ANS-600 Airborne Inertial Navigation System

ANS-600 is a fiberoptic gyroscope based navigation grade airborne inertial navigation system with embedded SAASM GPS receiver which is intended for application to military air vehicles.

ANS-600 has an open architecture and flexible hardware/ software which can be adapted to various air platforms including rotary-wing, fixed-wing and unmanned aerial vehicles.

ANS-600 provides linear acceleration, linear and angular velocity, position, attitude and heading to the host vehicle systems continuously. ANS-600 provides hybrid (inertial + GPS) navigation solution, inertial only navigation solution and GPS only navigation solution simultaneously. ANS- 600 is also capable of using external pressure altitude data to complement hybrid and inertial only navigation solutions.

ANS-600 is designed specifically for airborne applications and it is indigenous design of ASELSAN including the fiberoptic gyroscopes used inside.
