Title: Innovations of Gi Wook Nam in GPS Technology
Introduction
Gi Wook Nam is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of Global Positioning System (GPS) technology. With a total of 3 patents to his name, his work focuses on enhancing the efficiency and accuracy of GPS receivers.
Latest Patents
One of Gi Wook Nam's latest patents is a method and system for time to first fix (TTFF) reduction of GPS receivers using satellite-based augmentation system (SBAS) signals. This innovation provides a GPS receiver, a control method for the GPS receiver, and a GPS system that can reduce the initial position check time by utilizing SBAS signals transmitted from SBAS satellites. The control method involves receiving an SBAS signal and calculating the satellite clock and position of the GPS receiver based on this signal. The SBAS signal contains a difference value between the ephemeris data and the almanac data of the GPS satellite, which allows for quicker and more accurate acquisition of current position and time information.
Another significant patent is a system and method for determining protection levels. This system includes a receiver that receives various error augmentations related to satellite orbit, clock errors, ionospheric errors, noise, multi-path effects, and tropospheric errors. It features a first calculator that computes an adjustment coefficient for the satellite orbit and clock error, as well as the ionospheric error. A second calculator then applies this coefficient to determine the protection level.
