NEW HOLLAND PLM –
THE COMPLETE, FLEXIBLE GPS SYSTEM
HOW TO CHOOSE YOUR
GUIDANCE SOLUTION
FOUR LEVELS OF ACCURACY
1. AUTONOMOUS WITH ONPATH FILTER
For Autonomous systems only, utilising mathematical filters to
increase the system accuracy. The OnPath filter provides +/-30-
45cm pass to pass accuracy without the use of a correction
signal.
increase the system accuracy. The OnPath filter provides +/-30-
45cm pass to pass accuracy without the use of a correction
signal.
2. OMNISTAR VBS (SINGLE FREqUENCY CORRECTION)
The vehicle with a DGPS antenna receives signals from the GPS
satellite constellation.
satellite constellation.
The OmniSTAR® services, which have a number of ground based
GPS receivers spread across the area for which they deliver a
correction, receive the same GPS messages as the vehicle. They
are able to calculate the real time position error and send this as
a message to control stations, which then upload the message to
a geostationary satellite. The geostationary satellite receives the
correction message, and re-transmits it as a single frequency
signal back to the receiver on the vehicle.

3. DIFFERENTIAL GPS WITH OMNISTAR®
(DUAL FREqUENCY CORRECTION)
Process as per OmniSTAR VBS.
On this higher accuracy system, the geostationary satellite,
transmits the correction message as a dual frequency signal back
to the receiver on the vehicle.

4. RTK (REAL TIME KINEMATIC)
This is a highly precise technology that results in +/-2.5 cm
year-to-year accuracy.
year-to-year accuracy.
This accuracy can be achieved with two communication
technologies, depending upon your needs in terms of working
area coverage:
technologies, depending upon your needs in terms of working
area coverage:
RTK (RADIO TRANSMISSION)
RTK uses a local ground based station which receives the same position data as the mobile unit. By comparing the
received position to its known actual position, the real time error can be calculated. This error is then transmitted via
short wave radio to the mobile unit.
Radio repeaters can be positioned to fill in any areas of signal loss from the base station. Signal loss could be caused
by rugged terrain or thick vegetation.
