Sub-miniature AHRS & INS The IG-500 is an innovative gyro-enhanced sub-miniature orientation sensor. Specially designed for autonomous vehicles and based on latest MEMS technology, the IG-500 perfectly fits in the control, stabilization and navigation of micro drones, robots or cameras.
Preliminary specifications
Three versions to meet your needs The IG-500A is an Attitude and Heading Reference System (AHRS). It uses 3 gyroscopes, 3 accelerometers, and 3 magnetometers, to provide a drift-free and precise attitude, even in severe conditions. The IG-500G combines in the same miniature package an IG-500A, a GPS and a barometric altimeter. It thus provides precise orientation, as well as a GPS position and altitude. The IG-500N is a full featured Inertial Navigation System : Using the same sensors as the IG-500G, it also fuses GPS and inertial informations through a Kalman filter, in order to estimate GPS enhanced orientation, precise 3D position and velocity. Benefits that make your applications more efficient Precise 3D orientation, even in dynamic conditions Angular rates measured up to 500°/s, ideal for micro-UAVs Individual sensor calibration over full temperature range, misalignments and cross axis effects Magnetometers’ calibration system for both soft and hard iron effects Accuracy and drift free information provided by extended Kalman filter Three communication protocols : RS232, I2C CAN 2.0B Very compact and lightweight design : only 5 grams Very low power design (2.4V-12V input voltage) Advantages taken from the last GPS chips (G and N versions only) Less than 2.5m absolute positioning error High sensitivity : -158dB Fully support DGPS, SBAS and Galileo ready Real time movement detection with relative 1 cm precision (IG-500N only) Fields of use Autonomous vehicles Industry Gyro stabilized cameras Biomechanics Augmented reality / Animation
