HMC1051为Honeywell生产的双轴磁传感器，可以用来做指南针，电子罗盘等定位系统。 当接上低噪声放大器和12到16-bit（位）模数转换器（A/D）时，使用HMC105X系列传感器可进行极高精度的测量-Production for the Honeywell HMC1051 two-axis magnetic sensor can be used to make the compass, electronic compass, GPS. When connected to the

The open source project DSP_INS is an inertial navigation system on the TI DSP platform TMS320F28335 with MEMS inertial sensors and commercial GPS module. Inertial sensors are actually used only for estimating attitude, heading and velocity.
