05 Dynamic Modes - VBOX 3iS Dual Antenna RTK

VBOX 3iS units have three dynamic modes. These dynamic modes directly change the SMI smoothing index applied by the GNSS engine to all Doppler-derived data, most notably speed and heading. The lower smoothing levels have a higher dynamic response but are adversely noisier.

The three options are:

  • High dynamics (default): Should be used for high accuracy trigger brake stops or any test where time and distance are critical and the vehicle test incorporates highly dynamic manoeuvres.
  • Medium dynamics: Suitable for any testing that does not involve any high dynamic manoeuvres.
  • Low dynamics: Can be used for less dynamic applications, such as steady-state speed measurement or coast-down testing.


You can change the dynamic mode via the VBOX Setup Software, the Front Panel of the unit, or with VBOX Manager.
