A Bit About ISOBUS and TeeJet® Technologies
• In 2001, farm machinery manufacturers agreed to implement a common standard for communication interfaces on tractors,
implements and farm management systems. The standard is called ISO 11783 and is commonly referred to as ISOBUS.
The common standard enables products from different manufacturers to communicate and eliminates the need for separate
terminals, displays and controls. Once ISOBUS is fully implemented, tractors will have a single virtual terminal in the cab
• A virtual terminal is the device that allows the operator to provide input information. An Electronic Control Unit (ECU),
also known as a job computer, is installed on the implement and is where processing and control occurs
• TeeJet Technologies has been a global leader in ISOBUS development and implementation. Design and manufacturing of ISOBUS
components for sprayers and spreaders started in 2001

GPS Accuracy Definitions
Pass-to-pass accuracy measures the relative accuracy of a GPS
receiver over a 15-minute interval. It does not reflect the long-term
accuracy, which is affected by GPS drift.
Year-to-year repeatability is the measure of repeatable
accuracy that allows one to return to the same point and follow
the same guidance path a day, week, month or year after being
initially established.
Different System Accuracies:
+/- 1 in/2 cm
(also referred to as
centimeter or sub-inch)
+/- 1 in/2 cm
+/- 2-4 in/5-10 cm
(also referred to
as decimeter)
+/- 4 in/10 cm
+/- 3-5 in/8-13 cm
(also referred to
as decimeter)
+/- 8 in/20 cm
VBS, Beacon,
+/- 6-10 in/15-25 cm
(also referred to
as sub-meter)
+/- 3 ft/1 m
GPS Glossary
A device for transmitting and receiving radio frequency (RF) signals.
In terms of guidance devices, a GPS/GNSS antenna merely accepts
signals from satellites or base stations. No internal calculations are
performed within the antenna.
Base Station:
A stationary GPS/GNSS receiver that serves as a reference point,
providing correction data to a “rover” GPS/GNSS unit. Correction
data can be broadcast via RF, cellular signal or the Internet.
Commercial Satellite Provider:
Another common source for DGPS signals. Error correction
information obtained from their base stations is sent to a
communications satellite (separate from the GPS satellites)
and broadcast to the user. These satellite-based corrections
tend to have more widespread coverage than tower-based
broadcasts (FM links), and system accuracy is not greatly
affected by the user’s distance from the base station receivers.
Most of these service providers require a subscription fee for
use. A commonly known provider is OmniSTAR®.
GPS Glossary
CORS (Continuously Operating Reference Station)/
Network RTK:
A series of base stations spread across a given geographic
region (such as an entire state/county) that are networked via
a centralized computer and which broadcast RTK correction data
over the Internet. CORS networks may be publicly or privately
owned/operated and may offer a free signal or require an annual
subscription fee. By accessing a CORS network via a cellular
connection, the end-user eliminates the need to own a base station.
GPS Drift:
Positional shift that can be caused by changes in satellite
constellation, operating near trees or other obstacles and satellite
clock errors. RTK correction is recommended for field applications
where the effects of GPS drift need to be minimized.
GPS Receiver:
Converts the satellites’ signals received via antenna into
position, velocity and time. This information is used for navigation,
positioning, time dissemination and research.
Differential GPS (DGPS):
The most common way to correct for normally occurring GPS errors.
Examples of DGPS include WAAS, EGNOS, OmniSTAR® and RTK.
Dual Frequency or L1/L2:
This term refers to a navigational receiver capable of using
L1 and L2C satellite frequencies to derive a position.
EGNOS (European Geostationary Navigation
Overlay Service):
A satellite based augmentation system (SBAS) developed jointly
by the European Space Agency (ESA), European Community and
EUROCONTROL. The system is free to use and provides differential
correction coverage primarily across the European continent. EGNOS
delivers pass-to-pass accuracies of 6-10 in/15-25 cm and year-to-year
accuracies of 3 ft /+/-1 m.
GLONASS (Global Navigation Satellite System):
A global satellite navigation system developed and operated by the
Russian government. It is composed of approximately 24 satellites
which continuously orbit the earth. While early GNSS receivers
typically utilized only GPS signals, many of today’s GNSS receivers
can utilize signals from both GPS and GLONASS, effectively
increasing the total number of satellites available for use.
GPS (Global Positioning System):
The name of the satellite-navigation network maintained by the
U.S. Department of Defense. It is composed of approximately
30 satellites which continuously orbit the earth. The term is also
used to refer to any device that depends on navigation satellites
for functionality.
GNSS (Global Navigation Satellite System):
A general term that refers to a multiple satellite navigation
system used by a receiver to compute its position. Examples of
these systems include: GPS developed by the United States and
GLONASS by Russia. Additional systems in development include
Galileo by the European Union and Compass by China. New
generation GNSS receivers are being designed to utilize multiple
GNSS signals (such as GPS and GLONASS). Depending on
constellation and desired accuracy levels, system performance
may be improved by having access to a greater number of satellites.
RTK (Real Time Kinematic):
Currently the most accurate GPS correction system available
that uses a land-based reference station located in relatively
close proximity to the GPS receiver. RTK can provide one-inch,
also known as centimeter, pass-to-pass accuracy and also provides
year-to-year position stability. RTK users can have their own base
stations, subscribe to RTK Networks or use CORS.
SBAS (Satellite Based Augmentation System):
A general term that refers to any satellite-based differential
correction system. Examples of SBAS include: WAAS in the
United States, EGNOS in Europe and MSAS in Japan.
Additional SBAS covering other regions of the world will
likely be coming online in the future.
WAAS (Wide-Area Augmentation System):
A satellite correction service developed by the Federal Aviation
Administration (FAA). It is free to use and provides coverage
across the U.S. along with parts of Canada and Mexico.
WAAS delivers pass-to-pass accuracies of 6-10 in/15-25 cm;
however, year-to-year accuracy will be in the range of +/- 3 ft /1 m.
