A RELATIVE POSITIONING METHOD

摘要

The invention relates to a method comprising receiving distances between a first and a second devices from the second device, wherein the distances are based on strength of wireless signals sent by the first device at two time points, measuring a heading angle and a moving distance of the first device between the locations at two points, receiving a heading angle and a moving distance between the locations of the second device at two time points, calculating angles between the devices at a two points by the first device on the basis of measured and received data, and determining the coordinates of the devices at two points. The invention further relates technical equipment implementing the method.
