Comparative study on joint data/pilot strategies for high sensitivity Galileo E1 open service signal acquisition

High Sensitivity Techniques for GNSS Signal Acquisition

“…Therefore, if the acquisition is performed on both channels, then the better sensitivity improvement can be obtained. In literature, (Mattos, 2005;Ta et al, 2010) use this approach for Galileo E1 OS signal acquisition.…”

“…However, SC also implies a waste of half of the real capability. Therefore, joint data/pilot acquisition strategies are introduced to utilize the full potential of the E1 OS signal (Mattos, 2005;Ta et al, 2010). In the followings, these strategies are described together with the performance evaluation.…”

“…Galileo E1 OS, E5, E6; GPS L5, L2C, L1C). These facts yield another approach, usually named channel combining acquisition (Gernot et al, 2008;Mattos, 2005;Ta et al, 2010) able to fully exploit the potential of modern navigation signals for sake of sensitivity improvement.…”

A novel signal acquisition method for GPS dual-frequency L1 C/A and L2C receivers

“…As introduced in [6], [7], the conventional acquisition process strives to determine the presence of a desired signal, defined by PRN code (e), code delay (e) and Doppler offset (fd), in the incoming signal. The uncertainty regions of (e, e, fd) form a signal search-space, each cell (c, 0, id) of which is used to locally generate an equivalent tentative signal.…”

A robust acquisition architecture for GPS safety-of-life L5 Signal

“…The work in [6] proved the advantages of leveraging both channels simultaneously for acquisition purposes of the Galileo E1 signal. However, the differences in the code structure, multiplexing mechanism, signal bandwidth of the two signals should be considered when applying this approach for the L5 signal.…”
