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 the distortions for all satellites as well as identify possibly anomalous satellite signals. However, the step response curves do not convey the severity of the distortions to the user in a metric ...

The Marshall Automated Wind (MAW) algorithm for wind determination from geostationary satellite data is described and contrasted with other methods. The major differences between the MAW technique and others are found in the target selection, template size, search area constraints, and in the quality control procedures. Using appropriate data dependent tracking parameters and quality controls, ...

In order to track the carrier phases of Global Navigation Satellite Systems (GNSS) signals in signal degraded environments, a dual antenna joint carrier tracking loop is proposed and evaluated. This proposed tracking loop processes inputs from two antennas, namely the master antenna and the slave antenna. The master antenna captures signals in open-sky environments, while the slave antenna capt...
