Use these commands to set the type of dynamics the GNSS antenna is subjected to.
The
Level
argument sets the balance between noise and dynamics in the GNSS measure-
ments and the PVT solution. If rapid displacements (such as those caused by shocks, drops,
and oscillations) need to be detected, the
Level
argument can be set to
High
. In that case,
high-frequency motion becomes visible at the expense of an increase in the noise. Con-
versely, if noise reduction is important, the
Level
argument can be set to
Low
. It is generally
recommended to keep the default value (
Moderate
), where the receiver will sense the dy-
namics and adapt itself accordingly. The
Max
level is a special setting, for which the naviga-
tion filter is disabled and the receiver computes epoch-by-epoch independent PVT solutions.
Note that the
Max
level can lead to a longer latency of the PVT output.
The
Motion
argument defines the general characteristics of the receiver motion, such as the
expected speed, rotation, and vibration level. This can help the receiver to optimize certain
parameters for your application.
For example, when selecting the
Pedestrian
motion, signal reacquisition will be faster after
a long outage, as the position is known not to have changed much.
Motion Description
Static
Fixed base and reference stations.
Quasistatic
Low speed, limited area motion typical of surveying applications.
Pedestrian
Low speed (<7m/s) motion. E.g. pedestrians, low-speed land
vehicles, ...
Automotive
Medium speed (<50m/s) motion. E.g. passenger cars, rail vehi-
cles. This setting is generally adequate for most applications.
EarthquakeMon
Specific setting for earthquake monitoring, where the position
is mostly static, but can suddenly change during an earthquake.
Unlimited
Unconstrained motion.
