Cross-Band Aided Code Acquisition in Dual-Band GNSS Receivers

The problem of fast code acquisition in dual-band Galileo
\nreceivers is tackled. The proposed techniques exploit the Galileo
\nE1 and E5 Open Service signals structure, implementing a
\ncross-band aiding approach that yields mutual assistance in
\ncode synchronization adopting a master/slave configuration.
\nThe schemes are analyzed in terms of mean acquisition time
\n(MAT) introducing the procedure flow-graph and overall mean
\nacquisition time (OMAT). Numerical evaluation shows enhanced
\nOMAT performance w.r.t. autonomous dual-band acquisition,
\nguaranteeing complexity reduction.
