Beschreibung
Zusammenfassung:	The invention provides a method for generating a spread spectrum code in a satellite navigation system in the technical field of information processing. In the method, a spread spectrum code is subject to Legendre sequence generation processing and Weil sequence generation processing to acquire a spread spectrum code sequence, and the spread spectrum code sequence is subject to judgment of even cross-correlation and odd cross-correlation to acquire a required spread spectrum sequence. Based on the Weil sequence generation spread spectrum code, the method realizes the requirement of the satellite navigation system to the spread spectrum code, and has the advantages of great number of generation code sequences and good cross-correlation character of the sequence.
