1. Heading (z-axis rotation);
2. then pitch (y-axis rotation);
3. then roll (x-axis rotation).
It is important to get the order of the rotations correct.
The AV200 can be mounted at any angle in the vehicle as long as the orientation is described in the
configuration. This allows the outputs to be rotated based on the settings entered to transform the
measurements to the vehicle frame.
Antennas
The AV200 has SMA connectors for the primary and secondary GNSS antennas. Antennas used with
the AV200 must at least be capable of tracking the GPS L1 signal for operation and additionally the
GPS L2 signal for RTK performance. Antennas capable of tracking L1 and L2 GLONASS signals, E1
and E5b Galileo signals, and B1 and B2 Beidou signals should be used for optimal performance and
improved reliability.
When using the AV200 in a dual antenna configuration, it is recommended to use the same type of
antenna with the same cable lengths for both the primary and secondary receivers.
The AV200 is certified for use with GNSS antennas with a gain of <= 35 dB.
Antenna placement and orientation
For optimal performance it is essential for the GNSS antenna(s) to be mounted where they have a clear,
uninterrupted view of the sky and on a suitable ground plane, such as the roof of a vehicle. They should
be mounted away from any potential sources of interference, such as LiDAR systems.
For dual antenna systems, the secondary antenna should be mounted in the same orientation as the
primary antenna, as shown in Figure 9. The antenna baseline should also be aligned with one of the
vehicle axes where possible, either inline or perpendicular to the vehicle’s forward axis.

a) The bases of the antennas are parallel, but the cables exit in different directions.
b) The cables exit in the same direction but the bases of the antennas are not parallel.
c) The bases of the antennas are parallel and the cables exit in the same direction. This configuration
will achieve the best results.
