IMU(惯性测量单元)和GPS(全球定位系统)是两种常用的传感器技术,用于测量姿态和位置信息。IMU通过测量加速度和角速度来确定物体的姿态,而GPS则通过接收卫星信号来确定物体的位置信息。 将IMU和GPS数据结合起来可以提高定位精度和姿态测量的准确性。然而,这两种传感器技术各自存在一定的局限性,比如IMU容易积累误差,而GPS在...

For a micro-electro-mechanical system inertial measurement unit (MEMS-IMU), Global Positioning System (GPS) and magnetometer integrated navigation system, the procedure of initial alignment is a necessity. However, both magnetometer and GPS receiver are

Ignagai assumes a separate and distinct Inertial Sensor System, such as an AHRS, that will be too costly for general commercial applications. The use of an aircraft track heading procedure for initializing the heading measurement process is not generally suitable for platforms where the IMU and ...
