Title:
A satellite signal capturing method and a satellite signal capturing device
Document Type and Number:
Japanese Patent JP5974487
Kind Code:
B2
Abstract:
Every k (k¥2) sampling values from sampling values in a time series obtained by sampling a reception signal from a GPS satellite are selected, and addition-subtraction of the selected k sampling values is performed by changing the combinations of addition and subtraction. Using addition-subtraction result of a combination corresponding to time-series change in code values of replica code from among the combinations of addition and subtraction, the correlation result of the reception signal and a replica code is calculated. The satellite signal of the GPS satellite is acquired using the correlation result.
