Galileo receivers capable of tracking this signal will benefit from unequalled performance in terms of measurement accuracy and multipath suppression. However, the signal processing techniques required to process the AltBOC modulation are much more challenging than those for the traditional BPSK or even for the usual BOC modulation. This stems from the extremely large bandwidth and from the complex interaction of 4 components of the spreading code. Despite a high number of publications on the tracking of other Galileo signals, little has been published yet on the tracking of AltBOC. The purpose of this paper is to present the principles of tracking and receiver-side processing for the AltBOC(15,10) signal . First, the signal structure is discussed in detail. Then the principle of demodulation and the architecture of the tracking channel are discussed alongside with related algorithms. The hardware implementation of the prototype receiver is presented as well. Finally, the impact of various error sources on the tracking performance is evaluated.
