Apparatus and method for super fine positioning with networks in tiered structure

A super fine positioning apparatus, comprising:

• a network module unit comprising a plurality of network modules each of which is configured to process a signal transmitted between a user terminal and a corresponding one of a plurality of communication networks, the plurality of communication networks having different positioning precision in a tiered structure;
• a network module control unit configured to select at least two of the network modules and couple to each of the selected network modules in an order determined according to the positioning precision;
• a positioning calculation unit coupled to each of the selected network modules through the network module control unit in the order and configured to calculate a location of the user terminal in each of the plurality of communication networks corresponding to the selected network modules in the order;
• and
• a database configured to store information about the user terminal and provide the network module control unit and the positioning calculation unit with the information.
