Ms Kity

Heading accuracy 0.5~0.8deg , Tilt angle +/-90deg ,Wide temperature : -40℃~+85℃

General Description

DCM301B is a high precision 3D electronic compass using the 2D plane calibration algorithm, the

calibration no need 3D posture tilt , just flat-situ rotation a circle to complete the calibration process.

Using USA patented technology of hard magnetic and soft magnetic calibration algorithm, make the

compass eliminate the magnetic influence through calibration algorithm in the magnetic interference

environment ,DCM301B integrated three-axis fluxgate sensor, in real time solver heading through the

central processor, and using 3-axis accelerometer to proceed heading compensation for the wide range

tilt angle, to ensure the compass still can provide high-precision heading data when the tilt angle up to

±85°.Electronic compass integrated high-precision MCU control, various output mode, standard

interfaces including RS232/RS485/TTL and other interfaces, and accept other communication interface


DCM301B with small size, low power consumption, can be used for the antenna stability, vehicles,

systems integration and other more fields , high shock resistance, high reliability makes the compass

work properly in extremely harsh environments, and is more suitable for nowadays miniaturization

military high-precision measurement integrated control system.
