- Abstract
- The aim of this thesis is to implement a new GNSS interference detection system that extends the functionality of previous systems. This technology will be evaluated on the effectiveness of data collection in GPS L1, GPS L2C and all software changes required to implement it. Additionally there is discussion about extending the technology to log GLONASS L1 and GLONASS L2 data. This thesis is broken up into three sections. First, it describes the current state of GPS ASIC systems, using the SiGe receiver. It covers the reasons that this ASIC requires modernization as well as what behavior the system seeks to emulate. Next, it describes the new hardware that will make up the base of the new system. It covers what each component has been added for and its differences from the previous version. The focus is on the new ability of the receiver to receiver L2C simultaneously with L1 as well as the increased data rate which allows for better positioning. Finally, the thesis describes new software development effort centered around the new system. The thesis describes three test modes used, continuous logging, triggered logging and periodic logging. Extra attention is paid to the implementation of a real time networked version of the code. The final goal of the thesis is to build a low cost distributed system that is capable of detecting and localizing GPS and GLONASS interference on both the L1 and L2 bands.
