    • In a geolocation system for determining a geolocation of a target emitter, a method for determining the geolocation. The method comprises receiving a signal transmitted from the target emitter at each one of a plurality of sensors; determining whether signals received at n sensors, from among the plurality of sensors, satisfy one or more threshold values related to a condition of the received signals; if signals received at n sensors satisfy the threshold value, commanding m of the n sensors to transmit the signal received thereat or information related to the signal received thereat to a processor; at the processor, determining time difference estimates for the m received signals and determining the geolocation of the target emitter from the time difference estimates.
    • 在用于确定目标发射器的地理位置的地理定位系统中,确定地理位置的方法。 该方法包括在多个传感器中的每一个处接收从目标发射器发送的信号; 确定在所述多个传感器中从n个传感器接收的信号是否满足与所接收的信号的条件相关的一个或多个阈值; 如果在n个传感器处接收的信号满足阈值,则命令m个传感器将其上接收到的信号或与其上接收的信号有关的信息发送到处理器; 在处理器处,确定m个接收信号的时间差估计,并根据时间差估计确定目标发射器的地理位置。
