Core Insights - The rapid growth of the NOA market is driving an increase in the installation of high-precision positioning systems in vehicles, with a projected delivery volume of 4.22 million passenger cars in China from January to October 2025, representing a year-on-year growth of 181% and a penetration rate of 22% [1][6]. Group 1: Market Dynamics - Domestic automakers are adopting a multi-source fusion positioning strategy that combines high-precision positioning, auxiliary driving maps, and vehicle-end sensors, primarily utilizing IMU+GNSS+RTK solutions [1][6]. - The core technology foundation for high-precision positioning is the complementary collaboration between GNSS+RTK and IMU, with the localization and controllability of IMU chips determining the supply chain security of high-precision positioning solutions [7]. Group 2: Competitive Landscape - The domestic market for automotive-grade MEMS IMU chips has historically been dominated by companies like ST, Bosch, TDK, and Murata, but recent years have seen significant breakthroughs by local manufacturers [7]. - Duyuan Technology's self-developed 6-axis automotive-grade GST80 MEMS IMU sensor chip has filled the market gap for domestically controllable MEMS inertial measurement chips and has passed the AEC-Q100 reliability test, confirming its compliance with international automotive standards [2][7]. Group 3: Market Share and Positioning - As of January to October 2025, Duyuan Technology holds a dominant position in the domestic automotive high-precision positioning market with a market share of 59.75%, followed by Huawei and Huace Navigation with 14.51% and 8.01% respectively [2][8]. - Duyuan Technology has established a comprehensive R&D and manufacturing system across the entire industry chain, from chips to modules and solutions, and has successfully integrated its high-precision positioning products into numerous vehicle models from brands like BYD, Li Auto, and Geely [3][8]. Group 4: Future Prospects - With the recent issuance of access permits for L3-level autonomous driving vehicles in China, Duyuan Technology is positioned to be the first company to enable both domestic and international L3-level autonomous driving applications with its high-precision positioning systems [3][8].
