Abstract

Techniques are provided for controlling a movable object such as a UAV. A baseline change between a controlling object and a controllable object can be determined with centimeter or sub-centimeter accuracy based on satnav measurements from the controlling object and the controllable object. The baseline change can be mapped to a state change for the controllable object. Control commands can be generated for effecting the state change for the controllable object.
