Analysis of the Impact of SSR Corrections Update Frequency and Interrupt Time Interval in Real-Time PPP
Abstract In this paper, the effects of SSR corrections of different update frequency on RT-PPP and the interrupt of SSR corrections will be discussed. The effects of this problem on practical applications are analyzed. According to the experiment, if the update frequency of corrections on the service terminal could be controlled within 30 s, it will obtain the accuracy of centimeter-level positioning. If the interrupt of corrections on the client can be controlled within 150 s, it will also obtain the accuracy of centimeter-level positioning, and 200 s will obtain the accuracy of 20 cm and 300 s will obtain the accuracy of decimeter-level.
Key words :
real-time precise point positioning
state space representation
update frequency of corrections
interrupt of corrections
positioning accuracy
