RTK Base Station Setup
OUO6050,0002277 –19–27NOV06–3/6
PC8745 –UN–01SEP05
A—Receiver
Picture on the Left: The base station, with receiver
attached 1 foot off the top of the tower, was being
affected by multipath from the dome of the water
tower. The vehicle receiver running off this base
station experienced different symptoms:
• Two vehicles would be operating at the same time.
One vehicle would go from RTK into RTK-X and see
a line jump of up to 6 inches for a couple of minutes,
while the other vehicle would be operating without
incident.
• At a later time, the situation would reverse, and the
vehicle without incident earlier would go into RTK-X
and experience a line jump, while the other vehicle
wouldn’t.
The reason the vehicles behaved differently was
because each vehicle may have been using a different
set of satellites at a given time due to shading and
vehicle location.
Picture on the Right: Base station was elevated 5 feet
off the top of the tower. Raising the receiver greatly
reduced the multipath effects observed on this RTK
system.
