Abstract:
1. An electronic circuit for use with time of arrival signals from a network, the electronic circuit comprising: a position determination unit operable to generate a global time value and to convey a first global time from said position determination unit as an output; a first clock greater than 1 MHz, said first clock operable to be powered on and off; a second clock less than 1 MHz having cycles; and processing circuitry coupled to said first clock and to said second clock and to said position determination unit, said processing circuitry operable to: wherein said processing circuitry is operable to project the relatively-accurate subsequent global time as a sum of products and ratios of time intervals and counter values representing numbers n of clock beats according to a relation where t t T RCPO is number of first clock counts in the time interval T X n n
