Getting Satellite Signals
After you turn on the GPSMAP 376C, the unit automatically begins
searching for satellites. The GPS page appears while the unit is
gathering satellite signals and acquiring a x, which should take
only a few minutes. While the GPSMAP 376C is getting satellite
signals, the GPS page shows the status as “Acquiring Satellites”.
GPS Tab
NOTE: While acquiring satellites, the Map Page might show
the wrong location, such as China. You need to wait a few more
minutes to acquire satellites and nd your current location.
Viewing GPS Status
The GPS tab provides a visual reference of satellite acquisition,
receiver status, and accuracy. The sky view and signal strength bars
show what satellites are visible to the receiver and whether they are
being tracked.
As the receiver locks onto satellites, a signal strength bar appears
for each satellite in view, with the appropriate satellite number
underneath each bar. The numbers below each bar represent the
particular satellite that is being received. Numbers above 33 indicate
WAAS satellites.
The sky view shows a bird’s eye view of the position of each
satellite relative to the receiver’s last known position. The outer
circle represents the horizon (north up), the inner circle represents
45º above the horizon, and the center point represents a position
directly overhead. You can also set the sky view to a Track Up
conguration, causing the top of the sky view to align along your
current track heading. Press MENU to change the conguration of
the sky view.

The progress of satellite acquisition is shown in three stages:
• No signal strength bars—the receiver is looking for the
satellites indicated.
• White signal strength bars—the receiver has found the
satellite and is collecting data.
• Green signal strength bars—the receiver has collected the
necessary data from this satellite.
When the GPSMAP 376C collects the necessary data from the best
satellites in view to calculate a x, the status eld indicates the
status of the receiver. The unit updates the location, date, and time.
Receiver Status
The Receiver Status eld shows one of the following conditions:
• Searching the Sky—the receiver is looking for satellites.
• AutoLocate—the receiver is looking for any satellite whose
almanac was collected, which can take up to ve minutes.
• Acquiring Satellites—the receiver is looking for and
collecting data from satellites visible at its last known or
initialized location but has not acquired a x.
• 2D GPS Location—At least three satellites were acquired
and a two-dimensional position x was calculated.
“2D Differential” appears when you are receiving DGPS
corrections in 2D mode, and a “D” appears on the strength bar
of satellites being corrected.
• 3D GPS Location—At least four satellites were acquired
and a three-dimensional x was calculated. “3D Differential”
appears when you are receiving DGPS corrections in
3D mode, and a “D” appears on the strength bar of satellites
being corrected.
• Lost Satellite Reception—the receiver is no longer tracking
enough satellites for a 2D or 3D x.
• Receiver Not Usable—the receiver is unusable, possibly due
to interference or abnormal satellite conditions. Turn the unit
off and back on to reset it.
•Simulating GPS—the receiver is in Simulator Mode.
• GPS Off—the GPS receiver is turned off.

GPS Tips
While the receiver is gathering information, your location on the
map might appear different from where you actually are located.
As soon as the receiver gathers enough satellite information, your
proper location appears on the map.
Any time you have traveled more than 600 miles with the GPS
receiver turned off, the receiver might take longer than normal to
initialize and nd your location.
The GPS receiver can lose satellite signals due to interference from
such items as buildings, tunnels, and heavy tree cover. Monitoring
the GPS status is recommended.
