1. A system for determining an orientation in space of a linear array of radio receivers in a workspace comprising:
a. a primary radio receiver capable of measuring phase of arrival of a received signal;
b. a secondary radio receiver capable of measuring phase of arrival of a received signal, located a first distance from said primary radio receiver;
c. a plurality of radio transmitters positioned in the workspace at known, fixed locations relative to the primary radio receiver; and
d. a processing unit in communication with said primary radio receiver and said secondary radio receiver, said processing unit capable of calculating an angle between each of the plurality of radio transmitters and an axis comprising a line passing through the primary radio receiver and the secondary radio receiver, and capable of calculating an orientation determination algorithm.
