ABSTRACT:
Methods and systems for determining a position and an orientation utilize a radio frequency signal transmitted from an effective source location which moves along a first closed, non-planar path. The closed, non-planar path has a plurality of local extreme points with respect to a predetermined axis. The radio frequency signal is received at an effective receiving location which may, optionally, move along a second closed, non-planar path. A phase signal representative of the phase of the received radio frequency signal is detected. The phase signal is filtered and processed to form at least one signal quantity representative of elevation, bearing, and/or orientation.
