Normalized GNSS Interference Pattern Technique for Altimetry
It is well known that reflected signals from Global Navigation Satellite Systems (GNSS) can be used for altimetry applications, such as monitoring of water levels and determining snow height. Due to the interference of these reflected signals and the motion of satellites in space, the signal-to-noise ratio (SNR) measured at the receiver slowly oscillates. The oscillation rate is proportional to...
متن کاملA Real-Time Interference Monitoring Technique for GNSS Based on a Twin Support Vector Machine Method
Interferences can severely degrade the performance of Global Navigation Satellite System (GNSS) receivers. As the first step of GNSS any anti-interference measures, interference monitoring for GNSS is extremely essential and necessary. Since interference monitoring can be considered as a classification problem, a real-time interference monitoring technique based on Twin Support Vector Machine (...
متن کاملDerivation of the Cramér-Rao Bound in the GNSS-Reflectometry Context for Static, Ground-Based Receivers in Scenarios with Coherent Reflection
The use of the reflected Global Navigation Satellite Systems' (GNSS) signals in Earth observation applications, referred to as GNSS reflectometry (GNSS-R), has been already studied for more than two decades. However, the estimation precision that can be achieved by GNSS-R sensors in some particular scenarios is still not fully understood yet. In an effort to partially fill this gap, in this pap...
متن کاملEstimation of Adaptive Antenna Induced Phase Biases in Global Navigation Satellite Systems Receiver Measurements
It is well known that an antenna can introduce direction dependent biases into the code and carrier phase measurements of Global Navigation Satellite System (GNSS) receivers. If the antenna has a fixed pattern, these biases can be calibrated and corrected. However, the pattern of an adaptive antenna changes based on the incident signals and, as a result, so do its bias errors. In this thesis, w...
