A Framework for Real-time GNSS Software Receiver Research

D.A. Godsoe, M.E. Kaye, R.B. Langley

Abstract:	This paper outlines the architecture and on-going development effort of a modular software-based real-time GNSS receiver research framework using the Microsoft .NET Framework and the C# programming language. A pipelined signal-processing model is used to address key timing and inter-module synchronization challenges inherent in working with the parallelism required to simultaneously receive and process four or more satellite signals. An extensible interoperability layer provides clearly defined functional interfaces and simplifies the integration of existing hardware and software components with any stage in the signal pipeline. Various aspects of front-end hardware design requirements, as well as new acquisition and tracking mechanisms, are identified and discussed.
