查询词典 error of measurement

The integrated methods based on GPS observables and Kalman filtering are analyzed, and the integrated error models of using position velocity and pseudurange pseudorange-rate as measurement are analyzed too.

分析了基于GPS信息观测和Kalman滤波技术的GPS和惯导的组合方法，以及用位置速度、伪距伪距率为观测量进行组合的数学模型，推导了系统校正的公式。

Large initial state error and non-Gaussian distribution of state may exist in the deep-space autonomous celestial navigation, so based on the classic six orbit elements, an orbit determination method for deep-space probe is proposed by using starlight angle as measurement information and the unscented particle filter algorithm.

针对深空自主天文导航中可能存在初始状态误差较大、状态分布非高斯分布等问题，基于轨道6根数描述形式，提出了利用星光角距观测信息和UPF算法确定探测器轨道的方法。

It needs only once measurement result,and can converge to the real angle of target in certain initial error range.It is similar to the complex-angle method proposed by S.M.

这种方法仅用雷达的一次测量结果就能使仰角估计在一定的初始误差范围内自适应地收敛到目标的真实仰角。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
