Development, implementation and validation of a real-time Galileo E1-B signal acquisition and tracking scheme

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti, Giuseppe Zamuner, Elham Firouzi

With the introduction of a square wave sub-carrier modulation in the Galileo E1 BOC(1,1) open service signal, the autocorrelation function becomes more complex as compared to the GPS L1 C/A BPSK(1) signal. Indeed, the presence of two secondary side lobes i ...

A Dual-Frequency RF Front-End for Long Antenna-GPS Receiver Links

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Elham Firouzi, Jean-Pierre Aubry

While the Global Positioning System (GPS) is best known for its positioning applications, another way to use GPS is as a time reference for telecommunication networks synchronization. However, as every new communication standard is more demanding, the prec ...

Performance Analysis of Mobile Station Location Using Hybrid GNSS and Cellular Network Measurements

Pierre-André Farine, Cyril Botteron, Elham Firouzi

Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...
