Abstract In this paper, the data wipe-off (DWO) algorithm is incorporated
into the vector tracking loop of the Global Positioning System (GPS) receiver
for improving signal tracking performance. The navigation data, which contains information that is necessary to perform navigation computations, are
binary phase-shift keying (BPSK) modulated onto the GPS carrier phase with
the bit duration of 20 ms (i.e., 50 bits per second). To continuously track the
satellite’s signal in weak signal environment, the DWO algorithm on the basis
of pre-detection method is adopted to detect data bit sign reversal every 20
ms. Tracking accuracy of a weak GPS signal… More >
