Time Coded Distribution via Broadcasting Stations

S. Leschiutta, V. Pettiti

Abstract:	The distribution of standard time simals via AM and FM broadcasting stations presents the distinct advantages to offer a wide area coverage and to allow the use of inexpensive receivers, but the signals are radiated a limited number of times per day, are rot usually available during the night and no full and automatic synchronization of a remote clock is possible. As an attempt to overcome some of these problems, a time coded signal, with a complete date information, is diffused by the IEN, via the national broadcasting networks in Italy. These signals are radiated by some 120 AM and about 3000 FM and TV transmitters around the country. In such a way, a time-ordered system with an accuracy of a couple of milliseconds is easily achieved.
