Hi Folks, I'm trying to solve the following problem: Given the following: - latitude, longitude of departure - latitude, longitude of arrival - scheduled departure time - scheduled arrival time
I want to calculate the current position of the aircraft , sssuming that it travels along a great circle route between these two points and also assuming that the current time is somewhere between arrival and departure. I currently have two questions: 1). Is there already code available in FlightGear or SimGear that can do this for me? I browsed the waypoint and math directories in SimGear, and the route manager files in FlightGear's Autopilot directory, where I found lot's of code to solve parts of the porblem[*], but I couldn't find a full solution yet. 2). Is it possible to translate the solution from a spherical coordinate system to a WGS84 world model? I have a fairly good concept of how I would solve this problem using a spherical world model, but I don't know yet how I should adapt this to a WGS84 model. I need this function for an AI traffic manager that I'm currently writing for FlightGear. [*] Using existing FlightGear/Simgear code, I managed to calculate the distance between two points, which I could then divide by the difference between Arrival and Departure time, to get the average speed of travel. Thanks in advance! Any hint is welcome. :-) Durk _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
