Seed Position
Each time the Apollo GX is switched on, it must locate
satellites in the sky to acquire signals before determining
a position fix in a complex process involving lengthy
mathematical operations. Without a seed position and
the current UTC time and date, this process can take 10
minutes or more to complete. Enter a Seed Position to
allow the receiver to quickly locate and track available
satellites.
Note
The seed position and current time only
need to be entered the first time the receiver
is switched on. This information is stored in
memory and need not be entered again. If
you move about three hundred miles
without the Apollo GX turned on and
tracking its position, reenter the seed
position.

starting reference point so the GPS receiver knows
what satellites to look for. If a Seed Position has been
previously entered, you do not need to select a new
Present Position or a Reference Waypoint. If you do
