In this paper, a static pressure calibration device is designed and the method of static calibration with piezoelectric pressure sensors is discussed. According to the theory of PASCAL law, the static calibration device is developed, whose stress ratio is up to 1:25. And this device has been accredited by the authorities. To ensure the consistency of pressure calibration, the improvements on calibration device’s output are made. As a result, we can calibrate up to four sensors at the same time. By means of the pressure calibration device, the calibration method of pressure sensor, the calibration theory, system components and calibration procedures is given. As the test results shown, the corresponding sensors’ static calibration linearity is 0.05%, and its uncertainty is 0.42%. It’s practicable and reliable to make static calibration to sensors by the pressure calibration device.

Precise navigation is often performed by sensor fusion of different sensors. Among these sensors, optical sensors use image features to obtain the position and attitude of the camera. Runway relative navigation during final approach is a special case where robust and continuous detection of the runway is required. This paper presents a robust threshold marker detection method for monocular cameras and introduces an on-board real-time implementation with flight test results. Results with narrow and wide field-of-view optics are compared. The image processing approach is also evaluated on image data captured by a different on-board system. The pure optical approach of this paper increases sensor redundancy because it does not require input from an inertial sensor as most of the robust runway detectors.
