发明名称 METHODS AND APPARATUS FOR OBTAINING ACCURATE GNSS TIME IN A GNSS RECEIVER
摘要 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 A1 of the first clock signal and a clock value B1 of the second clock signal; calculating a GNSS time C1 corresponding to the clock value A1 according to the relationship; latching the first clock signal and the second clock signal at a second latching point to obtain a clock value A2 of the first clock signal and a clock value B2 of the second clock signal; and calculating a GNSS time C2 corresponding to the clock value A2 according to the GNSS time C1, the clock value B1, and the clock value B2. For example, the aforementioned values A1, B1, C1, B2, and C2 represent values such as TTick1, RTC1, TOW1, RTC2, and TOW2, respectively.
