Description: I have for your consideration, this compact, new, Arduino based GPSDO. It uses a ATGM336H GPS to control a CTI OSC5A2B02 OCXO. This is a new build using US sourced (Mouser) components and shipped from the USA. The 10 MHz Square Wave Reference Signal can be used to control your frequency based test equipment or radios. It has an exceptionally clean, low phase noise signal that is accurate to approximately 0.001Hz. The nice compact aluminum enclosure comes in at 106x88x34mm The PLL control is accomplished using an Arduino Nano that can be powered and monitored via computer using a usb c connection (Remove the top of the case and plug the Arduino into your computer using a usb c cable. Using Arduino IDE software, you can monitor the output performance characteristics and make adjustments to the gain and other parameters.) Note: this requires knowledge of Arduino programming and GPS control systems but is not necessary for use. Simply plug in the unit, allow the GPS to obtain a lock, and the device is ready for use. This design is based upon the excellent Lars GPSDO and extensive information about this design can be found online. The pcb board also has pinouts to connect to, monitor, and adjust the GPS module as well as the Arduino Nano. A USB-TTL module is required to accomplish this. To setup for use: connect and place antenna in area with good view of the sky and plug in the unit. Once the GPS locks onto several satellites and the OCXO warms up (~15 minutes) the reference signal will self calibrate and the “GPS Lock” LED will light up. The GPSDO can then be used. LED Status: Blinking: Acquiring satellite lock Off: Satellite lock completed, acquiring OCXO lock Solid: GPS & OCXO locked, ready for use What’s included: GPSDO, power cord, GPS antenna. What’s NOT included: any additional hardware shown for demonstration purposes (frequency counters, oscilloscopes, etc). Anything not specifically listed in “What’s included“
