GPS Synchronisation for FPGA Devices

This article deals with methods research for synchronization pulses utilization provided by some GPS units for measurement synchronization. Initially there are problems of GPS described. Further there are drawn out realized prototypes of measurement systems based on microcontrollers where is expected milliseconds measurement accuracy followed by description GPS synchronized time source implementation in logic gate arrays (FPGA), which allows accurate measurement of microseconds and better. This article describes the theoretical premises and selected measured properties of realized solutions. In conclusion there are prepared experiments described which should be realized during research of this issue.
