Method for improving the continuity in a dual frequency satellite navigation system

摘要

the invention relates to a technique to improve the continuity in a zweifrequenz - satellite navigation system, the method has the following steps:- watch the ionosphere measurements made in two or more frequency bands (s10), and- send a alarmnachricht, be informed on an amendment to the ionosphere, if at least one measurement a change of the ionosphere is the one or more predetermined conditions from (s12).
