Pollux 2

Pollux 2 is a complete, tiny SWAP navigation sensor package, for unmanned navigation and control applications. The Pollux 2 packs tri-axial accelerometers, gyroscopes, magnetometer, barometer in a small but powerful MIL qualified hardware.

Aeron’s micro-miniature Pollux 2 INS is a family of extremely compact Inertial Navigation Systems. The units run extended Kalman filter offering near tactical performance providing best estimates of navigation parameters including position, velocities, attitude and heading. Pollux 2 features tri-axial MEMS solid state accelerometers, tri-axial gyroscopes, magnetometer for heading measurement, barometer for pressure altitude, and an integrated multi-constellation GNSS.


Pollux 2 is designed for unmanned aerial vehicles (drones), unmanned robots and ground vehicles, unmanned underwater and surface vehicles and other autonomous applications. Pollux 2 can be easily integrated with a wide range of commercially available autopilot systems such as Pixhawk and Ardupilot.

Gyroscopes And Their Types

Gyroscopes are the most important part of an inertial navigation system or any guidance system. Gyroscopes were invented a century ago and have been used as references to know the inertial state of a moving body. From Kettering bug to the Apollo spacecraft, the quality of gyro has determined the performance of the overall mission. It has been a factor behind ‘make or break’ of the many missions.
