The Effects of the Ionosphere and C/A Frequency on GPS Signal Shape:Considerations for GNSS-2
Effects Ionosphere C/A Frequency GPS Signal Shape Considerations
2015/6/29
By greatly increasing the chipping rate of the pseudo random noise (prn) code, it may be possible to measure the ionosphere (TEC) in near real time, by exploiting the dispersive nature of the ionosphe...
With the successful implementation of the Wide Area Augmentation System (WAAS) for the North America, there is interest in implementing similar systems in other parts of the world. The ionosphere over...
Ionosphere Threat to LAAS: Updated Model,User Impact,and Mitigations
