**Hint: When you have a fix position of the aircraft or you know the
location of your receiver, it is convinent to use `position_with_ref()` method
to decode with only one position message (either odd or even)**
**Hint: When you have a fix position of the aircraft, it is convenient to
use `position_with_ref()` method to decode with only one position message
(either odd or even). This works with both airborne and surface position
messages. But the reference position shall be with in 180NM (airborne)
or 45NM (surface) of the true position.**
