Analysis of combined frequency drift and offset for Galileo/GPS single shot receiver architectures
International Symposium on Signals, Systems and Electronics, 2007-7-30 ~ 2007-8-2, pp 575-578, 2007
This paper analyzes the combined effect of a residual frequency offset and drift after down-conversion for single shot receiver architectures as they are currently utilized in mobile terminals for GPS reception. The change in the receiver detection probability due to this effect is calculated, as well as the associated connected sensitivity-loss. The obtained results are given for the GPS C/A code and open Galileo signal, both in the L1 band.
