This top-of-the-range data logger combines all the advantages of a twin antenna GPS setup with GLONASS satellite tracking and can be used in any number of vehicle tests where positional accuracy and repeatability are of the utmost importance.
2 cm Positional Accuracy
For tests where positional accuracy is of key importance, like lane departure testing, distance to a fixed object, or precise mapping, the VBOX 3i RTK offers industry-leading 2 cm positional accuracy, in real time, at 100 Hz!
VBOX 3i RTK is the key data acquisition unit of the RACELOGIC ADAS Test Systems for measuring vehicle separation, time to collision, position within a lane, and more to 2 cm precision.
Slip and Pitch/Roll measurement using two antennas
Utilising two GPS/GLONASS antennas, the VBOX 3i RTK measures all of the normal VBOX GPS parameters, plus the azimuth and elevation between the antennas, i.e. the direction the antennas are pointing, and the angle between them measured from the horizontal. This allows the unit to measure slip angle, and also pitch angle (or roll angle depending on how the antennas are mounted), all at 100 Hz.
Both the VBOX and the Base Station track the Russian GLONASS range of navigation satellites as well as the normal GPS constellation, using almost twice as many measurements for accurate results and reception in areas of poor satellite visibility. Read more on VBOX GPS accuracy.
VBOX 3i Dual Antenna RTK comes with a VBOX Manager, a display enabling you to change the dynamic modes and filter settings, set up slip angle data and define antenna locations.
A Dual Antenna Mounting Pole (needs to be ordered separately) ensures optimum antenna separation and the most accurate attitude measurement.
