The DSP-3400 is a single-axis non-ITAR fiber optic gyro (FOG) housed in a durable shielded package. With state-of-the-art digital signal processing (DSP) electronics, the unit delivers extremely low noise (ARW) as well as significant performance improvements in critical areas such as scale factor and bias stability and scale factor linearity.
The versatile sensor features a powerful high-speed digital RS-422 interface with 1000 Hz asynchronous output, and is an excellent choice for use cases requiring FOG output to be transmitted over a longer distance. It is ideal for a range of applications including inertial measurement units, integrated GPS/INS, AHRS, and antenna and gimbal stabilization and pointing.
