Dual-Frequency Smoothing for CAT III LAAS:Performance Assessment Considering Ionosphere Anomalies
Dual-Frequency Smoothing CAT III LAAS Considering Ionosphere
2015/6/25
Strong ionosphere storms are the most-threatening potential fault mode for the Local Area Augmentation System (LAAS). Multi-frequency GPS techniques are known to be an effective means of reducing or r...
Validation of Multiple Hypothesis RAIM Algorithm Using Dual-frequency GNSS Signals
RAIM Algorithm Dual-frequency GNSS Signals
2015/6/25
A Multiple Hypothesis Solution Separation (MHSS) RAIM algorithm was developed at Stanford in recent years, with the purpose of meeting the stringent integrity requirements imposed by the Federal Aviat...
In the next few years GPS will start broadcasting civil signals suitable for aviation use on both the L1 and L5 frequencies. In addition, Galileo and other constellations will offer an even greater nu...
Signal Deformation Monitoring for Dual-Frequency WAAS
Signal Deformation Monitoring Dual-Frequency WAAS
2015/6/24
Previous signal deformation analyses and monitor designs have primarily focused only on threats to the L1 C/A code. They have traditionally relied on a combination of empirical measurements and analyt...
