Abstract
The emerging European global satellite system Galileo has gained much public interest regarding location and position services. Two Galileo Open Service signals, namely E1 and E5, will provide the frequency diversity. The dual-frequency receiver will greatly enhance the performance of satellite navigation. However, the dual-frequency receiver becomes more complex since it needs to process two signals. Using common front-end components and common baseband for all the signals is a popular concept in literature in order to decrease the complexity. In this concept, two signals will be combined before the common baseband. The signals will then interfere with each other and the radio frequency (RF) interference in one signal band may also appear in other signal bands after the signal superposition. This article investigates the impact of interference due to the signal superposition on code tracking.
