In this 4th part of this project we upgrade the software to give satellite data and frequency lock display. Plus the current frequency on the display is improved to give reading in MHz, KHz or Hz. The new software version can be downloaded from the link below: http://www.scullcom.com/GPS_Ref_Version6.zip PLEASE NOTE TO COMPILE THIS CODE YOU […]

Design & Build a GPS locked Frequency Standard – Part 3
In Part 3 of this project we will add a keypad for direct frequency entry and program the GPS module on the fly directly from the Arduino Nano. We will also add a battery check feature and make some changes to the original circuit. A new PCB design will allow all components to be on […]
Design & Build a GPS locked Frequency Standard – Part 2
In Part 2 of this project we will improve the reception of the GPS module and build the project on to printed circuit boards and test the unit. In addition we will look at ways of converting the 10MHz square wave to a sine wave. Below are links to download the schematics and PCB […]
Design & Build a GPS locked Frequency Reference Standard – Part 1
In this project we will design and build a 10MHz GPS locked frequency standard with additional outputs of 1MHz, 100KHz, 10KHz, 1KHz and 100Hz. The output frequency will also be present even when no satellite lock is available but will be free running. We will use a Arduino Nano and LCD display to indicate if […]
