On the basis of the high precision radio meteor comparison method (RCM) with the time of radio signals propagation between corresponding points in direct and return directions as a first approximation is considered to be equal (the signal reflected by the “useful” meteor trail exists tens-hundreds of seconds).

At present the RCM along with the methods using transportable quantum clock (TQC) and satellite radio navigation systems (GPS, GLONASS), ensures the comparison error of the order of tens of nanoseconds. In this case the RCM surpasses the indicated methods in such characteristics as the measurements productivity, self-sufficiency, operativeness, efficiency, concealness, stability to ionospheric perturbations [1].
