The error and algorithms for determining the linear drift coefficient and the constant frequency deviation of highly stable oscillators by the radio signals of space navigation systems are investigated theoretically. The signal frequency instability characteristics of the oscillator and the noise of the radio signal are taken into account. It is shown experimentally that it is possible to determine these characteristics for hydrogen frequency standards.
