4. Introduction MoveRTK
• GPS support in agriculture is important:
– Efficiency and Productivity
Necessary because of decreasing prices and increasing costs
– Precision farming and Information management.
Everything on the field is position related:
planting, green mass, fertilization, work tracks, pest management
resources. Parcels are no longer considered as one entity.
– Assistance in complying to environmental protection rules

13. Introduction MoveRTK
• Individual base stations less efficient
• Situation in 2009: Network MoveRTK
13-4-2011 CAPIGI MoveRTK 13

14. Introduction MoveRTK
• Branch organisations prefer standardised RTK correction
signals
– Most GPS-RTK users are using local GPS reference antennas.
– Often brand depended, limited freedom in choice of equipment.
– Many technical and economical disadvantages.
– Branch should stimulate GPS guidance and precision farming
quickly.
• LTO, CUMELA and BN:
– offer members a high quality standardised product for a low
price.
– stimulate use of GPS in agriculture and construction.
– Competition over hardware, not over correction signal

15. Explanation technique:
Network RTK
13-4-2011 CAPIGI MoveRTK 15

16. Explanation technique: Network RTK
• Positioning of one single (“Stand-Alone”) GPS receiver
in a GPS system
• Accuracy GPS 5 – 10 m
– Suitable for navigation (TomTom)
– Not suitable for machine control
• Maximal influence error sources
13-4-2011 CAPIGI MoveRTK 16

17. Explanation technique: Network RTK
• Estimation total influence of error sources on
a known position -> corrections
• Send corrections
to the rover
• Apply corrections
-> reduce influence error sources
• Calculate accurate position

22. Components and functioning
13-4-2011 CAPIGI MoveRTK 22

23. Components and functioning
• Next to the MoveRTK correction signal and the delivered SIM-card,
one needs:
1. GPRS/UMTS modem
to receive MoveRTK
correction signal.
2. GPS/GNSS RTK-
receiver.
The modem (1) is
often incorporated in
the receiver.
3. Wheel control
assistance or
automatic heading
system on the
machine.
4. Display in the cabin
for overview and
programming.
13-4-2011 CAPIGI MoveRTK 23

24. Components and functioning
1. The GPS-receiver in the
machine connects itself to the
MoveRTK control center and
transmits its position.
2. In the MoveRTK control
center, GPS data are
received from a network of
reference stations 24 hours
per day.
All GPS knowledge is
represented in a nation wide
model.
3. Within a split second,
individual corrections are
calculated for the location of
the machine and send by
mobile internet to the
machine. Each second again.
