Note: Although this uses APM:Copter as the main example the primary methods apply for
APM:Plane and APM:Rover although altitude control is severely limited in APM:Rover.
It is very important to acquire GPS lock before arming in order for RTL, Loiter, Auto or
any GPS dependent mode to work properly.
1.1.1 Basic waypoint commands
A mission file is a little intimidating to the human eye, but is a powerful scripting language for
the autopilot. (Again, remember that the GCS will soon take care of all of this for you. You
shouldn‟t have to see it yourself for long!).
You can have as many commands as you want, ranging from pre-programmed ones to ones that
you can create. Here are some common ones:
{NAV_WAYPOINT n/a, alt, lat, lon}
{NAV_TAKEOFF pitch, target altitude}
{NAV_LAND n/a, alt, lat, lon}
{DO_JUMP waypoint, n/a, repeat count, n/a} Goes to that waypoint and resumes mission there.
Set repeat count to any number greater than 1 to do it that many times. or to -1 to do it forever.
Good for looping missions.
(
Note: DO_xxx commands currently need a dummy waypoint placed after the command
eg:
WAYPOINT_1
DO_SET_HOME
WAYPOINT_2
Home will be set at WAYPOINT_1 but will not work if WAYPOINT_2 is not there.)

1.1.2. Tips
Prefetch: You can cache map data so you don’t need Internet access at the field. Click the
Prefetch button, and hold down Alt to draw a box to download the selected imagery of a
location.
Grid: This allows you to draw a polygon (right click) and automatically create waypoints over the
selected area. Note that it does not do “island detection”, which means if you have a big
