Please add the GNSS receiver position setting on the model

[and-sh]

It is not always convenient to place the GNSS receiver precisely in the center of the drone.
As a result, the drone rotates around the receiver, requiring additional, unnecessary corrections to the drone's position.

This setting has been used in Ardupilot for a long time.

GPS:

GPS1_POS_X, GPS1_POS_Y, GPS1_POS_Z the first GPS’s position from the vehicle’s IMU or center-of-gravity

How big is your aircraft?

In the most recent test by the US Space Force, their lab-grade GPS receivers were accurate to within 7 meters , 95% of the time.

Is your module more than 7 meters from the center of your vehicle?

[and-sh]

Well. This is a position log from my receiver, recorded using Ublox U-Center. The log is 5 minutes long at a rate of 5 points per second, resulting in 1500 points total.

Interesting. I suppose maybe you don't actually need it to be accurate, just stable? In other words, if it's 1 meter off, but remains 1 meter off at the same position, that's okay for some purposes, eh?

I'm trying to picture what exactly it happens if the nose of the aircraft stays in position rather than the center. The aircraft rotates about the nose rather than about the center?

IMHO, unless you're using RTK. This is pretty unnecessary. The size of our models are smaller than the accuracy of the GNSS modules.

ArduPilot does support RTK. Which is why those settings make sense in certain installations.

I’ll make a video when I have the opportunity.
Inav fully supports RTK. I transmit corrections to the receiver via a separate radio modem. I’ve been flying with RTK for over six months and I’m completely satisfied. There are minor inconveniences like displaying HDOP instead of EPH, but they are easy to fix.

p.s.
If you can set up an RTK base station on an NSRS geodetic control point and somehow determine its exact coordinates, the positioning will be highly accurate.
