2019年8月6日 · Essentially it is a 3-1-3 body-two rotation sequence. I talk about the DCM a little more in detail here (Calculate Argument of periapsis of orbit given focus and two points on ellipse). You will need to know all your orbital parameters in order to calculate this DCM though.

The Direction Cosine Matrix ECEF to NED block converts geodetic latitude and longitude into a 3-by-3 direction cosine matrix (DCM). The DCM matrix performs the coordinate transformation of a vector in Earth-centered Earth-fixed (ECEF) axes into a vector in north-east-down (NED) axes.

2023年1月18日 · acc_bias 为机体坐标系下加速度计的偏移量，初始值为0， imu_DCM 为Body2NED转换矩阵， ori_xacc 、 ori_yacc 、 ori_zacc 为加速度计的原始值。 将偏移修正后的加速度转到NED坐标系下，注意所使用的加速度计数据方向与标准方向需一致。 b_acc[0] = ori_xacc - acc_bias[0]; . b_acc[1] = ori_yacc - acc_bias[1]; . b_acc[2] = ori_zacc - acc_bias[2]; for (int i = 0; i < 3; i++) { . ned_acc[i] = 0.0; for (int j = 0; j < 3; j++) { .

Learn how to choose a coordinate transformation function based on your data. Vector transformations differ from coordinate transformations. Find the ellipsoidal height of a point by using its orthometric height and a geoid model. Start with a 3-D feature in ENU coordinates, then transform and combine it with a globe display in ECEF coordinates.
