Satellite longitudes are presented in degree/decimal degree (79.0 W) format since that is the standard
representation of satellite positions. Latitude and longitude of the mount are presented in degree/decimal
(38.9554N, 94.7543W) format.
When referring to an RC4080 mode of operation, that mode's name will be capitalized – ex. LOCATE.
Throughout the RC4080 manual and software, the latitude, longitude and true heading of the antenna are
collectively referred to as the antenna's "position".
Movements of the antenna (as seen from behind the antenna, looking at the arc of satellites) are
represented by graphing the azimuth and elevation axes as shown below.
