[QUOTE="suprPHREAK, post: 22472, member: 1505"] Technically, yes. But without a compass, the drone is blind to which direction it is pointed relative to North. So, if the GPS coordinates indicate a movement to the west, and the drone is physically pointed east, it wont know to fly "forwards" to correct the movement. What ends up happening is the drone starts to hunt....it makes a correction in one direction.....then another....then another....and the result is a big spiral, also known at the "toilet bowl effect". DJI tries to eliminate this concern by ignoring GPS imput, and entering atti mode.If the drone is low enough, VPS should keep it stable (as it does indoors). Just as you said with geocaching. Your handheld GPS probably doesnt have a compass to tell you north. So you walk a bit in one direction....nope. Then a bit more in another....nope. Repeat until you stumble on the cache. You have the advantage of being aware of your surroundings. The drone does not. [/QUOTE]
