Domestically-produced Jetliner with Beidou navigation system successfully completed Test Flight

The Commercial Aircraft Corporation of China (COMAC) said on October 14th that 103 plans of Chinese-developed and designed regional jetliner ARJ21-700, which have the BeiDou navigation system installed, have successfully completed the test flight. The test flight was carried out from Dongying airport in east China's Shandong Province.

The flight tested the performance of the onboard navigation information receiver, the ground-based signal enhancement system, and the short-message function of the BeiDou system.

The results showed the performance of the navigation systems developed by China is on par with similar systems produced abroad, and even reaches internationally advanced level in transient and quick positioning index.

It was the first time a domestically-produced regional jet has been equipped with the BeiDou navigation system, the ground-based signal enhancement system and onboard navigation system. This has obtained a large amount of experimental data for Beidou's standardization in international civil aviation, promotion of application, testing and certification.

It was the first application of Beidou in the field of civil aviation as well as the first time a domestically-produced regional jet has been equipped with the BeiDou navigation system, which is of great significance to the integration and development of the two major projects.

COMAC said that the company will continue to follow the development of the Beidou satellite navigation system in the process of coordinating the development of mainline aircraft and regional aircraft and make use of its own advantages to promote the research and application of the Beidou test flight projects.
