I have a project that requires a very accurate timestamp measurements at different remote location connected by an LTE modem, sending data to the cloud using MQTT messages.
I was thinking of using a Raspberry Pi with a GPS board to set up a Stratum-1 server as set up on this guide to keep the internal clock accurate:
https://www.ntpsec.org/white-papers/stratum-1-microserver-howto/
and use a sensor connected to a USB port to take my measurements.
I have a prototype running on Raspbian, but would like to use a resin.io to manage the multiple devices and was unsure how to build the stratum-1 NTP server into a docker image.
Any pointers on how to do this?
Thanks in advance.
