The VBOX Speed Sensors are high-accuracy GNSS speed and position measurement devices, available in 25 Hz and 100 Hz versions. The 100 Hz model (V5) uses a low-latency dual-band GNSS engine with RTK capability, while the 25 Hz model (V2) supports multi-constellation tracking (GPS/GLONASS/Galileo/BeiDou) for improved performance in areas with poor satellite visibility. Both versions deliver reliable measurements for automotive testing and integrate easily.
Applications
- Brake testing: precise speed + trigger-based brake distance.
- Performance testing: acceleration, coast-down, general vehicle dynamics.
