Abstract:	This paper aims to introduce and assess the latest version of an open-source collection of Software Defined Radios for Global Navigation Satellite Systems receivers. Each SDR implementation is subjected to an extensive test campaign with the objective to determine its signal acquisition, tracking, navigation data demodulation and positioning accuracy characteristics. The paper describes the structure of the SDR collection, the adjustments made to code-bases to improve their performance, as well as the figures of merit considered to evaluate the obtained results for each test-case.
