System-on-Chip FPGA-Based GNSS Receiver

Modern FPGAs offer a cost-efficient alternative to ASICs, and provide the flexibility and scalability to respond rapidly to changing consumer requirements. Soft processor solution such as MicroBlaze makes it possible to integrate a multi-processor system on the single FPGA chip along with the bulk of logic circuitry. Generic FPGA-based architecture of the Global Navigation Satellite System (GNSS) receiver is presented, including a Multi-Processor System, a Multi-Channel Correlator, Fast Search Engine, etc. The generic design is easily reconfigurable for adaptation to various applications such as high-dynamic platforms, or a hard urban environment. Test results of high-dynamic modification of the GNSS receiver are presented, as well as drive test results of the low-cost GNSS receiver option in live hard urban environment are discussed.
