A radio and light based 3-D positioning system comprising a stationary self-positioning radio (pseudolite) transceiver, a stationary laser transmitter positioned in a location with known coordinates, and at least one mobile integrated radio receiver (pseudolite)/laser detector (RR_LD). The stationary self-positioning radio (pseudolite) transceiver is configured to receive a first plurality of external radio signals, is configured to determine its position coordinates based on the first plurality of received external radio signals, and is configured to broadcast at least one internal radio signal. The stationary laser transmitter is configured to broadcast at least one laser beam. At least one mobile integrated radio receiver (pseudolite)/laser detector (RR_LD) is configured to receive a second plurality of external radio signals, is configured to receive at least one internal radio signal, is configured to detect at least one laser beam, and is 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}.
