“…The units use a pressure sensor LPS001DL by ST microelectronics which cost about 4 USD. Previous tests showed the sensor is capable to distinguish 1 m of vertical distance [7] at the ground level. The complete description of the internal structure of the measurement unit, the wireless interface and its Matlab API is available in [8].…”

This paper describes determination of airplane position angles by usage of five Attitude Heading and Reference Systems based on Micro-ElectroMechanical System pressure sensors. The measurement relates to the properties of the standard atmosphere where the pressure descends with increasing altitude. Because the precision of the measurement strongly depends on the sensor performance the MEMS sensors usually do not provide usable outputs. In this paper we evaluate possibility to use a sensor array whose outputs are statistically evaluated and processed in order to acquire information necessary for altitude measurements and whose outputs will be compared with precision which is required for aviation. The article describes the wireless sensor modules, the data interface and the mechanism used for data exchange with a control station. Last part of the paper deals with possibility to use the statistically processed data from the set of modules for position angles measurements. We summarize technical and economic advantages and disadvantages of this method of positional angles measurement and their applicability for aviation especially for a new concept of blended-wing-body aircrafts.

In this paper we describe a new magnetometer sensor head which is capable to measure the complete calibration circle as one data sample. The new sensor allows for online determination of hard and soft iron distortions and its usage to compensate for their effect on the heading measurement. It provides capability to the magnetometer to compensate for local distortions caused by sensor/aircraft assembly. We describe the construction of the sensor and the influence of the local magnetic field changes will be illustrated. The proposed solution leads to a sensor array and we will describe construction of the single unit and its graphical interface. Then the results provided by the new sensor concept will be presented and the performance of this approach will be compared. At the end we provide method of utilizing the compensated data into an IMU mechanization algorithm where it is used to determine offsets and scale factors of the IMU inertial sensors.

Accurate detection of violations in the process of high‐altitude operation plays an essential role in improving the safety production level of distribution network work. The basis of detecting violations in work at high altitude is to accurately measure the ground height of relevant workers and tools. Therefore, in this study, a method of on‐site elevation measurement in distribution network based on the combination of atmospheric pressure measurement and climbing motion detection is proposed. Through the atmospheric pressure sensor installed on the operator, the accurate value of the altitude change of the operator in a short time can be obtained. At the same time, the acceleration sensor and SVM classifier are used to identify the climbing action of the operator, and the CDHA algorithm is proposed to accumulate the height changes measured by the atmospheric pressure sensor when the operator climbs, so as to obtain the height value of the operator relative to the ground. At the same time, the problem that the height measurement results of the atmospheric pressure sensor drift significantly after a long time of operation is solved. The experimental results show that the average measurement error of the operator's height above the ground by this method is 0.33 m, which is better than the existing comparison methods, and further verifies the validity of the proposed method in accurately determining the height of operator off the ground. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
