As i am working on my own GPSDO project i had multiple of these Trueposition GPSDO modules, for using them correctly i put them into enclosure. here is how whole project goes.
Distribution Board
Detailed description of GPSDO board is available here
10Mhz Distribution board has PIC18F25K50 micrcontroller which is running firmware perform usb to serial conversion and at the same time sniffer incoming packet from GPSDO module for the status information , Display pared data on to OLED and LEDs, Firmware also handle User interface key press and menu display.
It is possible to start a survey right on the front panel board using key press.
Front Panel Display Board
Keypress
Normal state
Short : switch between home screen and coordinate display
Long press : Get into survey menu.
Press and hold : not used
In survey menu
Short : incremt survey duration.
Long press : Get out of survey menu.
Press and Hold : start survey for selected duration
All PCB Source , schematic source and Firmware are available in my gihub.

Hello Gaurav
ReplyDeleteCan you provide an assembled GSPDO face board you've used with this project? Then i can buy the distribution and the face boards together.
All the best!

Hello!
ReplyDeleteLike many HAM's, I use the Trimble Thunderbolt GPSDO. It is a pity that this project does not apply to this device. However, I would like to use a 10 MHz distribution amplifier to split a single signal from my GPSDO. I hope your layout will be good for this.
