Racelogic VBOX Roof Mount IMU Option Coming Soon
Racelogic VBOX Roof Mount IMU Option Coming Soon!
The Racelogic VBOX roof mount imu option allows for an IMU04 to be placed directly on the vehicle roof, co-located with the GPS antenna.
The Racelogic VBOX roof mount imu is securely fastened within the machined acetol enclosure which has a magnetic base to ensure that it stays safely in place. The antenna is placed directly above the IMU, ensuring that the data sources are being measured at the same point.
When using a GPS system with an integrated IMU the crucial aspect of accurately measuring the distance from the antenna (on the roof) to the IMU (normally located on the vehicle chassis) increases setup time and can be difficult to get right. Maximum Kalman Filter performance and best application of lever arm correction requires configuration derived from accurate measurement between the IMU and antenna.
However, co-locating the antenna and IMU the problem is eliminated. By putting the two together and mounting them on the vehicle’s roof there is no requirement to measure the distance between them as you do in a standard setup, and it is easier to install. With the GPS and inertial data sources coming from the same point, this critical measurement no longer needed, leaving only the required translation to – typically – the vehicle’s centre of gravity. This method is easier and isn’t prone to human error.
