    1. Reconfigurable GNSS Receivers Kai Borre & Darius Plaušinaitis

    2. 2 OVERVIEW Background For Reconfigurable Receivers Solutions, Receiver Types Overview of the DGC‘s SDR Overview of Each Receiver Block Conclusions and Future Vision

    3. 3 OVERVIEW Background For Reconfigurable Receivers Solutions, Receiver Types Overview of the DGC‘s SDR Overview of Each Receiver Block Conclusions and Future Vision

    4. 4 Basic Facts Radio communication: multi-standard, multi-frequency communication in a single, compact device Less hardware components Re-usable hardware Intelligent radios

    5. 5 Basic Facts (GNSS Receivers) GNSS positioning is also becoming multi-standard and multi-frequency GPS II (Since 1980) GPS modernizations: M code and L2C, L5 signals Galileo (possibility to update signals on the fly?) GPS III GLONASS signals are getting updated QZSS (Japan), IRNSS (India), and Beidou (China) SBAS systems: EGNOS, WAAS, MSAS, GAGAN

    6. 6 Basic Facts (GNSS Receivers) Possibility to track signals using non-traditional methods for Multipath mitigation Weak signal tracking (indoor positioning) Fast signal acquisition Very good for prototyping Does not require to wait for a new hardware version

    7. 7 OVERVIEW Background For Reconfigurable Receivers Solutions, Receiver Types Overview of the DGC‘s SDR Overview of Each Receiver Block Conclusions and Future Vision

    8. 8 Solutions To use new hardware per signal Basic components, chips ASIC (Application Specific Integrated Circuit) To use reconfigurable hardware – FPGA (Field Programmable Gate Array), etc. To use DSP (Digital Signal Processor) To use GPP (General Purpose Processor) – x86, ARM 9, etc.

    9. 9 Comparison of Solutions
