ABSTRACT:
A method for obtaining GNSS time in a GNSS receiver includes: deriving a relationship between a first clock signal and the received GNSS time; latching a second clock signal and the first clock signal at a first latching point to obtain a clock value A1of the first clock signal and a clock value B1of the second clock signal; calculating a GNSS time C1corresponding to the clock value A1according to the relationship; latching the first clock signal and the second clock signal at a second latching point to obtain a clock value A2of the first clock signal and a clock value B2of the second clock signal; and calculating a GNSS time C2corresponding to the clock value A2according to the GNSS time C1, the clock value B1, and the clock value B2.
