Abstract:
A calculation server estimates a position of a mobile terminal that communicates with a base station incorporated with received global positioning system satellite signals. The calculation server includes a positioning information analyzer configured to select one of the positioning modes to be used out of a cell/sector positioning mode and a hybrid positioning mode on the basis of a distance between a cellular base station and the mobile terminal, and a position detector configured to calculate the position of the mobile terminal in the positioning mode selected by the positioning information analyzer.
