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: Provided is an information processing device comprising: a processing unit that dynamically sets an area in a portion of the surroundings of a first terminal including the position of the first terminal on the basis of a state of a moving body mounting the first terminal and the position of the first terminal and determines entry of a second terminal into or approach of the second terminal to the area; and a communication unit that transmits, to the second terminal, a signal for causing the second terminal to issue an alarm in response to the entry or the approach.

Abstract: The present application: receives positioning data from each of a plurality of positioning terminals that have received positioning signals transmitted from a plurality of satellites; uses the received positioning data to detect, for each satellite, the difference between the positioning signal reception quality at a first positioning terminal and the positioning signal reception quality at at least one second positioning terminal; and uses the difference for each satellite to determine a satellite to be used for positioning computation for the first positioning terminal.

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.
