The Loco Positioning Node is a versatile positioning device that can run either as an Anchor or Tag in a Loco Positioning system. The system measures the distance between Nodes and Tags, and from those distances, the absolute position of objects carrying Tags can be calculated.
For more information on the Loco Positioning System please see this Loco Positioning System page.
Specifications are based on the standard 2-way ranging mode.
