Attitude and Azimuth Integrated Navigation System AINS-10

 

Featured with independent of outside information, excellent concealment, strong anti-interference, all weather operations, inertial navigation system is a complete autonomic navigation system which could provide diverse navigation parameters. However, its output error is accumulated along with time. Global position satellite (GPS) has higher navigation accuracy, but it is easy to be interfered, suffered from discontinuous output and incomplete output information etc. In order to integrate the advantages of these two navigation methods and effectively improve product performance, as well as strength product's reliability, availability, environment adaptability and dynamics, we utilizing multi-sensor data fusion technology to combine satellite positioning, orientation and inertial measurement, and release new attitude and position integration navigation system.

 

Application

  • Aircraft flight control and navigation

  • Ship-borne & vehicle-borne navigation system

  • Inertial stability control system

  • E-traffic measurement system

  • Industrial & agricultural measurement and application

 

System features

  • High accuracy, no accumulated error, short starting time;

  • Keep higher attitude heading accuracy while satellite signal suffered from jamming;

  • Utilizing dual GPS carrier measurement technology to precisely calculate heading value. Heading accuracy depends on the length of two GPS baseline. Longer baseline, higher directional accuracy.
