Certus Mini N | Miniature GNSS/INS | Advanced Navigation

Miniature inertial navigation sensors are compact, MEMS-based devices (accelerometers, gyroscopes, magnetometers) designed for precise, real-time tracking of position, velocity, and orientation in constrained spaces . These units, such as the μINS and Ellipse-E , often integrate GNSS for enhanced accuracy in UAVs, robotics, and defense applications.

Key Features and Applications

Technology: Primarily utilize Micro-Electro-Mechanical Systems (MEMS) for miniaturization.
Components: Integrate 3-axis gyroscopes, 3-axis accelerometers, and often magnetometers or barometric pressure sensors.
Performance: Provide high-accuracy, low-drift navigation, often aided by GNSS/GPS, to maintain accuracy during signal outages (dead reckoning).
Applications: Commonly used in UAVs, robotics, autonomous vehicles (UGVs), marine surveying, and defense.
Key Products:
- SBG Systems Ellipse Series : Known for high performance in a compact form factor for marine and land applications.
- VectorNav VN-310 : A tactical-grade, dual-antenna GNSS/INS module.
- Advanced Navigation Certus Mini : Uses AI-based neural network fusion for challenging environments.
- Honeywell Miniaturized IMU (MIMU) : Extensively used in space and defense applications.
