GI910 High-Precision Fiber Optic Integrated Navigation System Bias
Stability 0.8 º/h Measurement Range ±10g
Introduction
The GI910 can measure the speed, position, and attitude of the
carrier, and output the compensated angular rate, acceleration and
other information. It has the advantages of all solid state, long
life; large dynamic range, high bandwidth; instantaneous start,
etc.,The regional
adaptability and robustness of the system can be greatly improved.
