Centimeter-scale GNSS Systems – Efficient and Secure Implementations

Global Navigation Satellite Systems (GNSS) augmentation techniques such as differential GNSS and real-time kinetic (RTK) positioning have been critical for GNSS accuracy and usability. In a typical scenario, the correction data is streamed to a device in the field (rover station) from a reference (base) station. However, as the number of devices that rely on location service increases dramatically with the emergence of Internet-of-Things (IoT), a secure and efficient system to handle high-throughput traffic is needed.
In this project, we investigate a scalable and reliable GNSS augmentation system with accuracy down to a centimeter level and high-resilient to high traffic. The system will be implemented using the Internet- based NTRIP that support multiple protocols (RTSP, TCP, and UDP) for communication and data transmission, and SSL certificate for authentication and encryption. A high-throughput relay will be designed with the aim of providing high availability. TO BE CONT’D
