IG-500N: GPS aided miniature INS

The IG-500N is the world smallest GPS enhanced miniature Attitude and Heading Reference System (AHRS). With its embedded Extended Kalman Filter, the IG-500N delivers unmatched precision on attitude and position measurements in very high dynamic conditions.

AHRS and Navigation sensor!

The IG-500N includes a MEMS based Inertial Measurement Unit (IMU), a GPS receiver and a pressure sensor. It provides a precise and drift-free 3D orientation and position, even in high G maneuvers at high updates rates, up to 100 Hz.

Thanks to an advanced individual sensors calibration procedure associated with an onboard Extended Kalman Filter (EKF), this miniature Inertial Navigation System (INS) provides a very accurate 3D orientation and position.

By removing transient accelerations measured by the GPS receiver, the delivered attitude is better than 0.45° RMS making this device a good alternative to expensive FOG-based AHRS.

END-OF-LIFE

The IG-500 Series is not recommended for new design.

SBG SYSTEMS offers the Ellipse Series as a replacement for IG-500 series.

The Ellipse Series is more accurate, more robust, and more versatile, for the same price level.

SmartFusion Makes Sensor Integration “As Easy As a Click”:

SmartFusion Motion Profiles include more than Kalman Filter parameters; they also adjust automatically to Vibration level, Dynamic model, Magnetic disturbance immunity, and specific application constraints.

Moreover, the interface gives customers the freedom to choose some advanced parameters, and offers useful suggestions such as Recommended heading sources or Placement requirements.

Available Motion Profiles: Airplane, Helicopter, Automotive, Marine, Underwater, etc. A customized profile can also be designed for a specific environment.

Applications:

Performance sailing

Sailing races are very demanding applications where performance and robustness are critical. The IG-500N is used to help skippers taking the most of their boat.

The low weight, low power consumption of the IG-500N is also very important to maximize boat performance.

UAV stabilization

Thanks to its high performance and small size, the IG-500N is a perfect solution for stabilization and navigation of large to miniature Unmanned Aerial Vehicles.

The outputted 3D orientation and position can directly feed an autopilot system letting you focus on your application.

Car motion analysis

The IG-500N combines an embedded GPS receiver and an Inertial Measurement Unit (IMU) to provide accurate and robust 3D orientation and position at high update rates.

This device is a good solution to measure and analyze car motion, such as chassis roll over detection, optimal trajectory determination, over and under steering characterization.

Aerospace industry

The high accuracy of the IG-500N attitude, its very small size, low power consumption and low cost enable new application fields in aviation industry.

In an amazing small package, the IG-500N advantageously replaces the Attitude, Heading, Turn/Bank, Vertical Speed, and even Altimeter indicators.
