Canopus Compact Inertial Navigation System

Canopus inertial navigation systems are compact, rugged and light-weight AHRS and INS-GPS for airborne applications as well as other emerging applications like autonomous vehicles, robotics etc.

Being compact in size, Canopus Compact Inertial Navigation Systems are highly recommended for applications where space is a constraint. Use of extended Kalman filter assures best-in-class MEMS performance in dynamic environments. These systems integrate air data input, barometer, low-bias instability gyroscopes, accelerometers and magnetometer for precise and seamless navigation experience.
