HEC395 Nine-Axis Dynamic Electronic Compass High-Performance
Heading Accuracy 0.5° Unmanned Vehicles
Introduction:
Unmanned carrier vehicles often need accurate heading information
when performing complex tasks, but the current attitude reference
system is often easy to lose its direction when encountering
magnetic interference, and the irregular movement process is also
easy to lead to error, even in the static environment. Hec395 nine
axis attitude and heading reference system is an inertial product
of North micro sensor, which provides high-precision roll, pitch
and azimuth measurement in the presence of magnetic interference
and dynamic motion environment. The product includes 9-DOF sensors:
3-axis acceleration sensor, 3-axis magnetic sensor and 3-axis
gyroscope.

FAQ
Q1: Accuracy definition of products
A: RMS accuracy, the accuracy of each product can be
traced.Accuracy test report can be provided if required.
Q2: How to select suitable model?
A: Users should check the following points:
a. Single or dual axis?
b. Commom protocol, Modbus or CAN?
c. Dynamic or static Application scenarios?
d. Horizontal or vertical installation?
Q3: How to purchase?
A: If you want sample, please purchase on BWSENSING online shop. We
accept Paypal/TT/CC.If you purchase in bulk, it is recommended to
consult the sales for the best price.
Q4: How long is the warranty period?
A: One year.
Q5: Precausions for using Electronic compass
A: Please refer to manual, and keep away from sensitive items like
iron or motors, or even your cell phone；Electronic compass outputs
magnetic north, not true north.
Q6: How to calibrate electronic compass?
A: a. Consult Sales about corresponding calibration videos.
b. It is divided into common calibration and 12 point calibration.
The 12-point calibration is only for high-precision electronic
compass.
