Latest Patents

Wang holds a patent for a "Method and device for tracking weak global navigation satellite system (GNSS) signals." This invention describes a GNSS receiver capable of tracking weak signals from multiple GNSS satellites. The method involves closing code and carrier tracking loops around estimates from an acquisition mode. During tracking, early, prompt, and late copies of the code replica are correlated with incoming signals. The prompt correlations are integrated over an extended interval for accurate data bit edge and sign estimation, while early and late correlations assist in code error discrimination. This innovative approach allows for precise timing and position fixing by updating code delay and carrier phase and frequency errors.
