POSITION (POS)
When the POS key is pressed the NAV 5000 checks its Almanac to
determine which satellites are scheduled to be in view, and which
of the available satellites will give the best geometry for a position fix. lf
satellites are scheduled to be in view, the receiver turns on and the
display goes to the receiver screen.
Taking a Position Fix
Press POS. The unit checks
its Almanac to determine
which satellites are
available, based on your
last position fix.
lf no satellites are sched-
uled to be in view, the
receiver does not turn on.
lf satellites are scheduled
to be in view, the unit starts
the Instafix
TM satellite
search algorithm. Satellite
receiver activity is moni-
tored on the receiver status
screen.
