Are the way point placements really exact? I made a way point in my back yard, near my patio as the starting point. But when the drone went to the starting point, it was located more to the right than the placement I used on google earth. Am I expecting too much precision? Can I adjust a way point on the RC2 Pro after it has been created on litchihub and expect the drone to follow the new placement? On the RC2 Pro, do I have to re-save the flight path or can I just hit GO and start the mission?
How to change cameras on the Mavic 4 Pro using LitchiHub. I noticed when selecting telephoto on litchihub, when I look at mission on the RC2 Pro, it doesn’t have telephoto selected as the camera. I am not really understand the Camera Zoom action on litchihub either.
I started a mission, the drone took the proper altitude for the first way point and completed the mission. I restarted that same mission with a different camera selected, I selected the camera change on the RC2 Pro, but this time when the drone went to the first way point, it started at a much lower altitude. The first mission was 9 feet, the second mission the drone started at about 4 feet.
They are as accurate as consumer GPS. You may experience fluctuations of up to a few meters or even more in extreme circumstances.
Perhaps.
Yes, you can do that and get the drone to be “exactly” where you want it to be at that moment. However, even if you save the new coordinates of that waypoint, the following day it may appear to be off again.
You can just press “Go”. However, if you want to save that new coordinate so that you can fly it later, you would have to save any changes to the mission.
The height can vary from one mission to the next but your example seems extreme. The drone’s height is determined from atmospheric pressure compared to that when the drone was powered on. This is normally reasonably accurate, however, it can drift. After your first mission, notice the height displayed in DJI Fly just before you land (at the same location where you took off). It should be close to zero. If it is not, it means the atmospheric pressure has changed during your flight. Once you land, the drone’s height will reset to zero. Therefore, it is best to land between flying another waypoint mission to ensure the drone’s height is zeroed before each flight.
It was very cold today, 15 degrees, also turned the drone on inside the house. Snow covered ground.
Also, when saving a dummy way point mission on the RC2 Pro, when I say dummy mission, I mean a mission that will be over written by litchihubs mission. When creating that dummy mission on the RC2 Pro, do I have to save and exit/close the app completely or just save and exit?
Also the camera selection. If you want to use a different camera on the mavic 4 pro, how do change the camera on litchihub? Is it as simple as selecting telephoto in the tab menu that appears on the left hand side of the screen? Or is that just for visual purposes when doing virtual fly through?
The camera lens selector currently is only used for mapping/camera projection calculations in the Litchi Hub. In the app before the flight you should still manually switch to the camera lens you wish to use.
If I don’t like the original way point location when I see the drone actually fly the mission. How do I go about changing that original way point location? I know I can fly the drone to where I want it to be and press c1. But how would I replace, let’s say, the 1st waypoint in a 10 waypoint mission, with the one I just created? Please keep in mind, I am editing a waypoint mission on the rc2 pro, rhat was created on litchihub.
After doing some testing, the drone lands in pretty much the exact same spot it took off. It has to be using the same GPS for way points right?. I believe the conflict is coming from the point of interest, don’t know for sure yet. But removing the POI resolved the problem. It’s important for me to understand this nuance because the shots I want to achieve need to have the subjects center framed on a designated spot.
Also, the drone changing altitudes on repeat missions seems to be something with the snow and bright sun, when close to the ground. I repeated the same mission at dusk with no issues on altitudes changing.
Your drone, the Mavic 4 Pro, uses GPS to get close to the take-off location then uses the vision system to perform precision landing to accurately land.
The existence of POIs should not have any effect on the accuracy of flying a waypoint mission.
Flight altitude is determined by barometric pressure alone. If the sun affected anything, it would be the obstacle avoidance system. You might want to try turning that off and fly the mission during the day.
