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.
