产品介绍
ER-DFOG-50 Low Cost Double Axis Fiber Optic Gyro (FOG) is a very important angular rate sensor, which has the characteristics of long life, fast start up, high precision, lower power consumption, wide dynamic range and so on. The FOG gyros can determine the orientation of moving objects, as an inertial navigation instrument, and it is widely used in modern aviation, navigation, aerospace and defense fields.
Applications
Servo tracking、 medium precision INS、 platform stability
High-speed rail track detection、photoelectric pod
Satellite communications
On-the-move (SOTM)
Unmanned Vehicle
