Latest Patents
Kajikawa's latest patents include innovative methods for improving GNSS technology. One of his patents is titled "Switching tracking loops inside GNSS receiver based on adjustable switching threshold." This invention provides a method for switching between Phase Locked Loop (PLL) and Automatic Frequency Control (AFC) tracking loops within a GNSS receiver. The receiver acquires signals from satellites and adjusts its tracking based on external conditions that affect decoding performance. By updating the switching threshold and comparing signal strength, the receiver can select the most effective tracking loop to generate accurate measurements and decode satellite data.
Another notable patent is "Resilient ephemeris decoding of GNSS satellite information." This invention outlines a positioning system that decodes ephemeris data from satellites and estimates their positions over time. If the estimated position deviates significantly from the expected position, the system excludes this data from its calculations, ensuring more reliable positioning by utilizing corrected ephemeris data.
