01 - VIPS Introduction
Overview
VBOX Indoor Positioning System uses a network of fixed beacons in set locations that communicate with a receiver
(rover) using Ultra Wideband (UWB) to measure position and speed where you cannot use GNSS signals. A minimum of
six beacons are required, and to ensure the optimum accuracy, a site survey must be carried out as part of the
installation, using either a handheld laser or a Total Station (if time is of the essence, a self-survey can also be
performed). Doing so means the exact location of each beacon is known which can then be shared with the rover
enabling it to calculate its location to centimetre level accuracy. The beacons are completely stand-alone and can be
battery powered, making the deployment very rapid.
Up to 250 beacons can be installed within a system, however a maximum of 12 beacons will be used at any one time by
the rover. To receive the best accuracies of position and angles, the maximum number of beacons available to a
solution (12) should be utilised within line of sight to the receiver.
The rover features an integrated VBOX IMU04 (Inertial Measurement Unit) for precise pitch, roll and yaw angular data. It
can also connect directly to an IMU04 enabled VBOX 3i, enabling additional parameters from the vehicle's CAN bus to
be logged. Offering seamless integration between indoor and outdoor environments, the system can be used for high
dynamic applications and the rover will automatically connect to the nearest beacons in range.
The UWB receiver continuously communicates with the beacons and triangulates its position indoors. This data is
combined with the measurements from a highly accurate inertial measurement system, providing a real-time 3D position
and attitude measurement at 100 Hz, to within 2 cm. VIPS can achieve re-acquisition and full accuracy in less than 0.2
of a second, which is considerably faster than GNSS!
The system is designed for high dynamic vehicle test and validation procedures which are normally performed outside
using GNSS. Examples include acceleration, braking, handling, crash testing, tyre testing and ADAS sensor validation.
The system can also be used to fill in gaps in GNSS coverage in areas such as heavy tree cover, tunnels and urban
canyons.
