Pollux 3 INS-GNSS

Pollux 3 is a micro-miniature MEMS-based inertial navigation system combining tri-axial accelerometers, gyroscopes and a magnetometer with an integrated multi-constellation GNSS receiver. An Extended Kalman Filter estimates position, velocity, attitude and heading, with navigation output at 200 Hz. It weighs ~38 g, draws

How Pollux 3 Processes Sensor Data

Sensor and GNSS inputs are fused in real time through Aeron's Extended Kalman Filter to deliver stable position, velocity, attitude, and heading estimates.

Engineered for Compact, High-Accuracy Navigation

  • With DriftLocTM

    When satellites vanish in tunnels, urban canyons, or interference zones, it holds an accurate position and true heading by minimising INS drift.

  • Compact, Tiny SWaP

    Miniature 37 (L) × 37 (W) × 15 (H) mm footprint at ~38 g, drawing under 1.5 W — built for size- and power-constrained unmanned platforms.

  • High Accuracy

    1.5 m CEP position accuracy and 0.1 m/s horizontal velocity accuracy (1σ) with integrated multi-constellation GNSS, including jamming and spoofing detection.

  • Lightweight

    Weighs approximately 38 g, suitable for micro-UAV applications while remaining ruggedized for demanding operating environments.

  • High Quality Sensors

    Uses high-quality MEMS gyros for near-tactical performance and usable GNSS-denied performance during short-term outages.

  • MIL Qualified

    Complied to MIL-STD-810G to perform reliably in extreme outdoor environments of temperature and vibration.

  • Rugged Design

    Ruggedized construction built to withstand the shocks and vibration typical of real-world unmanned-platform operation, such as quadcopter landings.

  • Extended Kalman Filter

    Offers near-tactical performance, providing the best estimates of navigation parameters during short-term GNSS outages.

  • Superior Ingress Protection

    IP65 compliant, able to endure water spray and rain — a reliable solution even when externally mounted.

  • Communication

    Standard RS232 and UART TTL interfaces plus SPI/I²C for external airspeed and magnetometer aiding input, for easy integration with autopilot systems and controllers.
