Auto Satellite Search
To lock on to the satellites, the GPS receiver needs to know its current
position, UTC time and date. Altitude is also used in the equation, but
it's rarely required to determine a position. It needs this data so it can
calculate which satellites should be in view. It then searches for only
those satellites.
When your GPS receiver is turned on for the first time, it doesn't know
what your position or altitude is. It knows the current UTC time and date
since these were programmed into it at the factory and an internal clock
keeps the time while the unit is turned off. If the time and/or date are in-
correct, you can set them using the Set Local Time menu. The unit begins
searching for the satellites using the above data that it acquired the
last time it was turned on. This probably was at the factory. Since it's
almost certain that you're not at our factory, it's probably looking for
the wrong satellites.
If it doesn't find the satellites it's looking for after approximately one
minute, it switches to Auto Search. The receiver looks for any satellite
in the sky. Due to advanced technology, the auto search time has
shrunk significantly from the early days of GPS. Once the unit locks on
to the satellites, it should take less than a minute to find your position the
next time it's turned on, as long as you are approximately 100 miles from
the last location it was used.
