2. u-blox NEO-M8P
3. a reference system

Comparing RTK performanceWalk test in an easy environment
The accuracy of the
receivers is so good that
we cannot see any
differences on the map.
All three lines are on top
of each other throughout
the test.
“Truth” – green line
ZED-F9P – blue line
NEO-M8P – purple line

Comparing RTK performanceWalk test in an easy environment
The receivers perform very well and statistics do not show many differences.
In an open environment – single-band NEO-M8P is a good choice
The tests were done with a local base station, and a relatively short baseline (<1 km). A survey grade antenna was used. When using a patch
antenna, the ZED-F9P performance stays the same, while the NEO-M8P performance suffers slightly.

Comparing RTK performanceRoad test in city, 20 km baseline
Road test in Tampere,
urban environment:
1. ZED-F9P
2. NEO-M8P
…and “Truth system”
The environment is an urban
environment, albeit relatively easy.

Comparing RTK performanceRoad test in city, 20 km baseline
Looking at altitude
accuracy, we can see that
the drops in accuracy, due
to signal blockage, for
ZED-F9P are small in
magnitude and relatively
short-lived.
When ZED-F9P drops to
float mode it quickly re-
converges to highest
accuracy.

Comparing RTK performanceRoad test in city, 20 km baseline
Position accuracy of ZED-F9P in the urban environment is excellent!
Multi-band RTK out-performs single-band RTK in a challenging environment.
Tests performed with the ANN-MB multi-band patch antenna.
