Introduction STRAPDOWN inertial navigation system (INS) is typically composed of an orthogonal three-axis set of inertial angular rate sensors and accelerometers providing data to the INS computer. The inertial sensors are directly mounted (strapdown) to the INS chassis structure in contrast with ...

Finally, considering the flight safety, the observability of the proposed visual-inertial navigation system must be analyzed. The main contributions presented in this paper are as follows: we propose a visual-inertial landing navigation method based on SR_UKF in which inertial data, infrared images ...
