ABSTRACT:
A radio and light based 3-D positioning system comprising: a stationary integrated self-positioning radio transceiver/laser transmitter (RTR_LT) configured to receive a first plurality of external radio signals, configured to determine its position coordinates based on the first plurality of received external radio signals, configured to broadcast at least one internal radio signal; and configured to broadcast at least one laser beam; and at least one mobile integrated radio receiver/laser detector (RR_LD) configured to receive a second plurality of external radio signals, configured to receive at least one internal radio signal broadcasted by the stationary integrated self-positioning RTR_LT, configured to detect at least one laser beam generated by the self-positioning integrated RTR_LT; and configured to determine its 3-D position coordinates based on a set of data selected from the group consisting of: {the second plurality of received external radio signals; at least one received internal radio signal; and at least one detected laser beam}.
