Abstract: The present disclosure is effective in easily estimating an integer value bias at a high speed. A processor of a positioning system, a positioning method, and a positioning station performs interference positioning through calculation processing based on positioning data of the base station and positioning data of the positioning station. A plurality of calculation processing items are performed in parallel with different time points as start time points. Thus, even in a case where a situation in which the time required for the calculation of a fix solution differs depending on time point at which time point the calculation processing starts, there is a possibility that one of a plurality of calculation processing items can calculate the fix solution at an earlier time than in a case where single calculation processing performs the calculation. Therefore, it is possible to easily estimate the integer value bias at the high speed.

Abstract: A positioning system includes a receiver that receives a positioning signal from a positioning satellite and generates carrier phase information, a base station that receives the carrier phase information from the receiver, and a communication terminal that performs wireless communication with the base station. The base station transmits information including the carrier phase information and the position information of the receiver as a carrier positioning signal to the communication terminal and the communication terminal performs carrier positioning using the carrier positioning signal transmitted by the base station. Here, the base station encrypts the position information of the receiver, in the carrier positioning signal to be transmitted.
