The Research of Fast Acquisition Algorithms in GNSS
Recently, GNSS has been applied in various domains deeply and widely. In some of applications such as carbon canyon, GNSS signals degrade severely. The conventional receivers have no ability to deal with such weak signals. The sensitivity performance has already been one of the most important features in modern receivers. Consider the advantages of easy implement and high efficiency, we choose it with coherent integration and differential coherent integration to acquire signals which of power is −145 dBm.
