planned positions. Finally, the measured positions can be compensated for this difference. When, after placement, it is not clear which object is placed where, the compensated positions can be used to identify the position of each specific object.
