Creating a GNSS Receiver From Free Software Components

Trond Danielsen

Abstract:	A design for a software defined GNSS receiver built from free software components has been proposed. Others have created software defined receivers before, but no complete receivers built from free software and hardware has been created. This paper discusses suitable software and hardware components for such a receiver and suitable algorithms. The receiver uses advanced techniques such as frequency domain correlators, and the number of channels that can be tracked simultaneously is only limited by the computational power of the host computer. An open source receiver represents a unique level of flexibility and potential for researchers and developers. Access to all levels of the receivers gives great opportunities both for students learning about the inner workings of a GNSS receivers, and also for professional users developing advanced algorithms and custom application.
