Pollux 2 Inertial Navigation System

Micro-Miniature Navigation Solution For Unmanned Ground And Aerial Applications

Product lifecycle status: 

Pollux 2 is a compact GNSS aided inertial navigation system based on MEMS technology. It offers unmatched performance and is highly suitable for guidance, navigation and control applications in unmanned aerial and ground vehicles (UAVs and UGVs). 


It performs very well in short term GNSS outages, in forest canopies and urban scenarios.  The PLX2 – NS20 model deliver 2.5 cm position accuracy in RTK mode.


Pollux 2 weighs just 80 grams and can be a perfect navigation payload for UAVs and a position tracking tool for smart soldiers.


Pollux 2 combines Aeron’s Kalman filter-based parameter estimation engine with high-speed processing power to deliver position, ground speed, and orientation information at 50 times per second. Pollux gives Industry-leading navigation performance with the help of the latest MEMS (Micro-Electro-Mechanical System) sensing technology and multi-constellation GNSS.
