1. A method of providing normalization of time of local clock circuits of two or more spatially-located receivers of respective monitoring stations, said method comprising:

  • transmitting at least two RF pulses to define a time reference interval;

    detecting said RF pulses at said receivers;

    at respective monitoring associated with said receivers, measuring durations of said time reference interval according to said detecting step;

    determining a relationship between durations measured at said monitoring stations; and

    providing normalization of time of said local clock circuits at two or more monitoring stations according to said relationship.
