Abstract: |
This paper analyses the characteristics of multipath signal and the effect on GN
SS(Global Navigation Satellite System) receiver peudo range measurement and carr
ier phase measurement,compares the mulipath suppression methods of GNSS receiver
from two aspects of anti-multipath antenna and baseband signal processing,and p
oints out that by adopting both antenna
technology and baseband signal processing technology at the same t
ime the good suppression result can be achieved for the high-precision GNSS rec
eiver. |
