Product Overview
General
Information
The GPS 1000 Plus 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 Plus utilizes differential correction
from the WAAS satellite differential system. The GPS 1000 Plus
provides 2-meter accuracy when using WAAS differential and 4 meter
accuracy without any differential correction.
The GPS 1000 Plus is a valuable addition for general data logging such
as soil sample collection, scouting, site verification or as a GPS receiver
for yield mapping.
The GPS 1000 Plus has the ability to output a radar speed signal into
your controller or other equipment that accepts radar speed input.
Adaptor cables are available through Ag Leader Technology for Hiniker,
Raven, and Dickey-John radar guns.
The GPS 1000 Plus is weatherproof and protected against power surges
that are common on agricultural equipment. The GPS 1000 Plus is also
backed by a 2-year warranty.
Wide Area Augmentation System (WAAS) differential correction is an
alternative to subscription based satellite differential correction.
The GPS 1000 Plus requires no initial setup to begin fieldwork. The
PF3000, (Figure 1), YM 2000, (Figure 2), or Insight yield monitor 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.
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.

Installation
Installing the
Antenna on

Installing with antenna magnet:
Installing antenna with L-bracket:
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
• 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.
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.
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.

Radar Speed
Default Settings
The GPS 1000 Plus is capable of outputting a simulated radar speed
pulse. This simulates a similar pulse output that you would receive from
a standard radar gun. The GPS 1000 Plus provides the capability to
provide simulated radar speed to your YM2000, PF3000, PF3000 Pro, PF
Advantage, or Insight display. To use the radar speed input with an Ag
Leader display, you must set the speed input to RADAR under the
appropriate setup screen for the monitor/display. Additional cables will
also be required to obtain the simulated speed output. Contact Ag
Leader’s Technical support team for these additional cables.
Adaptor cables are available through Ag Leader Technology for the
following three radar gun brands Dickey-John, Raven, and Hiniker.
These adaptor cables provide the ability to use the GPS 1000 Plus in
place of a radar gun. If using the GPS 1000 Plus as a stand-alone
antenna, you will need to obtain an Auxiliary Power/Data Cable, GPS
power supply cable listed on page 15, and the appropriate Radar Speed
Adaptor Cable.
The default output parameter provided in the GPS 1000 Plus is a
minimum output speed of .5 MPH, meaning speed pulses will not be
output below this speed. The default radar pulse output rate is 45 Hz per
MPH.
