Abstract

In this article we present the concept of a FPGA-based GPS receiver architecture with the aim of providing a framework for investigating new receiver architectures for current and upcoming GNSS standards. This development system facilitates researchers to prove new receiver concepts using real signals, which nowadays can only be simulated using tools such as Matlab. One will be able to work with the satellites as soon as they are operational, rather than having to wait for the availability of commercial products. The system allows individual development of signal processing solutions for base-band processing. A soft-core processor implements higher layer services that provide data to the user.
