This paper analyzed the J/S of the GPS receiver in sea environment from GPS satellite and GPS jammer. Through the analysis, the operational range and effective radiation power of the GPS jammer could be estimated. In the case of the jammer effective radiation power is higher than the specific value, jammer height mainly resolves the jammer operational range.
