Cold start method for gps module of terminal
A recently granted patent (Publication Number: US11885891B2) discloses a cold start method for a global positioning system (GPS) module of a terminal. The method involves acquiring target position information of the terminal, selecting an ephemeris data record based on the target position information, choosing N satellites to form a visible satellite list, and positioning based on these satellites. The ephemeris data record includes satellite number, elevation angle, and timestamp information. The method also includes acquiring a current target time of the terminal and selecting satellites based on this information. Additionally, the method involves managing failure count values associated with the ephemeris data records for successful or failed positioning attempts.
Furthermore, the patent describes a terminal equipped with a GPS module, processor, memory, and communication bus to execute the cold start method. The processor selects satellites based on the ephemeris data record, target position information, and current target time of the terminal. The terminal also includes features to handle failure count values associated with the ephemeris data records. The method aims to improve the efficiency and accuracy of cold starting a GPS module in a terminal by utilizing ephemeris data records and satellite information effectively. The patent highlights the importance of acquiring precise target position information and selecting appropriate satellites for positioning to enhance the performance of GPS modules in terminals.
