"The RC gets its location feed from the device its plugged into. And that can sometimes be wildly inaccurate."
Would the simplest solution not be to disable GPS/GLONASS on your display device if it's unreliable, unless you want to set home point to RC location or use 'Follow Me' then it is not required at all.
The simplest solution is prior to take off that everything is OK - the home point is correct, the RC distance is correct, distance from HP is correct and orientation regards to the map is correct surely?
I've seen the drone GPS set itself with a fairly inaccurate HDOP on the GPS meaning 30m+ or so error before now. I've also seen magnetic interference that wasn't warned about causing the drone to think it was pointed 45 degrees from where it actually was.
Checks need to pick this up before launching.
Distance to RC comes in useful if you aren't standing in one place and want the drone to land near to where you end up not where it left (especially if the RC is moving at speed like on a boat).
