Design of Component-Based GNSS Multi-Band IF Signal Generator

Abstract

Recently, many advanced countries show a great interest in Global Navigation Satellite System (GNSS). GPS of USA, Galileo of Europe and GLONASS of Russia are its representative systems (Kim et al. 2004). If various GNSS signals are provided by these modernization plans, the users can receive multi-band signals and perform better navigations. However, processing newly added signal is accompanied by the development of new algorithm. In addition, an algorithm to ensure the interoperability between different systems is, also, required. To develop and validate these algorithms, the signals to satisfy GNSS signal standard are required. However, since Radio Frequency (RF) signals without Full Operational Capability (FOC) cannot be collected, the studies are restricted. Even though RF signals are collected, a signal generator must be developed to satisfy the GNSS signal standard because the signal cannot be collected from diverse user environment.

Assessment of Radio Frequency Compatibility for New Radio Navigation Satellite Service Signal Design in the L6-Band

“…In this paper, a MATLAB-based signal generation tool introduced in ref. [18] is used for numerical simulations. The simulator considers the geometric arrangement of the satellites and the receiver to generate the signals, and for this purpose, it uses the RNSS orbit information, the user's location, and the surrounding environmental conditions as input parameters.…”
