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.

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.
