==Description==<br />
<br />
Navigation in a relative frame of reference, locked to a beacon on a (moving) base platform. We're going to explore navigation by radio beacons, like VOR, ILS for drones, e.g. BLE beacons, adding directional info through multiple beacons (data-separated). And we are going to explore angle-of-arrival options in Bluetooth.<br />
<br />
<br />
==Improvements==<br />
<br />
Current state-of-the-art is: AR tags with ranging based on size, Radio beacons using signal strength as ranging, in the aviation sector, there is the concept of VOR (radio-beacon with ranging based on echo delay)<br />
