This accurate clock project is developed based on the GPS Receiver which captures a time signal from the U.S. government’s global positioning system (GPS) satellites and parses it to extract time syntaxes from NMEA string to finally display on 7-segment displays. The transmitter on GPS clock then broadcasts the time to every other nearby [...]

In this project a 16-bit PIC is used to build an accurate frequency reference synchronized to a GPS clock. This device can serve as an accurate frequency counter that can count to 50 MHz with 1 Hz accuracy. It can also be used to generate GPS-locked output signals as a frequency reference or as [...]
