Can the u-blox API tell which GNSS satellites are visible?

I have an Arduino sketch that is outputting location info from a ZOE-M8Q. Its telling me that it has 20 satellites in view. These can’t possibly all be GPS satellites and must include some BeiDou and/or GLONASS. Is there any way to show how many of each type of satellite the board can see?

Thanks.

Hi Matt,

Please try this example:

Very cool! Here’s my output from that:

08:32:12.159 → New NAV SAT data received. It contains data for 27 SVs.

08:32:12.265 → GLONASS 21

I’d never even heard of QZSS before, which is a Japanese system. I’m in the northwest corner of Washington State.

Thanks.
