Notice on GPS Positioning Issues in Devices with MTK 2503D Chips
Recently, some of our GPS devices equipped with the MTK 2503D chip have encountered abnormal positioning behavior due to a GPS week rollover issue. This results in the device time resetting to January 1, 2006, and unstable positioning performance in certain cases. While 4G devices remain unaffected, our team is actively collaborating with MTK to develop a permanent firmware fix. In the meantime, we have prepared both server-side correction methods and recommended terminal-side settings to minimize the impact on users.
