The article describes the hardware architecture of computational units for the construction of GLONASS / GPS navigation user equipment. The described possible route to improve of some architectures based on field programmable gate arrays (FPGAs).
The following paper discusses a conducted synthesis and assessment of the effectiveness of control algorithms for null formation in the radiation pattern of a flat phased antenna array according to two coordinates; the procedure is performed by adjusting the amplitude distribution in rows and columns.
Considered hardware-software system for research characteristics of noise immunity and accuracy GNSS receiver implemented on the basis of National Instruments hardware platform and programming environment LabView. The complex provides a simulation of the navigation field and the source of interference, the analysis of the received signals, the determination of measurement error of navigation parameters...
