bool mission_point_of_lla	(	struct EnuCoor_f *	point,
		struct LlaCoor_i *	lla
	)

Utility function: converts lla (int) to local point (float)

Get the ENU component of LLA mission point This function is firmware specific.

TODO: don't convert to float, either use double or do completely in fixed point

Here is the call graph for this function:

int mission_run

(

void

)

Run mission.

This function should be implemented into a dedicated file since navigation functions are different for different firmwares

Currently, this function should be called from the flight plan

Returns

return TRUE when the mission is running, FALSE when it is finished
