- Abstract
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 environment on gravity-influence's parameter measurement, the parameter ξ is taken into a related measurement 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 ΔEG and the parameter ξ on the deflections of electric axis is same, and ΔEG and ξ can't be separated by the Reverse method. In order to eliminate 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.
