Lost FIX - How to interpret the results

Hi everybody,

Yesterday I tried to walk with reach

I have the base on my roof. The base sends the corrections to the rover via NTRIP protocole, and the rover use the connection of my phone.

The firmware version of ReachView is v2.2.5

Sometime I lost FIX statut but I don’t understand what’s wrong when I read the post-processing data.

Base to the left and rover is right window

Do I miss something?

Thanks for your help.

A slightly downgoing AR before that yellow period.
From what i could see of the log, sat nr 20 and 25 is dropping on the SNR level. What causes this is a another story
