. "The new and modernized GNSS navigation systems will provide various navigation services and signals for civil user. The system operators work on basic interoperability agreements which simplify multisystem navigation receiver architecture and reduce its cost. The most current GNSS signals of GPS, GLONASS and GALILEO can be processed by one or several classical EL correlators with a look up table PRN generator of length 10230 chips. Most signals are processed optimally, but for some signals, like Galileo E1b and E1c or GPS L1C, this signal processor does not utilize all signal components and properties. The proposed EL correlator was implemented to the FPGA of the experimental software GNSS receiver and was tested on the GALILEO E1b, E1c and E5a signals. The target multisystem GNSS receiver architecture based on an ExpressCard peripheral card for the standard PC computer or notebook is described in the paper. Up to hundred universal correlators and also signal snapshot capture unit.." . . "GPS; GLONASS; GALILEO; Software Receiver"@en . . . "3"^^ . . . . "Gyroscopy and Navigation" .
