AI Navigation Algorithm

The Certus Mini range features Advanced Navigation’s revolutionary AI neural network sensor fusion algorithm.
This provides accuracy levels up to 10 times that of a traditional Kalman filter.
The algorithm was designed for control applications and has a high level of health monitoring and instability prevention to ensure stable and reliable data.
Signal Processing

High-Performance MEMS

The Certus Mini range contains high performance MEMS sensors that are put through Advanced Navigation’s intensive 8 hour temperature calibration process.
This provides the highest accuracy possible from this sensor class and outputs consistent accuracy over the full temperature range from -40°C to 85°C.

Trusted Reliability

Reliability

The Certus Mini range has been designed from the ground up for mission-critical control applications where reliability is essential.
Built using a safety-oriented real-time operating system, all software is designed and tested to high safety standards with fault-tolerance in mind.
The Certus Mini range is designed, manufactured and tested to military standards.

Acceleration Compensation

Linear Acceleration Compensation

Certus Mini uses an innovative algorithm to compensate for linear accelerations.
This allows Certus Mini to maintain accurate roll and pitch through short term linear accelerations that typically cause significant errors in competitors systems.
For long term linear accelerations Certus Mini supports the addition of an external GNSS receiver for full acceleration compensation.

Protocols Interfaces

Extensive Interoperability

Certus Mini seamlessly communicates with a wide range of industry standard protocols including NMEA 0183 and CANOpen making it easy to integrate into existing systems.
Certus Mini effortlessly interfaces with ROS 1, ROS 2, and Ardupilot, streamlining your development processes for maximum efficiency and effectiveness.
