The introduction of the (WAAS) Wide Area Augmentation System
differential correction signal by the (FAA) Federal Aviation
Administration provides improved air traffic control and gives
New Holland customers the opportunity to consider additional
corrections sources with their add-on GPS 3000/3050/3100 GPS
receivers.
What is the advantage of
using the WAAS signal?
The primary advantage of the WAAS signal is that the signal
itself is currently free (although upgrading the add-on GPS
3000/3050/3100 GPS receivers prior to 2002 models will require
an upgrade fee). Customers who are not in range of a strong
Coast Guard beacon signal may be able to utilize the WAAS signal
to obtain an improved signal over using the GPS signal alone.
Who can pick up the WAAS
signal?
The signal is expected to cover most of North America with
the best signal over the United States and southern Canada.
The system occasionally does get turned off for system changes
and updates, but is still a consideration for customers who
are not in range of the U.S. Coast Guard beacon signal. The
WAAS signal will not be as accurate as L-band satellite differential
correction, but will be better than a GPS signal without differential
correction.

Do I need
to do anything with the PLMS yield monitor prior to using
WAAS?
If you have version 3.21 in the PLMS yield monitor
it will need to be upgraded to version 3.22. Version 3.22
can be downloaded from the New Holland Internet site listed
below:

Once version 3.22 is loaded onto the PLMS yield
monitor it will be necessary to take the entire PLMS yield
monitor and add-on GPS 3000/3050/3100 GPS receiver to your
New Holland dealer to complete the upgrade.
Where can
I find additional information on how the WAAS signal works?
