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.

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.

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.
