Research on Broadband RF Chip for High-Precision GNSS Application

摘要

Satellite navigation system concerns the national economy and people's livelihood. Especially, the applications of high-precision GNSS have an increasingly important impact on people's daily life. High-precision GNSS devices not only provide higher measurement accuracy of satellite navigation signals, but also need to support differential correction, precision ephemeris, and high-precision processing algorithms. That means that high-precision GNSS applications face with higher technical threshold, compared with mass consumer applications. For the high-precision applications, broadband RF chip is an important part of high-precision OEM board, which determines the performance of high-precision OEM board.
