Pozyx Indoor Navigation (navigation without GNSS / GPS)
Alternatively, a Pozyx system can be installed in rooms without stable reception. The anchors should be placed in a rectangular shape. The anchor with the lowest ID will act as the “origin” and should be placed at the lower left corner of the rectangle. Each of the remaining three anchors should be placed in a corner so that if you run an “N” pattern inside the rectangle, the anchor IDs will increase. The configuration is a little easier if the line from the origin anchor to the 2nd anchor is north, but it is not necessary as the parameter BCN_ORIENT_YAW can be used to account for this difference.
