An Unambiguous Correlation Function With a Sharp Main-Peak for BOC Signal Tracking
This paper proposes an unambiguous binary offset carrier (BOC) correlation function based on a combination of partial correlations composing the BOC autocorrelation, which has a main-peak sharper than those of the conventional unambiguous correlation functions, thus providing a better tracking performance. From numerical results, it is confirmed that the proposed unambiguous correlation functio...
متن کاملA New Unambiguous BOC(n,n) Signal Tracking Technique*
GALILEO, the major contribution of the European Union to the Global Navigation Satellite System (GNSS), will be both independent and complementary to the current GPS. It is still in its design phase, and while the signals have to be finalized, the main specifications have already been confirmed. The Binary Offset Carrier (BOC) modulation is part of the current GALILEO signal plan. A BOC modulat...
متن کاملNew Unambiguous Boc(n,n) Tracking Technique
Galileo and Modernized GPS have included in their signal structures a new signal modulation: the Binary Offset Carrier (BOC). In the navigation field, this modulation is characterized by the chipping rate of its spreading code (m×1.023 MHz) and the frequency of its square sub-carrier (n×1.023 MHz). As a consequence, it is usually referred to as a BOC(n,m) modulation. The choice of the parameter...
متن کاملUnambiguous BOC Acquisition in Galileo Signal
Galileo will be Europe’s own Global Navigation Satellite System (GNSS), which is aiming to provide highly accurate and guaranteed positioning services. Among several services for separate target groups, Galileo Open Services (OS) are designed for mass-markets, and they will be available worldwide and free of charge for all users. Galileo E1 system has a code period of 4ms which is quadruple tha...
متن کاملAn Unambiguous Tracking Scheme Using Partial-Pulses for BOC Signals
The recent researches on the tracking of binary offset carrier (BOC) modulated signals have been studied focusing on resolving the ambiguity problem caused by the multiple side-peaks in BOC autocorrelation. In this paper, we propose a novel unambiguous BOC tracking scheme with an improved tracking performance by using partial-pulses of BOC signals. Firstly, we observe that a sub-carrier consist...
