Ad hoc positioning system using angle of arrival

Typically, a few nodes of the network know their location – landmarks (equipped with GPS);
The rest of the nodes can communicate to other nodes;
Every node has a capability to determine the angle of the arriving signal;
Every node in the network has fixed main axis to measure all angles against it.
Every node can only communicate with its neighbors within the radio range (they may not know their location).
