VB3i IMU Kalman Filter



VBOX 3i has the capability of integrating the GPS data with inertial data from the IMU03 or IMU04 Inertial Measurement Unit in Real-Time, allowing accurate filtering and smoothing of the following parameters:

  • Latitude
  • Longitude
  • Velocity
  • Heading
  • Height
  • Vertical Velocity

The advantage of VBOX 3i - IMU integration over non-IMU Kalman filtering is that the Kalman filter is using physical inertial measurements from the IMU and GPS engine together. This allows it to rely on IMU data when GPS signal quality is bad or absent (for a short duration).
