I’m hoping this is an easy one. I’ve got a PX4 with an M8T on-board and also a Chinese M8N, mostly for the compass. My GPS status is consistently “4”, though I’m not sure what that means. I’m also using the state network for NTRIP.
How can I tell what my accuracy is? Is it GPS HDOP? And if so, is that in decimal meters of accuracy? I’m getting .4 to .5 HDOP numbers, but I have no idea how to tell if that’s raw GPS or what, if any, the NTRIP feed is contributing.
Where can we get a measurement of accuracy on the GPS position?
