MultiNav Pro+ GNSS 18Hz fix rate - is it sustained or does it drop under load?

Joseph MasonJune 13, 2026
So I've been running the GNSS module in a UAV application where I actually need that full 18Hz fix rate to stay consistent - not just burst to it occasionally. My concern is whether the module can genuinely sustain 18Hz continuously or if it throttles back when thermal load increases or when the fix quality drops (like partial sky view during a banked turn). I've seen other GNSS modules advertise max rates that are really more like "peak under ideal conditions" numbers, and you end up getting 10-12Hz in practice. Curious if anyone's stress-tested this over longer flight sessions, say 20-30 minutes continuous.
