Micro Inertial Navigation System IMU / AHRS / INS / GNSS
Small Size, High Precision Plug and Play Excellent Heading Stability Inertial Navigation System DETA 20 Series
Brief Introduction:
DETA20* series is a set of industrial-grade micro-inertial navigation systems based on mems.
The feature of this series is that it adopts redundant sensor technology and integrates a heading gyroscope with a zero bias stability of 2 ° /h, which mainly solves the problem of heading drift.
The series includes IMU, VRS, AHRS and GPS/RTK/INS solutions with rugged metal housings and military-grade connectors.
Equipped with the industry's advanced SPKF nonlinear data fusion algorithm, after professional calibration and temperature error compensation of -40℃~60℃, the algorithm has the ability to resist magnetic interference, and the powerful interface software is easy to use immediately.
This series is especially suitable for mobile robot applications such as drones, ground autonomous vehicles, AGV/AMR, etc.
Features:
■ Redundant heading gyro
■ Heading 0.5˚ RMS, attitude 0.1˚ RMS
■ Typical gyro bias stability 5°/hr
■ Zero offset, scale factor, orthogonality -40°-85° temperature factory calibration
■ Calibration test report
■ Conical rowing compensation, adaptive SPKF
■ 10 DOF 3-axis gyros, 3-axis accelerometer, 3axis magnetometer, heading gyro
■ TTL/ CAN
■ 22x22x8.5mm, 6grams
■ ITAR-free Made in China
DETA20 series products are built in a brand new, miniature, high performance IMU core that has undergone rigorous factory calibration.
The V series outputs attitude and high-precision relative heading and the calibrated IMU raw data,
The A series provides a complete AHRS and absolute heading with magnetic assistance, and the
The N series provides a common protocol interface, allowing users to access sensors such as GPS, Beidou, odometer, and barometer according to application scenarios, with speed and position output.
Characteristics:
The sensors of the DETA20 series include four-axis gyroscopes, three-axis accelerometers, three-axis magnetometers and thermometers, a powerful Sigma-Point Kalman filter (SPKF), and a set of high-performance integrated navigation algorithms, up to 1000Hz Sensor sampling frequency and cone and rowing motion compensation, real-time monitoring of ambient temperature changes, and online estimation of sensor errors, can identify outliers and measurement anomalies and isolate faults, can detect and compensate for structured magnetic fields, and have anti-magnetic interference capability .
Our industry-leading algorithms can easily access external vision, radar and other speed, position, and heading aids for combined navigation, and provide a powerful interactive interface and online calibration algorithms for quick installation and use.
