Collecting Almanacs
Each satellite broadcasts a message (almanac) which gives the approximate
orbit for itself and all other satellites. If the receiver has an almanac, you can
considerably reduce the time needed to search for and lock on to satellite
signals.
The receiver regularly updates the almanac and stores the most recent almanac
in its Non-Volatile Random Access Memory (NVRAM).

Set up the receiver (connect the external antenna if needed) in a location
with a clear view of the sky.
