The 863 Program Earth Observation and Navigation Technology High-Performance Navigation Enhancement Test Signal Simulator and Standardization Technology Project successfully passed the technical acceptance organized by the Ministry of Science and Technology.
Through nearly three years of technical research, the research team broke through the multi-institution satellite navigation signal simulation technology involving high-precision simulation of navigation satellite orbit, precise generation of navigation signals, carrier phase precise control and transmission error simulation; developed as a satellite navigation system and Various receiving devices, especially key instruments developed by high dynamic receivers - multi-system navigation signal analog sources. The Beidou/GPS/GLONASS/Galileo four-system satellite navigation signal simulation source series can provide critical functions for the development, production, application, test and simulation, and simulation training of GNSS receivers and their systems in the laboratory environment. Test and verification support.
The multi-system navigation signal simulation source of this project is a major technological innovation in the field of satellite navigation. It has broken many foreign technology blockades and filled the domestic blank. It has originality, and the core indicators such as the single channel scale (2560 channels) are the world's first. one. The three core products of this achievement have realized the self-controllable and leap-forward development of high-end test applications such as anti-jamming, high-precision differential, high-dynamic real-time closed-loop and so on of China's satellite navigation array, reaching the international leading level.
At present, multi-system navigation signal simulation source equipment has been used for more than 100 units in satellite navigation engineering, major systems, national defense industry research institutes, universities and manufacturers, etc., for satellite navigation measurement and detection system and equipment support. The construction of the system has provided strong support, which has greatly improved the development level of satellite navigation equipment in China, as well as the level of application and industrialization. At the same time, it also provides an important means for China's Beidou system construction, accelerated application and promotion, and enhanced international cooperation. It has enhanced the independent research and development capability and core competitiveness of China's satellite navigation field, and has important political, economic and social significance.
