ER-E2 is specially designed for borehole drilling field which has overcame the following technical difficulties, especially its operating temperature up to 100 degree centigrade. Inertial devices are more adaptable and better applied in the drilling field than they are in aviation field due to its ability of working in poor conditions. The life of DTG and its adaptation in temperature are specified, especially when it is used in higher temperature.

ER-E6 is of medium and low precision. The volume of domestic flexible gyro is the smallest, the mass is extremely light, the starting speed is fast (3s synchronization), and the anti-vibration and impact capability is very strong.It is suitable for weapon systems with extremely demanding environments such as projectiles, light and micro navigation, and also for special vehicle control in special environments.
