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.
