Project description "HYLOC"
The goal of HYLOC is the development and functional validation of a novel multi-antenna GNSS receiver architecture that has similar robustness properties as available high-end receivers. At the same time, due to its much lower complexity, it is associated with huge component cost and space savings as well as low power consumption.
The receiver architecture is designed to provide reliable position, speed and time information in complex radio environments, even in the presence of strong interference signals and multipath propagation. To this end, a new hybrid method is used instead of the purely digital beamforming methods used so far. In the first stage, analog null-steering eliminates sources of interference. In the second, digital stage, the reception beams are directed toward the satellites in order to eliminate multipath signals and other sources of interference.
In the course of basic research, the plan is to develop an initial laboratory prototype of a discrete analog beamformer, which will enable qualitative verification of the application.
