Patent attributes
A navigation satellite system includes a first electronic device that decides, based on received GNSS correction data, integer ambiguity in a difference between a first carrier phase of a first radio wave received by a fixed station and a second carrier phase of a second radio wave received by the first electronic device to calculate a path difference between the first radio wave and the second radio wave. The system also includes a second electronic device that calculates, based on the GNSS correction data, a difference between a third carrier phase of a third radio wave received by the second electronic device and the first carrier phase received from the first electronic device and calculates, by using the integer ambiguity, a path difference between the first radio wave and the third radio wave to calculate second relative coordinates of the second electronic device with respect to the fixed station.
