摘要
Abstract
Based on development and industrialization projects of GPS / BD compatible high⁃sensitivity navigation product, the classic carrier tracking loop is modified in this paper to achieve high⁃sensitivity tracking loop. The key idea is to transform the traditional single⁃point integration data into a string data. After FFT transformation of the data,the estimation accuracy of the carrier frequency can be improved,thereby increasing the system tracking sensitivity. The high⁃sensitivity tracking loop is al⁃so analyzed and simulated in this paper to prove its tracking capacity for tracking weak signals.关键词
