ntroduction
The TDLG46 laser gyroscope is a small laser gyroscope developed for high dynamic, high shock, high vibration and low cost applications. The unique configuration and reinforcement technology makes the product compact and rugged, with excellent dynamic adaptability.
Feature
1,Good stability of scale factor
2,Strong resistance to shock overload
3,Insensitive to temperature and electromagnetism
4,Small volume, light weight, low cost
Application Scope
It is suitable for medium-precision navigation of short-range tactical missiles, guided artillery shells, long-range weapons, and wireless aircraft.
