Application of pressure sensor in Chinese area positioning system

In the proof-of-concept phase of Chinese Area Positioning System (CAPS), the user receiver can calculate local altitude and further achieve three-dimensional positioning by pressure sensor which can be used to measure atmospheric pressure and temperature. Additionally, the meteorological parameters, such as atmospheric pressure, temperature and humidity, can be resorted to analyze tropospheric delay from the satellite to the user. In this work, the MS5534C barometer module is applied in CAPS. The results show that positioning and navigation with a high performance can be achieved, which can well satisfy the requirements of the common users. © 2012 Springer-Verlag GmbH.
