SD231 High Precision Optical Fiber Inertial Navigation System

The product is a Strapdown Inertial Navigation System consisting of high-precision fiber optic gyroscope and quartz accelerometer. The main features of the product are as follows:

  1. Quick self-alignment: the fastest alignment time is 2 min, the alignment accuracy is 1 milsecL;
  2. Full navigation parameter output: carrier angular rate, attitude angle, speed, position, etc.;
  3. Inertial self-test function: the key components are self-tested and output in real time;
  4. Integrated navigation function: can be combined with odometer, altimeter, satellite navigation, and built-in GPS / BD receiver;
  5. Autonomous output function: the inertial navigation outputs the navigation parameters autonomously according to the cycle;
  6. Provide real-time ephemeris data: Ephemeris data can be output in real time.
