| description | Movement information is calculated with high accuracy, without being influenced by the number of GNSS signals receivable by each of a plurality of antennas. A movement information calculating device 10 includes a plurality of antennas 21 and 22, a clock generator 30, a plurality of GNSS receivers 41 and 42, and an arithmetic logical unit 60. The plurality of antennas 21 and 22, each receives a GNSS signal. The clock generator 30 generates a clock signal. The plurality of GNSS receivers 41 and 42 are connected to the respective antennas 21 and 22, and share the clock signal from the clock generator 30 and calculate GNSS observed values by using the shared clock signal and the GNSS signals, respectively. The arithmetic logical unit 60 calculates movement information including a speed of a movable body based on the GNSS observed values from the plurality of GNSS receivers 41 and 42. |
