Results are compared with standard and high sensitivity GNSS receivers and show a significant improvement in the availability of position solutions when GLONASS is added. An assisted high sensitivity receiver architecture is introduced which enables high fidelity signal measurements even in degraded environments.

The soft approach: a recipe for a multi-system, multi-frequency GNSS receiver / Cillian O'Driscoll in Inside GNSS, vol 4 n° 5 (September - October 2009) 

Public [article]  inInside GNSS > vol 4 n° 5 (September - October 2009) . - 6 p. ; pp 46 - 51 Titre : The soft approach: a recipe for a multi-system, multi-frequency GNSS receiver Type de document : Article/Communication Auteurs : Cillian O'Driscoll, Auteur ; Daniele Borio, Auteur ; Mark Petovello, Auteur ; et al., Auteur Année de publication : 2009 Article en page(s) : 6 p. ; pp 46 - 51 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie spatiale [Termes IGN] application informatique [Termes IGN] récepteur GNSS Résumé : (Auteur) PC-based software GNSS receivers, which have served as powerful research tools for many years, are beginning to find applications outside the laboratory — in such areas as atmospheric modeling and synthetic aperture radar. The article describes the design of a multi-channel software receiver developed by the University of Calgary — challenges, trade-offs, results, and plans for further capabilities. A sidebar describes how the PLAN software receiver worked as a signal-monitoring tool to analyze the L5 signal broadcast by GPS satellite SVN 49. [summary] The modular design adapted for PLAN's software receiver greatly facilitates research in many areas of GNSS signal and navigation processing. The ability to quickly add new signals, new systems, and new signal processing techniques was a fundamental goal of the design process, and the success of this approach has been demonstrated through a number of examples. A common misconception suggests that a software receiver designed entirely in C++ would be too cumbersome and slow to operate in real time. On the contrary, the PLAN receiver can operate in real-time with up to 12 channels at sampling rates of over 16 Msps. Much research and development work remains to be done, even within the constraints of the software receiver as defined in Figure 2, and certainly a whole world of possibility exists beyond this specific definition. Signal quality monitoring, high-sensitivity operation, atmospheric modelling, and synthetic aperture radar applications are only a few of the potential further uses of the software receiver. We also recently commenced development of a graphical user interface (GUI) to replace the current console interface. Although this development does not contribute directly to the research goals of the PLAN group, the ability to visualize receiver data at run-time can be very useful for quick identification of interesting phenomena, such as RF interference.
