Product Description

HEC395 Nine-Axis Dynamic Electronic Compass High-Performance Heading Accuracy 0.5° Unmanned Vehicles




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.

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.

c. Customized NMEA output.
