Hello.
I have been using the Sparkfun RTK Express GPS for a few months now and it has been working great. However, since the arrival of winter and the temperatures are low (<5°C), it no longer receives signals from satellites (although it turns on correctly).
What is the temperature limit for GPS use?
My problem may be more related to the antenna than the Sparkfun RTK Express device?
Thank you for your help!

I have used a Facet at 0 degree with no problem.
I would say look at the antenna.
it no longer receives signals from satellites (although it turns on correctly).
The device is rated to operate down to -20F. I agree with amlago. It sounds like the Express is fine but the antenna may have a problem.
Oddly, I just got my RTK Express Plus and it could see several satellites from inside the house and after walking outside with it and walking around the porch for a few minutes in the 24 °F temps it stopped seeing satellites. I have factory reset the RTK and checked the ant connection and still nothing. Running RTK firmware v3.2
