Satellite signal tracking method, position calculating method, and position calculating device

摘要

A satellite signal tracking method includes: detecting a situation of movement; calculating an error of the detection; and setting a loop bandwidth of a tracking filter, which is used to track a satellite signal received from a positioning satellite and of which the loop bandwidth can be changed, using the detection result and the calculated error.

主权项

1. A satellite signal tracking method comprising:
receiving a satellite signal from a positioning satellite; receiving a measurement of a situation of movement from at least one sensor; calculating an error of the measurement; determining a jitter of a tracking loop circuit, the jitter including a dynamic stress, the dynamic stress being calculated based on the measurement of the situation of movement and the error of the measurement, and the tracking loop circuit being used to track the received satellite signal; and setting a loop bandwidth of the tracking loop circuit based on the jitter.
