| Abstract: |
| Side-lobe is one of the most important error sources influencing the tracking r
eliability.In order to solve this problem, an improved side-lobes cancellation
technology is proposed. Compared
with traditional technology, this method has good reliability. For the propose o
f minimizing the influence of multipath on the GNSS(Global Navigation Satellite
System), the improved side-lobes
cancellation technology is combined with Narrow Correlator(NC) technology,High R
esolution Correlator(HRC) technology and Early Late Slop(ELS) technology.The
simulations prove that better tracking reliability and accuracy can be achieved
with the improved method. |
