add "move and rotate waypoints" mavlink command

[tridge]

add a single atomic command to move a set of waypoints with a rotation

[haygood]

So, take a set of waypoints of a given pattern or shape and scoot the whole pattern over and rotate the pattern?

[tridge]

yes. I have that in mavproxy now (I added it for the OBC drop), but it isn't atomic. I'd like it as an atomic command, to prevent packet loss leaving the aircraft with inconsistent mission items (that happened to us in our OBC mission)

[NiqueIt]

Like this too. My case are takeoff and landing procedures. Like to store a pattern and load it when a mission is planned. first, the approach has to moved to the planned launchpoint (and rotate). Just before the mission starts, we take care of the wind and probably neet to rotate the approach again. The approach is a subset of all WPs. Launch will not be complicate as it seems to be only a takeoff-WP. But the landing approach will contain more WPs

A side-effect of doing this with on-board lua via the linked pr is that it's not 'lossy'
from the telemetry stream, and lua can easily read an entire mission (or multiple replaceable missions ) from the SD card. sure, there's tiny issue/s with how to handle the transitional state/s between mission loads, but lua doesn't need to 'wipe' mission/s in between, and it can even know which mission item is actively being executed and avoid over-writing the in-use item till it's no-longer-in-use etc... #13685
