Abstract
In this paper, the effect of interferences on the GPS weak signal is analyzed by the carrier
to noise ratio(C/No) which is the ratio of the received carrier power level to the noise power level in a
1Hz unit. The C/No is an important parameter describing the performance of a GPS receiver and an
indicator of the quality of the received signal. To receive the GPS weak signal, adaptive acquisition
method using differential coherent integration is implemented to the software GPS receiver and FLL
discriminator is applied to the signal tracking loop. The proposed algorithm is verified by simulation,
and the effect of the interference on signal is provided by theoretical results of the carrier to noise
ratio.
