Zusammenfassung:	A method and apparatus are provided for processing navigation signals with improved stability in a multi-frequency, multi-system environment. Satellite signals, which are transmitted by a plurality of satellites from a plurality of different global navigation satellite systems, are received on a common radio path and processed in separate digital satellite channels, with each of the separate digital satellite channels corresponding to a respective satellite signal. A common quartz-locked-loop (QLL) discriminator signal is generated based on correlation signals from each of the separate digital satellite channels. Based on the common QLL discriminator signal, guiding signals are generated, with each of the guiding signals corresponding to a respective one of the separate digital satellite channels, for reducing phase-related tracking errors in the respective satellite signal processed in its corresponding digital satellite channel.
