VBOX 4 Dynamics
VBOX 4 Dynamics
Dual Antenna incorporates a second GNSS antenna, enhancing its utility in dynamic vehicle testing by measuring body heading, slip angles, and pitch or roll movements at 100 Hz.
This model is perfectly suited for advanced handling tests, including ESC assessments, Lane Change manoeuvres, and precise Tyre Testing, providing essential data on vehicle dynamics and stability.
It is ideal for handling tests such as ESC (Electronic Stability Control), Lane Change and Tyre Testing where slip angle is required.
