I've read through the SDK documentation for both Windows and Android and found some functions for accessing the state of the current GPS connection and Latitude/longitude information.
I am looking to develop an application that uses 3d photogrammatry to monitor a set area in real time and am worried that built-in localization might not update the model accurately enough.
So I am wondering if there is a way to get the lower-level information like connection strength and specific connected satellites. (to compare to GPS information from the ground for better accuracy.) Is this supported? (maybe in specific drones?) Or is my only option to attatch a GPS device to it that I then access seperately?
I also know that DJI offers a drone with GPS-RTK to give this accuracy but I'm looking at alternative approaches because of the big step up in cost.
Any information / suggestions would be of great help! Thanks.
I am sorry to report but there is no access to the raw data from the GPS sensors. The information you found in the SDK documentation is all that is available.
How accurate are you looking for? Generally the accuracy is pretty close, certainly within 1 foot or so and there is specifications for GPS accuracy in specific drone's manuals.
