The article presents data analysis of the short-term and long-term-periodic characteristics of the PPS (Pulse Per Second) signal from the navigation systems. The signal arrival time to the Earth was assessed in relation to a high stability frequency source. The basic statistical properties of the signal were calculated, e.g. mean, variance, autocorrelation and actual distributions of random variables were depicted by using a histogram. The differences have been compared between the quality of the signal from the GPS network, the GLONASS network and their combination. The equipment offered by various manufacturers was assessed. Finally, the impact of the MAV filter (Moving Average) on the characteristics of the random variable was examined. At last, but not least, the autocorrelation was checked.
