Starting from the analysis of the measuring principle of atmospheric pressure altitude and the necessity of the pressure sensor temperature compensation, this paper presents the design and realization of an atmospheric pressure altitude measuring system with high performance which use FPGA as the data processor and with the pressure sensor temperature compensation design. Article discusses in detail the hardware circuit design of the measuring system, and the internal structure of FPGA software design. At last, the results of system test verify the feasibility and effectiveness of the atmospheric pressure altitude measuring system. Because of the FPGA’s characteristics of high reliability, strong data processing ability, high speed and so on, and the effective combination of temperature compensation design, the atmospheric pressure altitude measuring system has the advantages of high measuring precision, high reliability, good real-time and low power consumption.
