Outfitted with a micro 4/3 Hasselblad sensor and a 1/2 inch CMOS camera, the Mavic 3 can record video at resolutions of up to 5.1K/50 fps, and it has a 28x digital zoom that's also pretty impressive. Hovering in the same spot is obviously something you want in a GPS drone, especially when you want to take smoother video without much shaking or movement.The DJI Mavic 3 is the best drone for prosumers and videographers who want the best camera drone without having to purchase a camera and drone separately. This is a good indication the GPS is working well. The return to home point must be as precise as possible, preferable around 1 or 2 meters range from the exact point it took off from. The toilet bowl effect is when a drone flies in circles around its initial holding point and it can be very troublesome because it can hit objects if you don't adjust the direction in time.It will hover in the same spot without much movement The drone return to home is very precise.There are 3 main indications of good GPS quality:
QUADAIR DRONE REVIEW YOUTUBE HOW TO
Quite important, wouldn't you think? How to recognise good GPS in drones If the drone has GPS, it will stay in place, but what if you still won't be able to pick up signal?įor that, there usually is a function of automatic return to home when signal is lost.
Lost signal is a fact of life and something you'll almost inevitably stumble upon if you have a drone. The more expensive drones like the ones from DJI have a way to calculate how much battery they need to return home, but most other cheap drones usually do an automatic return to home at a certain battery percentage, usually under 20%. This is when the battery has low battery life, and it should return to home automatically to avoid crashing somewhere randomly.
There are two very important situations where the Return to home (by GPS) is very important. Avoid Flyaways (Low battery RTH and lost signal) RTH can be used by the press of a button on the controller or is triggered automatically on low battery or loss of signal. However a normal waterproof drone can certainly come with GPS. You could do this yourself just by pressing the left stick towards you… and it would have the same effect, catastrophic if the drone is not facing the right direction.Īnother very different way for a drone to return home is when we're talking about underwater drones since they have a tether cable that can be pulled to get the drone back from the water. This can be useful sometimes, but in my opinion, it's mostly a way to trick people. Some drones retain the original orientation and put the drone in headless mode and try their best to get it back to you. The one key return home feature you see on very cheap drones (the ones without GPS) is actually nothing more than the drone pressing the back button. The farther a quadcopter flies, the more important RTH is, so I recommend you check my article on the Best Long Range drones if you want to have the best of both worlds. This usually happens at a set height or at the height you currently are, but we'll see that some drones have additional settings that change a few things. The drone saves a point location at the place you took off from and when the return to home gets activated, it will go in a straight line towards the original point.
The GPS Return to home can also be useful in case you're fishing with your drone and want to get it back to shore. Usually, drone GPS autopilot also has other features like waypoints and circle around, but more advanced flight modes like these are usually found in more expensive drones like DJI ones. This means the drone HAS to have a GPS module and at least a few satellites connected. This is what we're mostly going to focus on, as this is the “true” technology that you can actually use in real-life situations. There are actually two main types of return to home when I think about it:
