Instead of normalizing time reference of independent spatially-located clocks using a reference tag transmission from known location, the present invention uses an interarrival time interval between a pulse pair of UWB pulses as a timing metric. Thus, a method of synchronizing spatially-located clock or normalizing time indications thereof comprises transmitting a UWB pulse pair, determining at first and second monitoring stations a respective count value indicative of a locally measured time interval between received pulse pairs, determining a ratio bet...
We claim: 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 ti...
