Evaluation of a covariance-based clock and ephemeris error bounding algorithm for SBAS
Evaluation covariance-based clock ephemeris error bounding algorithm SBAS
2015/6/24
The largest source of error uncertainty in current Space-based Augmentation Systems, which are single frequency (L1), is the ionospheric delay. In the coming years, the deployment of new signals in L5...
Multiple Gate Delay Tracking Structures for GNSS Signals and Their Evaluation with Simulink, SystemC, and VHDL
Multiple Gate Delay Tracking Structures GNSS Signals Simulink SystemC VHDL
2009/9/3
Accurate delay tracking in multipath environments is one of the prerequisites of modern GNSS receivers. Several solutions have been proposed in the literature, both feedback and feedforward. However, ...
