AI Technical Summary

Technical Problem

Existing navigation systems are prone to satellite navigation signals becoming unusable or experiencing a sharp decline in accuracy in complex electromagnetic environments, urban environments with obstruction, or under conditions of active interference and deception. Furthermore, they cannot be effectively applied in underwater scenarios, resulting in poor environmental adaptability.

Method used

A composite navigation system is adopted, combining a gyroscope module and a microelectromechanical array module. By detecting the gyroscope angular velocity, array angular velocity, and acceleration, accurate angular velocity and acceleration are generated for real-time navigation calculation. The redundancy of the array board and the high precision of the gyroscope module complement each other to improve the system's accuracy and stability.

Benefits of technology

It enables high-precision real-time navigation calculations in various complex environments without the need for external satellite signals, exhibiting high stability and accuracy.
