White Rabbit based Time Distribution System

Beskrivning

EISCAT Scientific Association is conducting a project with the goal to construct a new radar system, EISCAT_3D, which will be a next generation incoherent scatter radar capable of providing 3D monitoring of the atmosphere and ionosphere. EISCAT_3D is primarily designed to investigate how the Earth's atmosphere is coupled to space, and the system will be a multi-static radar composed of multiple phased-array antenna sites containing crossed dipole antenna elements. The radar sites will be located in Finland, Norway and Sweden. The Time Distribution System for EISCAT_3D will comprise of network switches following the White Rabbit Precision Time Protocol Core (WRPC), an Ethernet-based hierarchical master-slave architecture for clock distribution including compensation for any latencies in transmission lines and electronics within the network. The WRPC hardware, gateware, and software is entirely based on open-source designs.
