pseudo body-fixed system

But the data of the file provide with the Geographic Frame Coordinate System , so the change of the Global Total Electron Content (IGTEC) maps are certainly influenced by the factors of the earth rotation and the earth pole moving etc.

然而这些数据是在地固坐标系中给出的,因此其中的全球电离层TEC图像数据的变化必然会受到地球自转、极移等因素的影响。

We studied the biases estimation and sensor registration of sensor network by using Earth Centered Earth Fixed(ECEF) coordinates as unified coordinates.

采用地心地固坐标系作为统一坐标系,研究了多传感器组网中的配准估计问题。

Taking Earth Centered Earth Fixed(ECEF) coordinate as common grid,this paper discusses bias estimation in 3-D sensor network according to the superposition of the same target in different sensors,the linearized measurement equation of range,range gain,azimuth and elevation deviation of each sensor can be derived via the first order Taylor series expansion.

采用地心地固坐标系作为统一坐标系,研究了3-D传感器组网中的偏差估计问题,根据同一目标位置在各个传感器探测中的迭合条件,运用一阶泰勒展式推导出各个传感器的距离、距离增益、方位角、仰角偏差的线性化公式,利用最小二乘法在线估计出各个偏差量,并实时进行修正,仿真结果验证上述方法的有效性。

An analysis model based on the earth centered fixed coordinate frame is introduced, for achieving a quantitative analysis of Doppler shift characteristics over non-GEO satellite channels.
