Query: Versatile Land Navigation Using Inertial Sensors and Odometry:
  Self-calibration, In-motion Alignment and Positioning   Inertial measurement unit (IMU) and odometer have been commonly-used sensors
for autonomous land navigation in the global positioning system (GPS)-denied
scenarios. This paper systematically proposes a versatile strategy for
self-contained land vehicle navigation using the IMU and an odometer.
Specifically, the paper proposes a self-calibration and refinement method for
IMU/odometer integration that is able to overcome significant variation of the
misalignment parameters, which are induced by many inevitable and adverse
factors such as load changing, refueling and ambient temperature. An
odometer-aided IMU in-motion alignment algorithm is also devised that enables
the first-responsive functionality even when the vehicle is running freely. The
versatile strategy is successfully demonstrated and verified via long-distance
real tests.
