VBOX Speed Sensor Dual Antenna

Posted in Speed Sensors

Overview

Speed-Sensor-Dual VBSS100SLThe Speed Sensor Dual Antenna (VBSS100SL) is a 100Hz GPS/GLONASS system, which combines high level accuracy and test repeatability with the ability to measure slip and pitch/roll angles at 100Hz.

The VBSS100SL can be used for non-contact sensing of velocity providing signal output data on CAN, analogue and digital, allowing easy integration with data loggers and testing applications.

The analogue output can be assigned to vehicle speed, lateral acceleration, longitudinal acceleration, or lap beacon marker with user selectable scaling. The digital output can be configured as either a digital speed pulse output or a lap beacon marker.

VBOX-ManagerWith only 13cm in length, the 100Hz speed sensor is easy to mount and transport, making it ideal for automotive testing, motorsport, marine, and telematics.

The VBSS100SL comes with VBOX Manager, a display which enables the user to setup the dual antenna separation, change the dynamic modes, level and align the antennas.

Inputs

2x GPS Antennas
By utilising two GPS engines configured in a 'fixed baseline RTK setup', true heading, yaw rate, lateral and longitudinal velocity, slip angle and pitch angle can be measured, (slip is measured at the point at which you place the main reference antenna. This can be translated to any point on the vehicle in post processing).

Outputs

  • CAN Bus
    Output Data Rate: 125 Kbit, 250 Kbit, 500 Kbit & 1 Mbit selectable baud rate. Software controlled CAN termination

  • RS232
    NMEA and RL Serial data at up to 100 Hz

  • Analogue Output
    Either speed, lateral acceleration, longitudinal acceleration, or lap beacon output at 0 to 5 V DC

  • Digital Output
    Speed or lap beacon.
    Output Data Rate: Low = 0v, High = 5 V
    Max frequency 4.4 Khz
