In recent years, Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS) have developed rapidly, and their application fields have become more and more extensive. Both GNSS and INS systems have their own advantages and disadvantages in terms of navigation and positioning. The GNSS/INS compact integrated navigation and positioning system gives full play to the advantages of both, improves the overall navigation accuracy and performance of the system, and realizes the incomparable navigation advantages of a single navigation system. It has been widely developed and applied in real-time navigation, vehicle positioning, mobile navigation and other fields.
The GNSS/INS tightly combined system composed of GNSS and INS takes the length of each subsystem: high-precision GNSS information is used as external input, and the INS is frequently corrected during the movement to control the accumulation of its errors over time; The INS positioning results of the GNSS positioning results can well solve the signal loss of lock and cycle slip problems in the GNSS dynamic environment. Not only that, INS can also assist GNSS receivers to enhance anti-jamming capability. When the signal-to-noise ratio is low to a certain level, the GNSS receiver will not work normally, and the inertial navigation system can perform navigation and positioning independently. When the GNSS signal conditions are significantly improved to allow tracking, the inertial navigation system provides the GNSS receiver with relevant initial position, velocity and other information for the receiver to quickly acquire the GNSS code and carrier. The inertial navigation system signal can also be used to assist the direction of the GNSS receiver antenna to aim at the GNSS satellite, thereby reducing the impact of interference on the operation of the system. In addition, inertial navigation systems (INS) can improve the tracking capabilities of GNSS receivers. The navigation information output by the INS at high frequency can well reflect the dynamic behavior of the carrier. Using this information to assist the GNSS tracking loop can significantly reduce the tracking error caused by the dynamic behavior of the carrier, thus reducing the loop bandwidth. This further reduces the tracking error caused by noise.
