这款车将遵循差分式全球定位系统以纠正它在电离层和对流层行驶中全球定位卫星信号引起的误差。
The car will be guided by a differential GPS system that corrects errors arising in global positioning satellite signals as they travel through the ionosphere and troposphere.
使用WVR能精确测定对流层时延误差。
Troposphere delay error could be accurately determined using WVR.
但由于对流层中的折射效应，定位系统所测目标的仰角、距离等参量均存在一定的折射误差。
However because of the refraction effect in the troposphere there is refractive error in the parameters measured in positioning system.
主要分析对流层的折射效应对超视距雷达信号定位的影响，并且给出相应的折射误差图（仰角误差和距离误差）；
The refraction effect on positioning of the over-the-horizon radar signal is analyzed. The charts of the refractive error(elevation error and range error) are also given.
最终，模式在整体系统误差上取得较大改进，对流层顶的温度场和风场误差明显减小，降水结构和降水强度显著改进，并且未见“双赤道辐合带”的现象。
Precipitation is dramatically improved both in the amount and the structure. Another advantage is that the false structure of "double Intertropical Convergence Zone (ITCZ)"is not seen in the result.
