PLL Performance for Signals in the Presence of Thermal noise, Phase noise, and Ionospheric Scintillation
Performance of several carrier tracking loops are evaluated by the wideband data that mimic the real ionospheric scintillation. To accommodate the deficiency of the receiver’s oscillator, six-state dynamic model driven by Gaussian-distributed random samples is used to simulate the phase noise inherited by the imperfect crystal unit. Ionospheric scintillation is associated with the deep power fa...
متن کاملGPS Carrier Tracking Loop Performance in the presence of Ionospheric Scintillations
The performance of several GPS carrier tracking loops is evaluated using wideband GPS data recorded during strong ionospheric scintillations. The aim of this study is to determine the loop structures and parameters that enable good phase tracking during the power fades and phase dynamics induced by scintillations. Constant-bandwidth and variable-bandwidth loops are studied using theoretical mod...
متن کاملRobust Tracking Control of Satellite Attitude Using New EKF for Large Rotational Maneuvers
Control of a class of uncertain nonlinear systems, which estimates unavailable state variables, is considered. A new approach for robust tracking control problem of satellite for large rotational maneuvers is presented in this paper. The features of this approach include a strong algorithm to estimate attitude, based on discrete extended Kalman filter combined with a continuous extended Kalman ...

متن کاملModel Analysis on the Performance for an Inertial Aided FLL-Assisted-PLL Carrier- Tracking Loop in the Presence of Ionospheric Scintillation
Ionospheric scintillation has a significant impact on the availability of Global Positioning System (GPS) and Wide Area Augmentation System (WAAS), especially when the GPS/WAAS receiver is dynamically stressed. An example of such a scenario would be an aircraft using WAAS to make an approach and landing. This study investigated the tolerable wideband interference level given various conditions ...
