1. A method for synchronizing a plurality of radio frequency receivers, the method comprising:

  • a) providing said plurality of radio frequency receivers, each one of said radio frequency receivers being equipped with an ultra high speed clock for clocking a reception of radio signals for said receivers, said receivers being for synchronizing with one another, said ultra-high speed clock having a frequency of at least one gigahertz;

    b) deploying each of said plurality of radio frequency receivers to a single physical location to thereby locate said plurality of radio frequency receivers at said single physical location;

    c) simultaneously activating said clocks of said plurality of radio frequency receivers using a common trigger to thereby synchronize said clocks of said plurality of radio frequency receivers to one another;

    d) placing each of said plurality of radio frequency receivers in hibernation such that each radio frequency receiver'"'"'s clock is operational and continues its clocking;

    e) deploying each of said radio frequency receivers to different locations such that each of said radio frequency receivers is physically remote from each other;

    wherein said plurality of radio frequency receivers are used to determine a time of arrival of said radio signals.
