The Europearl Commission has said Galileo will primarily be used for transportation technology, scientific research, land management and disaster monitoring.

This second signal is designed to withstand localized jamming and will be used by police and military services in Europe. European Commission(12)have said China will not be given access to the PRS.

选项
A、speed
B、direction
C、distance
D、location
答案
D
解析
通篇文章谈的都是定位系统,所以,地面接收借助定位系统来定位,所以要选position。其他三个选项(speed,direction,distance)都不符合上下文所表达的意思。
