Problems solved by technology

Now the domestic SINS / GPS integrated navigation system has been well applied. For example, the SINS / GPS integrated navigation system produced by AVIC No. 1 Group 618 has been successfully applied to helicopters, while the SINS / CNS / GPS integrated navigation system is limited to digital simulation. In order to realize the SINS / CNS / GPS integrated navigation hardware-in-the-loop system, it is necessary to carry out experimental verification on the aircraft, which is not only costly, but also poor in versatility, so it cannot be realized
Use SINS, CNS, and GPS systems to perform combined calculations after collecting data. When simulating aircraft movement, because the CNS system cannot realize the related movement and identification of star maps, it can only be static simulation or post-processing, and SINS / CNS / Real-time dynamic simulation of GPS integrated navigation hardware-in-the-loop system
