The GranStal Solutions GS-SFA-311A - Fiber Optic Gyroscope is a 3-axis FOG that outputs angular velocity and attitude data in the three orthogonal axes of the carrier via an RS422 interface.

The FOG module has been designed as a lightweight system in a small physical volume and has achieved flight heritage.

An ASIC and Anti-fuse FPGA scheme are designed to act as the core of the circuit.

The radiation dose resistance performance of the ASIC chip is 100 Krad (Si), and the SEL resistance is 75 MeV(mg/cm2). The GS-SFA-311A FOG has also passed the Cobalt60 irradiation test at 30 Krad (Si).
