Abstract:
Inertial sensors and inertial measurement units (IMUs) are widely used in navigation support systems,
autonomous vehicle navigation, and vehicle motion control process. Inertial measurement based attitude determination
and navigation systems are capable of sustaining their accurate operation with high resolution without subjecting to
external jamming and noise conditions. The most vital equipment in inertial measurement system is the IMU. The
required degree of accuracy, resolution and repeatability in angular velocities and accelerations mainly depend on the
implementation technology of the gyroscopes and accelerometers. The paper presents a methodical approach to obtain
better attitude determination for vehicles with low-cost, multiple MEMS-based IMU. The simulated results are based
on the mathematical models of MEMS-based gyroscopes and accelerometers.
