Global Navigation Satellite System (GNSS) is a term used for satellite navigational systems that provide autonomous geo-spatial positioning with global coverage. The Global Postioning System (GPS) is a satellite-based radio navigational system that provides three dimensional navigation solutions, which are position, velocity and timing information, and has revolutionized the field of navigation. Due to the increased demand in navigation, several countries, including the European Union, Japan, and India, have started to develop their own navigational systems.
To provide interoperability between GPS and globally available navigational systems, a new modulation technique called Binary Offset Carrier (BOC) modulation, which provides better accuracy than the existing modulation techniques, is introduced. The BOC modulation comes with two different variants: sine BOC modulation and cosine BOC modulation. This project specifies the differences between these BOC modulations by analyzing their spectral characteristics for different orders of BOC modulated signals, which are used in navigational systems.
