Introduction
The CSL RTLS solution is based on the application of time of arrival technology.
In the RTLS, an anchor is the device installed in a known position inside a zone,
normally, at the corners of the zone. The moving sensors within the zone can measure
the range to each anchor so as to obtain the absolute positions inside the zone.
In a minimum RTLS system, 4 anchors are installed in a zone. However, the more the
anchors are installed, the higher the accuracy of the sensor position to be obtained.
The accuracy of positioning is +/-1 meter.
