Dual Axis FOG Gyroscope
Biaxial Fiber Optic GyroscopeNS series Fiber optic gyroscope is designed with concept of traditional fiber optic gyroscope. Adapting matured fiber optic gyroscope manufacturing technology, NS series fiber optic gyroscope with characteristics of small volume, light weight, low power consumption, fast start-up, simple operation, convenient to use etc. NS series FOG use the principle of interference of Sagnac, make the laser as light source, light path of loop type is constructed by fiber, and inspect phase differences of two routes laser beam, the phase differences was caused by two beam (two beam from the pro and con hour hand was transmitted along optical fiber) rotated along with fiber loop, then will calculate the rate of angular speed of the optical gyroscope.Application:● Optical pod/Flight control platform● SINS / IMU● Platform stabilization device● Position marker control system● North finding instrument● High precise measurement/ navigation system and servo systemNo.ParameterNS-502 BiaxialUnit1Measurement range-1000～+1000(º)/s2Bias stability3.6～10.8(º)/h3Bias repeatability0.001～0.003(º)/h4Scale factor non-linearity (1σ)≤200ppm5Scale factor misalignment (1σ)≤200ppm6Scale factor repeatability (1σ)≤200ppm7Power supplySingle +5V8Bandwidth≥500Hz9Run-up time5s10Output formatRS42211External interface9 PIN12Operating temperature-40～+60℃13Vibration6.06, 20～2000g(RMS), Hz14Dimension50×50×59mm³15Weight≤200g16Threshold value≤3(º)/h17Random walking coefficient≤0.05(º)/h½18Impact strength100, 6～8G, ms19Power consumption≤4W20Random walking5s
