Abstract:
1. A method of operating a device, comprising a positioning unit and a telecommunications unit, the method comprising: a) requesting a reference time value from a digital telecommunications network; b) starting-up a positioning receiver; c) scheduling a strobe to be transmitted from the telecommunications unit to the positioning receiver by associating said strobe with a predefined value of a first counter; d) comparing a current value of the first counter in a comparator with said predefined value and generating said strobe when said current value of the first counter equals said predefined value; e) recording time of generation of said strobe in relation to a structure of the signal transmitted by said digital telecommunications network in the current serving cell; f) receiving said reference time value from said digital telecommunications network, wherein said reference time value is related to the structure of the signal transmitted by said digital telecommunications network in the current serving cell; g) calculating accurate time of generation of said strobe based on said reference time value; h) transmitting said accurate time of generation of said strobe to said positioning unit.
