Abstract
The paper presents a novel strategy capable to effectively mitigate possible false locks of the receiver tracking stage in case of multi-peak code correlation functions, as for example high-order Binary Offset Carrier (BOC) modulations, used in modern Global Navigation Satellite System signals (e.g. Galileo and modernized GPS). The proposed strategy represents an enhanced version of well-known “bump-jumping” approach and it differs from the other solutions at the state of the art. Simulation results are provided in order to demonstrate and validate the performance and the flexibility of the proposed strategy in three cases: BOC(1,1) (Galileo E1 Open Service), BOCc(15,2.5) (Galileo E1a-like) and BOCc(10,5) (Galileo E6a-like) modulated signals.
