How does DJI’s Find My Drone feature work?
DJI’s Find My Drone feature uses a combination of GPS, GLONASS, and BeiDou satellite systems to provide location data for your drone. When your drone is connected to the DJI GO app, it can transmit its location data back to the app in real-time, allowing you to track its whereabouts.
In the event that your drone disconnects from the app, the Find My Drone feature can still provide the drone’s last known location, making it easier to recover. The feature also allows you to set a “home point” which is the location where you first connected your drone to the app, providing an additional reference point to help you locate your drone.
How accurate is the Find My Drone feature?
The accuracy of the Find My Drone feature can vary depending on several factors such as satellite signal strength, environmental conditions, and the quality of your drone’s GPS module. In ideal conditions, the feature can provide location data that is accurate to within a few meters. However, in areas with heavy tree cover, tall buildings, or other sources of interference, the accuracy may be reduced.
In our tests, we found that the Find My Drone feature was generally accurate, but there were instances where the location data was off by up to 10-15 meters. While this may not be a major issue for most users, it could be problematic in situations where precise location data is critical.
Can I use the Find My Drone feature to track my drone in real-time?
Yes, the Find My Drone feature allows you to track your drone in real-time, as long as it is connected to the DJI GO app and has a stable internet connection. This can be useful for monitoring your drone’s flight path, as well as tracking its location in the event that it becomes disconnected.
