Using Return to Home

in Drone2 years ago

Using Return to Home (RTH) on a DJI drone is a valuable thing to learn and configure.

Can you tell the difference between this picture, and the one below?

The first picture was just before take-off. The second picture 15 minutes later after I initiated a RTH and auto-landing from a mile away. This was after doing pictures and a video run up the creek a half mile away to spot.

Check my post in the #outdoorsandmore community earlier this week for the full pics and video flyover of the Beaver Dams (see here for that post).

The software was able to raise the drone to my preset defined RTH altitude (380 feet just to avoid trees, powerlines and such), then automatically fly it back home in a straight line to be most battery efficient, then land it right back where it took off from. Ok, maybe it's an inch further back, but I'll take it!

For this session, we started with a picture of the driveway after clearing the morning snow. This is what it means to "Shovel your driveway" in rural Vermont.

If you're new to DJI drones (not sure about other models), this is something you want to configure early. First, check your default settings and change them to either RTH to the start location (or to the controller). Having the RTH set to your controller is better when on a moving boat for example, you don't want it to go back to where you started that may now be open water!

You can then set the RTH height, (I usually set to near the max to avoid trees, powerlines, buildings, etc.) The sensors are supposed to still work in avoidance mode during RTH and fly around objects, but why risk it when you can just go up?

You then have to set what you want it to do if it loses signal. RTH or Land. I always choose RTH. I don't want it to land or even attempt to land away from me.

You can always interrupt the RTH for example, if you lost signal due to range or blockage, you can just stop the RTH when it gets back into range and strong signal. I'll often hit the RTH button when I'm done with a session just so I don't have to manually fly it back, then when it gets back within close range to land, I'll take over and land myself.

You got much better results with RTH than I ever did the Mini 2 was around + or - 2m

Wow, my previous Mavic 1 and Mavic 2 were also like this. I find it is more accurate by ensuring a good satellites locked in (although the Mavic 3 painfully slow to sync) before takeoff and then also using the auto-takeoff, then letting it hover a few seconds there before the rest. If you're already doing that, then not sure why yours would be so far off. All of mine have always been within a few inches at most.
