For the first time in the domestic civil aircraft flight system Beidou Positioning international leading index

Original title: the first application of domestic civil aircraft flight test Beidou system, positioning indicators in the leading position in October 10th to 14, in the Chinese Shandong Dongying airport, the Beidou satellite navigation system China developed for the first time in the 103 ARJ21-700 aircraft engine was tested on the test flight, a great success. This picture is the Dongying net the flight test, officially kicked off in the domestic civil aircraft applications of domestic satellite navigation system, opening up a new era of domestic civil aircraft navigation system. According to China fly introduction, the test on the ARJ21-700 platform, in accordance with the relevant international standards and Chinese civil aviation related technical standards, the successful completion of the airborne Beidou satellite navigation receiver function and performance test, the compass ground-based augmentation system to achieve I precision performance in flight test based on Beidou short message function and flight test. Test results show that the performance of domestic related systems has reached the level of similar systems abroad, of which the transient and rapid positioning indicators occupy the international leading position. The flight for the first time with the four "nationalization", the domestic satellite navigation system, satellite navigation system, enhance the foundation of domestic domestic airborne navigation system combined to the domestic civil aircraft platform, access to a large number of experimental data for the follow-up of the Beidou satellite navigation system of the international civil aviation standardization, application, testing and certification. Beidou satellite navigation system for the first time to achieve the test application in the field of civil aviation, is also the first domestic use of domestic civil aircraft navigation system, has milepost significance for integration of the two major projects of development. The company China project led by flying from Beijing civil aircraft technology research center, China commercial aircraft company owned commercial aircraft flight test center, Shanghai aircraft design and Research Institute, Shanghai aircraft manufacturing company limited in Tianjin, Beihang University, 712, Beijing communication broadcasting Limited by Share Ltd novog Co. Ltd. supplier units to participate in research. China fly said, will be in the development of overall aircraft and regional aircraft in the process, and the realization of "Beidou civil aircraft on the shoulder the mission of development goals, keep track of the Beidou satellite navigation system, through a large number of pre research work, and actively use their own advantages to promote the flying project research and application of Beidou test.
