Product Overview
General
Information
The GPS 1000 is an all in the antenna DGPS receiver that provides
position data for operations that do not require sub-meter position
accuracy or guidance. The GPS 1000 utilizes differential correction from
the WAAS satellite differential system. The GPS 1000 provides 2-meter
accuracy when using WAAS differential and 4 meter accuracy without
any differential correction.
The GPS 1000 is a valuable addition for general data logging such as soil
sample collection, scouting, site verification or as a second GPS receiver
for yield mapping.
The GPS 1000 is weatherproof and protected against power surges that
are common on agricultural equipment. The GPS 1000 is also backed by
a 2-year warranty.
Wide Area Augmentation System (WAAS) differential correction is an
alternative to subscription based satellite differential correction.
IMPORTANT: WAAS is currently free of charge, and is
being funded by the Federal Aviation Administration (FAA).
WAAS is currently in test mode, and Ag Leader Technology
can not guarantee the availability or quality of its position
signals. Only two (2) WAAS satellites are currently covering
North America.
The GPS 1000 requires no initial setup to begin fieldwork. The PF3000,
(Figure 3) or YM 2000, (Figure 4) will display a "D" or "G" on the top
right hand corner of the display to indicate a GPS signal. A "D"
indicates that a differential signal is being received. A "G" indicates that
you have a GPS signal and your GPS receiver is tracking four or more
satellites (which means you can get an elevation reading). A lower case
"g" indicates that you have a GPS signal but your GPS receiver is
tracking only three satellites which means you can not get an elevation
reading. Your GPS receiver must track four or more satellites to get an
elevation reading.
The unit is defaulted to 4800-baud, 8, N, 1 output. One position is output
per second using GGA and VTG NMEA messages by default.

GPS 1000 Utility
Using GPS 1000
Utility Version 1.0
The GPS1000 is pre-set at the factory to work with an Ag Leader yield
monitor system. Other applications may require special message
settings which can be changed with this utility. Refer to the
documentation for your software application and/or hardware to
determine its required baud rate and NMEA messages.
1. Connect the GPS1000 to a computer using either the Ag Leader
GPS1000 Mobile Logging or GPS1000 Auxiliary Power/Data
cable.
2. Insert the Ag Leader Software Suite CD into the computer CD-
ROM drive.
3. The CD Menu will now appear. Click on "Start GPS 1000 Utility
Program." The GPS 1000 utility program will now start.
4. Click on the "Connect" button below, then select the COM port and
the baud rate for the computer that you are connected to. The
correct baud rate should be 4800 unless you have previously
changed it on the GPS 1000.
5. The Messages tab will now be displayed. Once you have specified
the desired settings, click the "Send Settings" button to send the
changes to the GPS1000.
NOTE: The Messages tab does not display the current
configuration of the GPS1000, only the setting options that are
available and the recommended factory defaults.
6. The Serial Data tab will now appear and the selected NMEA
messages should now be scrolling down the screen as they are
output from the GPS1000. Click pause to stop the message sending
for easier viewing.
7. Click on Exit to finish.

Parts, Tools for
Antenna
Installation
Installing the
Antenna on
Combine or
Tractor
The following parts and tools are needed to install the antenna and its
bracket:
• 5/16 in. self tapping bolts • L-bracket
or 5/16 in. bolts with serrated nuts • Antenna/Receiver
• 1/4 in. drill bit for thin metal • Marker
or 9/32 in. for thicker metal • Punch
• Power/Data Cable ? Hand drill
• Three white cable tie-downs
with self tapping screws
• Three white cable tie-downs
The antenna magnet is very powerful and will stick securely to any metal
surface. If needed, an L-bracket for mounting the antenna is provided.
The L-bracket is used for mounting the antenna (especially on combines)
but not necessary.
Determine a mounting location that is in the center of the swath and the
highest point of the vehicle. Ensure that no part of the machine is
blocking a clear view of the sky to the antenna. Ensure the antenna is
mounted low enough so it won't be knocked off when pulling the vehicle
into the shed. Find a mounting location that if it does get struck it can
slide off.
Installing with antenna magnet:
Step Action
1 Locate a flat metal surface on the vehicle; set the antenna
on it ensuring the magnet adheres securely.
2 Ensure you leave some slack in the cable between the
antenna connection and first tie down. Route cable to cab
using cable tie-downs every 12-18 inches to secure cable.
Installing antenna with L-bracket:
Step Action
1 Place the top surface of the bracket 1/4-in. above the top of
the highest metal surface of the vehicle. This ensures the
antenna is the highest point of the vehicle and can slide off
if struck.

• Check to make sure the cable isn't
damaged and that the connector is
clean and dry.
• Connect the GPS 1000 to a PC
using the Aux. Power/Data cable
and run the GPS 1000 utilities
