-===== Autopilot =====

-Three seperate processes:
+Still being planned
-==== Flight/waypoint management ====
-  * Keeping a list of waypoints. Waypoints consist of a position and an optional required altitude.
-  * Calculating "sub waypoints" for circling around to get to required altitudes etc.
-  * Calculating when a waypoint is reached based on GPS position and thresholds (we don't want it turning back on itself if it just misses it!)
-  * Calculating headings to go in based on the current position and the next waypoint (continuous so it will not drift off course)
-==== Roll control ====
+==== Other pages ====
-  * Maintaining straight flight.
+  * [[.software:client]]
-  * Calculate current heading (I believe this is a built in feature of some GPS receivers)
+  * [[.software:protocol]]
-  * Bank and turn based on heading to next waypoint and current heading
-==== Pitch control ====
-  * Maintain constant airspeed, maybe based on stall speed at current altitude or fixed pitch.
-===== Possible ground station =====
-To display:
-  * Readings from sensors.
-  * Flight plan and waypoints
-  * Attitude/artificial horizon
-  * Altitude.
-  * GPS position.
-  * Speed.
-  * Rate of descent/ascent.
-  * Payload status (ascending, descending, landed etc).
-  * Raw output from log.
-  * Battery voltages.
-  * Space remaining on disk.
-  * Number of photos taken and, depending on bandwidth, a compressed version of the last image.
-To send:
-  * Cut down.
-  * Take photo.
-  * Change/add to flight plans.
-  * Edit/add to waypoints.
-  * Manual control for emergencies.
-  * Release parachute.
