A time dissemination system which distributes time signals over a geostationary satellite has been developed. The developed system utilizes IRIG-B format for time distribution and achieves accuracy figures better than 1 ms over Turkey. Time information in IRIG-B is inserted into the audio channel of digital TV. IRIG-B delay correction hardware is developed to correct the time difference between the time signal received from the satellite and the reference atomic clock on the ground. A standard DVB-S receiver and satellite antenna is sufficient to decode the time signal, omitting the use of any special equipment for the end user.
