The method allows directly specifying the attitude of the vehicle with respect to the relative wind velocity vector and local horizon
, which makes it very suitable for trajectory computations even with a limited aerodynamic database available.
The known altitudes and azimuths of the stars allowed us to accurately map the local horizon
You can also determine planetary positions for any given time interval while the body is above your local horizon
Among his computations are their paths relative to the local horizon
, sunrise/sunset times, lunar phases, and the analemma.
A brilliant flash occurred after the object dipped below the local horizon
Moore's challenge to view all the objects that rise 5 [degrees] above one's local horizon
makes Caldwell-hunting a global game.
