The RM3100 Geomagnetic Sensor is the highest performance sensor in its class with over 10 yimes better resolution and over 20 times lower noise than the leading Hall Effect sensor. It makes precise magnetic field measurements, which enables accurate calculation of heading and orientation.
The earth’s magnetic field provides absolute reference for heading measurements and accurate mo&on tracking. Geomagnetic sensors are used to measure the earth’s magnetic field; however, in real world conditions, the earth’s magnetic field is often distorted by other surrounding fields. System components such as batteries, shielding materials, or motors will distort the geomagnetic field near the sensors. An additional design challenge is the changing magnetic environment that temporarily distorts the field like metal parts in furniture, a passing car, or nearby cell phones and computers. Geomagnetic sensors must first be able to see the different magnetic fields in order for the designer to separate earth’s magnetic fields and compensate for the distortions.

RM3100地磁传感器是同级别中性能的传感器，分辨率超过10倍，噪音低于***的霍尔效应传感器20多倍。它进行***的磁场测量，可以准确计算航向和方向。
地球磁场为航向测量提供参考，准确的跟踪跟踪。地磁传感器用于测量地球的磁场;然而，在现实世界的条件下，地球的磁场往往被其他周边的地区所扭曲。诸如电池，屏蔽材料或电机的系统组件将扭曲传感器附近的地磁场。额外的设计挑战是不断变化的磁环境，使家具，过路车，附近的手机和电脑等金属零件暂时变形。首先，地磁传感器必须能够看到不同的磁场，以便设计师分离地球的磁场并补偿失真。
