在航天测量船无线电测量设备重力下垂参数标定中常常会受到电磁环境的影响，导致标定结果失真(参数值不可用)。为提高设备的跟踪精度，需获得较为准确的重力下垂参数。设电磁环境影响参数ξ，将参数ξ代入到相关的标定过程中去定量分析影响量，给出了ξ对重力下垂参数的影响量值，同时得到结论：重力下垂参数△EG和电磁环境影响ξ对电轴在方向上的影响相同，反向法无法分离两种误差。为分离两种误差，消除环境影响量ξ，对重力下垂参数标定的工程方法进行了改进，依据误差的包含关系，将传统的对塔方法和跟踪信标球的方法相结合，通过相关数学方法处理得到较为准确的重力下垂参数，经过试验验证，该方法可行，标定结果可信。

Measurement of gravity-influence's parameter of the radio measuring equipment on TT&C ship is usually effected by the electromagnetic environment, and the parameter is certainly wrong as a result. In order to get the correct parameter, a parameter ξ is presumed to express the effects of electromagnetic envi-ronment on gravity-influence's parameter measurement, the parameter ξ is taken into a related measure-ment process to analyze the effects quantitatively, and then the error value of effects is given. The following conclusions are drawn:the effect of the gravity-influence's parameter△EG and the parameter ξ on the de-flections of electric axis is same, and △EG and ξ can't be separated by the Reverse method. In order to e-liminate the errors, the gravity-influence's parameter measurement method is improved. According to the distribution of error, the method of tracing iron tower is combined with the method of tracing air balloon that transmits radio signal, and then the correct parameter of gravity-influence is obtained by mathematical treatment. Practical application proves that this method is feasible and the measurement result is reliable.
