(503) Precise Time without Internet: NTP Server from GPS Satellites

Time nuts are people deeply interested in exact timekeeping. They usually use atomic clocks to get to this holy grail. In today’s video, we will get precise time without internet access or a personal atomic clock. Instead, we will use 5-10 dollar GPS receivers. Fortunately, the atomic clocks we will use are paid for by other people.
