Design and Realization of an Intelligent Measurement System for Atmosphere Data

The atmosphere data measurement system plays a very important role in an aircraft system and it provides the height and velocity information and so forth for the flight control system. An atmosphere data measurement system is designed by using the silicon pressure sensor and DSP technology. The mathematics model is established and the architecture method is. put forward in the first place. The system principle and some hardware circuit are presented and the systemic error is analyzed and eliminated. In the end it is realized detailedly. Experiment result illustrates that the system has high measurement precision and reliability and intelligence. The height measurement precision can reach five meter , for example.
