A method of mobile radio positioning aided by a single fan self-surveying laser transmitter (SF_SS_LT), wherein a rover comprises a mobile radio positioning system (Mobile_RADPS) integrated with a mobile laser detector; and wherein THE SF_SS_LT comprises a single fan laser transmitter and a positioning system integrated with the single fan laser transmitter. The method comprises: (A) performing self-surveying of the (SF_SS_LT); (B) generating a single fan laser beam by using the single fan laser transmitter; (C) detecting the single fan beam by using the mobile laser detector; and (D) timing the fan laser beam strike at the rover's location and using the timing of the fan laser beam strike at the rover's location to improve an accuracy in determination of position coordinates of the rover.
