Fiber Optic Gyroscope (FOG)
NEDAERO’s FOG family FOG60, FOG70, FOG80N
NEDAERO introduces: the Fiber Optic Rate Sensor FOG
The NEDAERO Fiber Optic Rate Sensor FOG is a small palm of the hand-sized rate sensor. It provides turn rate for one rotational axis. The modular design allows a cost-effective realization of single or multiple sensing axis units.
Successful development of High Performance FOG80N!
September 2020 – Our FOG-team is proud to announce that development of a High Performance Fiber Optic Gyro has been successfully completed. A new design has led to FOG70 and FOG80N, whereby FOG80N has a Stability @ Room Temperature of ≤ 0.2 °/hr. With this accuracy the FOG80N is suitable for high end stabilization and navigation solutions, which is often found in military applications. Another key feature is that the design is ITAR free.
At NEDAERO we are continuously striving to improve our products and innovative solutions.
NEDAERO has a family of 3 FOGs with all unique specifications.
The (absolute) Scale-factor, Angle Random Walk and Bias Stability all have been improved.
All models are available and ready for delivery from stock.
Early 2018 NEDAERO has validated its Fiber Optic Gyro sensor for the aerospace industry. The FOG60 model has been successfully certified for a commercial airline program, and is now in series production. It’s a 100% European product whereby all materials are purchased from European suppliers.
The sensor is suitable for flight stabilization and attitude control of aircraft, helicopters, drones and missiles. Further application comprises Inertial Measurement Units and Navigation Systems. Other application examples comprise azimuth measurement of land vehicles, optics or antenna stabilization as well as high dynamical sensor platforms or other industrial purposes.
A Fiber Optic Gyroscope can be used in aircraft and helicopters, but has also other application fields like ground vehicles, robots, optics or RF antenna stabilization and training simulator stabilization and high dynamical sensor platforms or other industrial purposes.
The base consists of a spool on which an ultra-thin glass fiber is winded in two directions. By measuring the phase-difference of two light beams, a Fiber Optic Gyro (FOG) calculates the speed in degrees per second with which it provides the turn rate of one rotational axis. Whenever FOGs are placed along the x-, y-, and z-axes, angular rates are measured in three dimensions. Three FOG’s can be combined with three acceleration meters to end up as an Inertial Measurement Unit (IMU). An IMU shows the acceleration and angular rate in three dimensions. The unit can be used for attitude control and navigation of missiles, drones, etc. Once you connect the IMU to a computer, you can determine the orientation, positioning and speed of the object. This system is called an Inertial Navigation System (INS). This system operates autonomous from a GPS system.
The FOG contains no moving parts and has obviously hardly any signs of wear. It has a high reliability and has a forceful, robust design. The modular design enables tuning of specifications to customer specific applications, e.g. dynamic range, bandwidth, bias-stability, noise and physical/environmental specifications. Conventional mechanic gyroscopes will be replaced more and more by this reliable and maintenance-free Fiber Optic version.
