Availability is an important index to measure the service performance of navigation satellite.The traditional availability analysis methods only take into a
When a MBOC modulated signal is evaluated by the traditional S-curve bias evaluation method,which exists some problems,such as the selection of correlator s
This paper introduces the work principle and positioning performance of the transponding navigation system,and gives the navigation and positioning measurem
High-quality navigation signal simulator plays an important role as the verifying method for the function and capacity of navigation receivers.With the deve
In the signal structure design of new global navigation satellite system(GNSS),the ideas of secondary/tiered code was introduced.However,due to the inherent
Pseudo-code noise amplification theory of ionosphere-free combination is studied in this article,In allusion to the disadvantage of iono-free combination,Th
In this paper,we presented a method for assessing the broadcast ephemerides accuracy of QZSS by comparing the measured broadcast ephemerides with precise or
