Atmospheric Doppler Modelling for Open Loop Tracking in GPS-RO Receivers
Volume 9, Issue 2 , September 2016, , Pages 35-46
Abstract
One of the main challenges of the Open-Loop Signal Tracking method in GPS-RO space receivers, is Doppler prediction. Almost in all satellite communication systems, accurate carrier phase tracking under difficult conditions is depend on Doppler prediction accuracy. Obviously, there are several methods ...

Volume 6, Issue 2 , July 2013, , Pages 21-28
Abstract
In this paper GPS radio occultation has been introduced as a way to extract the electron density of the ionosphere. A GPS radio occultation occurs when a receiver on-board a LEO spacecraft tracks a GPS satellite as it sets or rises through the earth’s atmosphere. The recorded occulted signal phase ...
