VBOX Speed Sensors
With update rates of 25 Hz and 100 Hz, VBOX Speed Sensors provide a high accuracy speed signal to augment your testing setup.
High accuracy GNSS receiver- Brake trigger input
- User configurable analogue + digital outputs
- CAN Bus output
Multi-GNSS
Using high accuracy multi-constellation GNSS receivers, the speed sensors track GLONASS, Galileo* and BeiDou* satellites in addition to GPS, which improves the quality of measurements in areas of poor satellite visibility. (*25 Hz version only)
RS232 Serial Output
Selectable RS232 modes that include NMEA output of speed, position and time.
CAN Bus Output
Data output is via CAN Bus, offering easy integration with data loggers and testing applications. Available channels are position, velocity, distance, time, heading, height, vertical velocity, lat/long acceleration, trigger to zero distance, trigger time, trigger speed, and radius of turn.
Live Data Monitoring
When connected to a laptop or PC (via serial) that runs our free VBOX Test Suite analysis software, you can monitor the test data from your vehicle, in real-time.
Digital Output
Analogue Output
Dust & Waterproof
The aluminium enclosure is IP 66 rated, meaning it is protected against dust and water, and can be used in harsh environments.
Applications
VBOX Speed Sensors are smaller, cheaper and more rugged than the equivalent VBOX range of data loggers, with the same accuracy and quality of signal.
With a length of only 9-14 cm, the unit is easy to mount and transport, making the Speed Sensor perfect for automotive testing, motorsport, marine, and telematics.
All units are housed in the same small, water-resistant package, with connections made via a Deutsch motorsport style connector.
Brake Testing – Using a brake pedal mounted trigger input, the Speed Sensor will measure braking distance to within ±1.8 cm.
Performance & Acceleration Testing – VBOX Speed Sensors are perfect for all variations of performance testing, the accuracy and quick response of the 25 Hz or 100 Hz unit gives very repeatable and accurate results.
Poor GNSS Reception?
Is your test track lined with trees, or does it have bridges and tunnels?
Are you testing on public roads, with multiple objects obscuring the direct view to the satellites?
VBOX 3iS, our speed sensor with inertial and wheel speed integration, significantly improves the accuracy of the speed and position data by combining wheel speed information from the vehicle’s CAN bus with GNSS and inertial data. In areas where there is no view of the sky at all, such as in tunnels, inertial sensors and wheel speeds can fill in the gaps for periods of up to five minutes.
VBOX 3iS also benefits from a 100 Hz multi-constellation, multi-frequency GNSS engine. By tracking the GPS and GLONASS networks of satellites on more than one frequency, it eliminates errors caused by ionospheric effects (one of the major sources of positional error) by simultaneously processing at least two range measurements.
Additionally, the internal, high-grade IMU offers precise measurements of pitch, roll and yaw.
