Featuring the latest multi-constellation, multi-frequency GNSS receiver, VBOX 3iS delivers robust location and position data. Accuracy is further enhanced by the internal high-grade Inertial Measurement Unit (IMU) which smoothly fills any gaps in GNSS reception for short periods of time. For longer periods of occlusion, VBOX 3iS utilises the wheel speed data from the vehicle’s CAN bus to significantly reduce any drift.
VBOX 3iSDR builds on the great features of the VBOX 3iS and adds a dual antenna and RTK (Real-Time Kinematic).
The 100 Hz multi-constellation, multi-frequency GNSS engine tracks both the GPS and GLONASS networks of satellites and ensures that data is accurately captured, even in restricted sky view conditions.
In GNSS denied environments, such as tunnels and deep urban canyons, VBOX 3iS significantly improves the accuracy of the estimated speed and position data by combining wheel speed information with GNSS and inertial data.
RTK accuracy combined with the IMU makes VBOX 3iSDR a versatile Motion Pack, providing the speed, position and attitude data required to control driving robots and guided soft targets (GST).
VBOX 3iSDR is highly effective for use in multi-target ADAS testing, such as swarm testing, where an accurate data source is essential for each target vehicle but does not require individual logging capabilities.
The internal high-grade IMU offers precise measurements of pitch, roll and yaw and helps fill GNSS gaps for short periods of time caused by obstructions such as heavy tree cover or bridges.
Wheel speed data from the vehicle’s CAN bus is used to significantly reduce any drift in the data and stabilise the accuracy of speed and position without fitting expensive external wheel speed sensors.
The small size of VBOX 3iS makes it ideal for simple installation on target platforms and GST’s where space is at a premium.
Both variants of VBOX 3iS offer a 100 Hz update rate, use the very latest GNSS technology and include an integrated IMU and wheel speed CAN bus connection. However, you have a choice whether you require the standard VBOX 3iS with single antenna or the VBOX 3iSDR with dual antennas and RTK.
VBOX 3iS is an extremely cost-effective solution for ADAS validation, steering robots and autonomous vehicle testing, and can also be used for conducting performance, braking and benchmarking tests. It has an oversampled event marker to precisely capture the start of tests such as braking.
In areas with limited or no satellite signal (such as tunnels or test tracks surrounded by trees), the VBOX 3iS can fill in the gaps for prolonged periods of time – allowing you to continue testing without having to worry about erroneous data.
*95% CEP (Circle of Error Probable). 95% of the time the position readings will fall within a circle of the stated radius.
