专利汇可以提供MULTI-GNSS SIGNAL PROCESSING WITH CLOCK-DIFFERENCE MODELING专利检索,专利查询,专利分析的服务。并且Three new methods are presented to improve floating solutions and ambiguity resolution for multiple global -satellite navigation systems (GNSS), one of which may be an FDMA-based GNSS such as GLONASS: (1) modeling of the hardware-related differential clock error between two (or more) different GNSS, (2) modeling the frequency-dependent biases present in frequency-division multiple access (FDMA) GNSS, and (3) an ambiguity resolution method called Scoreboard Partial Fixing (SPF). The methods presented are independent of the number of carrier frequencies tracked for each satellite navigation system. Their application results in quicker and more reliable ambiguity resolution. The benefits of combining observations of multiple GNSS are exploited in a very efficient way, in contrast to known algorithms which often result in degraded performance with multiple GNSS. The frequency-dependent bias method has been found effective with GNSS observations from a combination of substantially dissimilar hardware, e.g., for processing signals from GNSS receivers of different manufacturers.,下面是MULTI-GNSS SIGNAL PROCESSING WITH CLOCK-DIFFERENCE MODELING专利的具体信息内容。
