Abstract

To adapt to the development trend of global navigation satellite system(GNSS) receiver

a new correlation algorithm is studied

which can acquire the multiple GNSS signals and can be used in the software receiver.The algorithm can acquire and process the open signals transmitted on L1 frequency band from GPS and Galileo systems.Through the simulation

the main factor affecting the performance of the algorithm is analyzed

and the results of acquiring the civil signals are given.The simulation results show the algorithm can acquire the GNSS signals quickly.It is simple

flexible and convenient and the conclusion will direct the design of software GNSS receiver.
