Problems solved by technology

Due to the multi-system characteristics of integrated navigation, relevant tests need to be completed by multiple devices such as attitude unit and satellite unit, and it is difficult to complete the semi-physical simulation test of integrated navigation by relying on a single device
To sum up, the semi-physical simulation test of integrated navigation not only has very important engineering value, but also has certain difficulties

Description

【Technical field】 [0001] The invention relates to the technical field of avionics testing, in particular to a 5G-based integrated navigation remote collaborative testing system and testing method. 【Background technique】 [0002] Integrated navigation system has been widely used in civil aircraft through the complementary advantages of inertial navigation system (Inertial Navigation System, INS) and satellite navigation system. Performance testing of INS / GNSS integrated navigation has been extensively studied by interested parties. Since the test of integrated navigation involves multi-system cross-linking, the semi-physical test of integrated navigation is a common method. Boeing, Honeywell, Texas Instruments and other major manufacturers and component manufacturers benefited from the early start, and carried out flight tests on integrated navigation systems in the 1980s. [0003] From the perspective of the main aircraft manufacturer, airborne integrated navigation equipm...
