研究目的
The objective is the minimization of interferences and multipath effects, ultimately enhancing the availability, accuracy and reliability of GNSS receivers.
研究成果
Controlled radiation pattern antennas constitute a powerful tool for multipath and interference rejection, thus increasing the accuracy, availability and reliability of the GNSS receiver. Depending on the information available at the antenna and the computational power, several receiver array architectures and signal processing techniques are possible. The article concludes with some configuration examples, including experimental results using a specific implementation on a prototype.
研究不足
The paper discusses the challenges in deploying practical systems, including the impact of implementation issues on final performance, such as antenna phase center biases, calibration requirements, and computational load for online calculation of the covariance matrix inverse.
