Estimation of ICAO Threat Model Parameters For Operational GPS Satellites
Estimation ICAO Threat Model Parameters GPS Satellites
2015/6/26
The ICAO Second Order Step threat model defines a class of signal deformations that present a potential integrity threat to GPS-based aircraft landing systems such as the Local Area Augmentation...
Signal Deformations On Nominally Healthy GPS Satellites
Signal Deformations Nominally Healthy GPS Satellites
2015/6/26
This paper describes the collection and analysis of real data from twenty-four current, nominally healthy GPS satellites in the context of the ICAO second-order step (2OS) fault model.
Alternative Characterization of Analog Signal Deformation for GNSS‐GPS Satellites
Analog Signal Deformation GNSS‐GPS Satellites
2015/6/24
Currently, analog signal deformation is described using individual-chip step response curves for each GPS/WAAS-GEO satellite. Such a set of curves is helpful– it allows us to have an overall idea of t...
