Understanding GPS The Global Positioning System (GPS) consists of 24 satellites that circle the earth twice a day in a very precise orbit and transmit information to Earth. The Rino 120 must continuously "see" at least three of these satellites to calculate your location and track your movement. If some of the satellites in view get blocked or "shaded," the receiver simply uses an alternate satellite to maintain the location fix. Because the Rino 120 relies on satellite signals to provide you with navigation guidance, the receiver needs to have an unobstructed, clear view of the sky for best performance. In a nutshell, the GPS receiver's view of the sky generally determines how fast you get a location fix or if you get a fix at all. GPS signals are relatively weak and do not travel through rocks, buildings, people, or metal: So, remember to keep a clear view of the sky at all times for best performance. GETTING STARTED > UNDERSTANDING GPS Your Rino 120 needs to be given the opportunity to find or AutoLocate itself: This is also called initializing the receiver or unit. Longer initialization (AutoLocate) is only necessary: • The first time you use your Rino 120 (new from the factory). • After the receiver has been moved over 500 miles with the power off from the last time you used it. Once you initialize the unit to a location, it typically computes a fix within a couple minutes. Visit the Garmin Web site at www.garmin.com for more information on GPS. Rino® 120 Owner's Manual 7

Understanding GPS
The Global Positioning System (GPS) consists of 24
satellites that circle the earth twice a day in a very precise
orbit and transmit information to Earth. The Rino 120
must continuously “see” at least three of these satellites
to calculate your location and track your movement. If
some of the satellites in view get blocked or “shaded,” the
receiver simply uses an alternate satellite to maintain the
location fix.
Because the Rino 120 relies on satellite signals to provide
you with navigation guidance, the receiver needs to
have an unobstructed, clear view of the sky for best
performance. In a nutshell, the GPS receiver’s view of the
sky generally determines how fast you get a location fix
or if you get a fix at all. GPS signals are relatively weak
and do not travel through rocks, buildings, people, or
metal: So, remember to keep a clear view of the sky at all
times for best performance.
Your Rino 120 needs to be given the opportunity to find
or AutoLocate itself: This is also called initializing the
receiver or unit.
Longer initialization (AutoLocate) is only necessary:
•
The first time you use your Rino 120 (new from the
factory).
•
After the receiver has been moved over 500 miles
with the power off from the last time you used it.
Once you initialize the unit to a location, it typically
computes a fix within a couple minutes.
