built-in settings for the RTK rover, the RTG dynamic, and velocity smoothing. No
additional parameters are needed. When a user specifies dynamic mode as USER,
additional parameters can be added to configure the RTK rover, the RTG dynamic,
and the velocity smoothing settings.
It is assumed that the receiver is navigating at a rate of 1 Hz. As a rule of thumb,
the higher the rate at which the receiver navigates, the higher the dynamics the
settings can accommodate.
