IMU05
Inertial Measurement Units O5 ( IMU05 )
The IMU05 (RLVBIMU05) is an advanced inertial measurement unit that offers precise measurements of roll, pitch, and yaw rate through three industry leading high-precision gyroscopes which have a bias stability of 1.2 degrees per hour.
Additionally, it provides X, Y, and Z acceleration data with the help of three accelerometers. The IMU is fully calibrated to account for temperature effects, scale factor, bias, and misalignment errors.
Designed to be versatile, the RLVBIMU05 can be used as a standalone sensor with easy connectivity and configuration options through the CAN or serial interface. Alternatively, it can be used in conjunction with VBOX data loggers, allowing for precise synchronisation to GNSS time.
When utilised as an inertial navigation system (INS) together with VBOX 3i or VBOX 4, the RLVBIMU05 seamlessly integrates IMU data with GNSS to generate accurate position, velocity, and body angles. This integration ensures reliable measurements even in situations where satellite signal reception is disrupted or compromised.
The RLVBIMU05 features a splash-proof casing, rated IP67, which makes it suitable for demanding environments such as boat applications or automotive testing. To maintain the IP67 rating, it’s important to ensure unused connectors are fitted with Lemo blanking plugs (RLACS080).
