Recommended settings for U-blox GPS RATE?

Hi,

Can someone recommend a GPS RATE for U-Blox modules and explain why we schould use it.
Any information is welcome!

I already have done some tests with U-Center and discovered that not all higher rates above the default are free from GPS glitches.

I wil post my findings here starting from default 1Hz to 10Hz.
(for some reason u-center was not happy with the 3Hz setting)

Anything less then 5Hz is invalid for flight on.

So in other words we have to have 5Hz and up for our course.

What about those GPS glitches you seen in the pictures, can we simple ignore it?

If you refer to the M8N documentation, 10hz is valid with one constellation(GPS or GLONASS), 5hz for two (GPS + GLONASS), 3hz for three (like GPS+GLONASS+GALILEO).

3hz is not a valid parameter in ardupilot settings.

Thanks for this clarification.

How about those glitches?

Could be jamming or interferences around your GPS Antenna,

Here is a screen of my M8N_Drotek antenna in my computer room (under roof window).

5 Hz is the recommended frequency with your GPS-GLONASS setting. It is normal (IMHO) to have drops at 10 Hz.
