Abstract: Article is devoted the comparative analysis of perspective ways of modulation in broadband radio navigating systems. Comparison of ways of modulation was spent with use of the generalised criterion of spectral efficiency. Results of the analysis of spectral efficiency spread spectrum signals with phase and a frequency modulation are presented. Variants perspective spread spectrum signals providing considerable advantages on a measurement accuracy of a delay in comparison with traditional signals with phase and a frequency shift keying are considered. Recommendations about application of signals for global navigating satellite system GLONASS and terrestrial broadband systems are given.
