Abstract:
A method of synchronizing the transmission of information in assigned time slots between mobile transceiver units having GPS receivers and a base station having a GPS receiver comprising:using said GPS receiver in said mobile units for receiving GPS synchronization data; using said GPS receiver in said base station to receive said GPS synchronization data; using a GPS synchronization pulse generated from said GPS synchronization data to synchronize internal bit clocks in said mobile units and said base station to provide GPS synchronized internal bit clocks in said mobile units and said base station; transmitting base station synchronization pulses from said base station to said mobile units that are synchronized with said GPS synchronized internal bit clock of said base station; further synchronizing said GPS synchronized internal bit clocks of said mobile units with said base station synchronization pulses to produce empirically synchronized internal bit clocks of said mobile units; transmitting data from said mobile units in assigned time slots using said empirically synchronized internal bit clocks of said mobile units.
