Software radio and its applications in GNSS

The paper deals with the Software Radio and its applications in processing of signals of satellite navigation systems. Modern Software Defined Radio (SDR) technology enables to digitalize and process radio signals in programmable digital circuits. The high power programmable DSP and FPGA are implemented. The benefit of discussed architecture is in a software definition of the function and parameters of radio electronic systems. This architecture can be used in GNSS for software implementation of processing procedures of new GNSS signals, like GPS L2 C/A, GPS L5 or Galileo.
