Abstract
A device comprising a reception unit for automatically receiving two radiofrequency signals originating from different satellite-based positioning and date-stamping systems, a data processing unit for automatically processing each of the radiofrequency signals so as to deduce time data therefrom, each time datum comprising at least one number of weeks, a calculation unit for automatically calculating a UTC date which is compatible with these time data, and a data transmission unit for automatically providing this UTC date to at least one user system.
Claims10
A method of determining at least a date relating to a coordinated universal time, a so-called UTC date, comprising at least the following successive steps, comprising an automatic manner:
- a) receiving, for one and the same time, at least two different radiofrequency signals, a first of said radiofrequency signals originating from a first satellite-based positioning and date-stamping system, and the second of said radiofrequency signals originating from a second satellite-based positioning and date-stamping system, which is different from said first satellite-based positioning and date-stamping system;
- b) processing each of said radiofrequency signals so as to deduce time data therefrom, each time datum comprising at least one number of weeks;
- c) calculating a UTC date which is compatible with these time data arising from the two radiofrequency signals, said UTC date indicating at least one year;
- and
- d) providing this UTC date to at least one user system.
A device for determining at least a date relating to a coordinated universal time, a so-called UTC date, which comprises:
- at least one reception unit configured to receive automatically, for one and the same time, at least two different radiofrequency signals, a first of said radiofrequency signals originating from a first satellite-based positioning and date-stamping system, and the second of said radiofrequency signals originating from a second satellite-based positioning and date-stamping system, which is different from said first satellite-based positioning and date-stamping system;
- at least one data processing unit configured to process, automatically, each of said radiofrequency signals so as to deduce time data therefrom, each time datum comprising at least one number of weeks;
- at least one calculation unit configured to automatically calculate a UTC date which is compatible with these time data arising from the two radiofrequency signals, said UTC date indicating at least one year;
- and
- at least one data transmission unit configured to provide, automatically, at least this UTC date to at least one user system.
