摘要：Three new methods are presented to improve floating solutions and ambiguityresolution for multiple global satellite navigation systems (GNSS), one of which may bean 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). Themethods presented are independent of the number of carrier frequencies tracked foreach satellite navigation system. Their application results in quicker and more reliableambiguity resolution. The benefits of combining observations of multiple GNSS areexploited in a very efficient way, in contrast to known algorithms which often result indegraded performance with multiple GNSS. The frequency-dependent bias method hasbeen found effective with GNSS observations from a combination of substantiallydissimilar hardware, e.g., for processing signals from GNSS receivers of differentmanufacturers.
