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. For example, the aforementioned values A1, B1, C1, B2, and C2represent values such as TTick1, RTC1, TOW1, RTC2, and TOW2, respectively.
