I get the error when trying to arm though my position is correct, 13 satellites, hdop and vdop look good.
I have a Pixhawk 2.4.8, an M8N GPS, and haven’t ever armed due to the error.

At the very least, your reported HDOP exceeds GPS_HDOP_GOOD. You may still have other issues, but investigate that first.
GPS_HDOP_GOOD is set to 100
Satellite reception is weak, HDOP is high. Appears you are either indoors or next to very tall buildings. Go outside and make sure there’s a clear sky view (maybe the roof of that building, since you’re in the city).
Are you inferring “poor reception” from NSats and the overall error HAcc, VAcc, etc? Or something more specific
All constellations are enabled and only 8-10 satellites received on an M8 - that’s likely poor reception.

Very helpful responses. Thank you all! I didn’t realize that gps_hdop_good was in different units than hdop. I’m not planning on flying in New York City, but I’d like to make sure everything is correctly configured before driving to a more suitable location.
A thought on error messages - it would be incredibly helpful if the messages include the parameter that failed in the comparison.
I’ll try again in Central Park tomorrow.
Thanks again - Mike
