GPS 152H Owner’s Manual
Using the Celestial Tab
The Celestial tab shows information about sunrise, sunset, moonrise,
moonset, the moon phase, and the approximate sky view location of
the sun and moon. By default, the unit shows celestial information
for the present date and time.
From any Main page, press Menu twice and highlight Celes.
To select a date and time for which to view celestial information,
select the date or time field and enter text as described on
page 2.
If your orientation is set to North Up and you want to quickly
switch to Track Up while viewing the Celestial screen, press
Menu and select Track Up.
Using the GPS Tab
The GPS tab displays GPS satellite positions and signal strength
bars.
From any Main page, press Menu twice and highlight GPS.
Receiver status is indicated by the bar across the top of the screen.
• Looking For Satellites
• AutoLocate®—The receiver does not know your previous
location. This process can take up to five minutes.
GPS 152H Owner’s Manual
Settings
• Acquiring Satellites—The receiver is looking for, and
collecting, data from satellites visible at the last known or
initialized position, but has not collected enough data to calculate
a fix.
• 2D Navigation—At least three satellites with good geometry
have been acquired and a two-dimensional position fix (latitude
and longitude) is being calculated.
• 3D Navigation—At least four satellites with good geometry
have been acquired and your position is now being calculated in
latitude, longitude and altitude.
• Poor Satellite Reception—The receiver is no longer tracking
enough satellites for a 2D or 3D fix.
• Receiver Not Usable—The receiver is unusable, possibly due
to interference or abnormal satellite conditions. Turn the unit off
and back on to reset.
• Simulating Navigation—The receiver is in simulator mode
(page 23).
GPS accuracy information is indicated along the bottom of the
screen.
• Accuracy—indicates the approximate accuracy of the unit.
• DGPS Rcvr—indicates the status of the DGPS receiver
(page 16).
17
Settings
• DOP (Dilution of Precision)—displays DOP, which is an
indication of satellite geometry quality measured on a scale of
one to ten. Lower numbers indicate higher quality signals.
• DGPS SNR—displays the SNR when the unit is receiving a
DGPS signal. The SNR range is 0dB to 30dB, with 30dB being
the best.
WAAS (Wide Area Augmentation System) can provide moreaccurate GPS position information in North America. However,
when using WAAS, the device takes longer to acquire satellites.
To disable WAAS:
1. From any Main page, press Menu twice and highlight GPS.
2. Press Menu, and select Disable WAAS.
You can manually enter your altitude when in 2D navigation
or simulator mode. Any altitude entered will be automatically
calculated when the unit is in 3D navigation mode.
To set 2D altitude:
1. From any Main page, press Menu twice and highlight GPS.
2. Press Menu, and select 2D Altitude.
Using the Tide Tab
From any Main page, press Menu twice and highlight Tide.
The Tide tab shows a chart that displays tide station information
in a 24 hour span, starting at midnight station time. You can select
different dates.
When your unit is turned on, it starts the search for your location
based on where you were when it was turned off. AutoLocate is used
by the GPS 152H to find your location when the unit does not know
your previous location.
To use AutoLocate to find your location:
1. From any Main page, press Menu twice and highlight GPS.
2. Press Menu, and select AutoLocate.
18
GPS 152H Owner’s Manual
The top of the screen displays the tide station. The top of the chart
shows a 24-hour block of local time (LCL) for your position, with
the reported station time (STA) appearing at the bottom. The solid,
light vertical lines are in 4-hour increments, and the light, dotted
vertical lines are in 1-hour increments. A dark, vertical line indicates
the current time.
Settings
To select the tide station nearest your location:
1. From any Main page, press Menu twice and highlight Tide.
2. Press Menu, and select Nearest Tide Station. The name of the
nearest tide station appears along the top of the screen.
Note: You must be within 100 nautical miles of a tide station to
use this feature.

The four data fields below the chart indicate event times and levels
at which the tide changes.
To view tide information for a different date:
1. From any Main page, press Menu twice and highlight Tide.
2. Press Menu, and select Modify Station Opt.
3. Select the Date field and enter text as described on page 2.

Using Simulator Mode
 WARNING
Do not try to navigate using simulator mode because the GPS
receiver is turned off. Any satellite signal strength bars shown are
simulations and do not represent the strength of actual satellite
signals.
Simulator mode turns the GPS receiver off for use indoors or for
practice using the chartplotter. The chartplotter does not track
satellites in simulator mode.

Appendix
The GPS 152H also includes support for the WPL sentence and
sonar NMEA 0183 input with support for the DPT (depth) or DBT,
MTW (water temp), and VHW (water temp, speed, and heading)
sentences.
If you are connected to COM2 for sonar NMEA input, the unit
interface must be set to GARMIN DGPS, Other DGPS (4800
only), or NMEA In/NMEA Out. If connecting to COM1, the unit
must be set to NMEA In/NMEA Out (see page 15).
Caring for the Unit
The case is constructed of high-quality materials and does not
require user maintenance, except cleaning.
Cleaning the Case
Clean the unit’s outer casing (except for the screen) using a cloth
dampened with a mild detergent solution, and then wipe dry. Avoid
chemical cleaners and solvents that may damage plastic components.
24
Cleaning the Screen
The lens on the screen is coated with a special anti-reflective coating
that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners
containing ammonia, alcohol, abrasives, or anti-grease detergents
will harm the anti-reflective coating. It is important to clean the lens
using an eyeglass lens cleaner (that is specified as safe for antireflective coatings) and a clean, lint-free cloth.
