Hi. I’m configuring my FMB920, and when I try to select Galileo as one of the GNSS sources that section becomes red, as if that was discouraged. Is there a reason we should not use that or Beidou? Just GPS and GLONASS appear blue when activated. Thanks

Hi,

To select Beidou you should select GPS and Beidou

Thank you. Would there be a reason not to enable 3 constellations? For example Galileo, GLONASS, and GPS.

I notice the default is just two, but I’m not sure if there’s a reason for that. Is this documented somewhere?

I know some GPS chips record samples at a lower frequency if 3 constellations are enabled, but I seem to be getting close to 1Hz whith 3 GNSS, which seems to be the fastest the configurator allows.
