问题
I am currently trying to implement a waypoint using DJI's mobile SDK.
However, it is difficult to obtain the position of the drones when connected without simulation.
What should I do?
回答1:
Are you outdoors with a good GPS signal?
回答2:
It is difficult to determine your real question but if the aircraft has a clear view of the sky then it will attach to a number of GPS satellites and report location through the call as shown below. If you don't have a clear view to the sky (technically southern exposure) then the GPS will not be able to establish a connection to the GPS satellites and will not report location. Unlike your cellphone (which can use GPS, cell site and WIFI to locate itself) the aircrafts only have GPS.
Application.getAircraftInstance().getFlightController().setStateCallback(new FlightControllerState.Callback() {
@Override
public void onUpdate(FlightControllerState djiFlightControllerCurrentState) {
}
});
