摘要: Current GNSS receivers employ independent tracking loop for each received signal, i.e. every satellite and frequency. With this receiver design a time consuming reacquisition is needed, whenever signal temporarily lost. By formulating the process jointly all signals, given involved random processes, such as movements, clock atmospherical effects, spatial spectral correlation of signals can be exploited. The joint method was tested in an airborne during two stages flight. In comparison to commercial shows its great potential by continuously signals. This led us conclusion that joint satellite code carrier makes more robust, especially receivers.
