This Periodic Report is the second and final periodic report of the EISCAT3D_PfP project. It covers the months 13 to 24 of the 2-year project. The report addresses the progress of the project during its second year of activities.
This report includes documents used for the procurement of three of the critical components under the EISCAT3D_PfP project. They have been updated following the experiences gained from the implementation of the Test Subarray. The additional requirements needed to procure these components for the full EISCAT_3D implementation have not been considered.The documents included are:
- The Enquiry letter. This is the introduction to a tender opportunity. The Enquiry also indicates the expected contractual requirements for the awarded contractor.
- The Technical Specification for each of the sub-systems identified as critical EISCAT_3D components, updated based on the findings from the project:
- First Stage Receiver Unit (FSRU)
- Antenna Unit (AU)
- Pulse and Steering Control Unit (PSCU)
- The System and Subsystem Design Description, also updated based on the findings from the project
Each enquiry also includes a Statement of Work, a Contract Data Requirements List and a Requirements Answer template. These three documents have, for this report, been simplified to just show their general structure.
The purpose of this document is to report the test and buildup of the PfP Test Subarray, which contains the logical components Instrument Container, Antenna Unit, First stage Receiver Unit, Pulse and steering Control unit, Power Supplies, Sub System Manager and Time and frequency Unit.This is Deliverable 6.1 of the EISCAT3D_PfP project.
The opening event for the construction of the first stage of the EISCAT_3D system took place in Tromsø and Storfjord on 7 September 2017. In connection to this event, a workshop with presentations of different aspects of the future facilities was held the day before and the day after the main event.

Deliverable 2.2 in the EISCAT3D_PfP project contains the test plan for each of the subsystems and for the overall sub-array, which is planned to be constructed at Ramfjordmoen site in Norway. Further, this report will serve as guideline for the testing of test sub-array and also, to assess the interoperability of the various subsystems.
The electronic hardware for the Test Array arrived on the test site at Ramfjordmoen, Norway, in the beginning of July 2017.
This is the second report that discusses the progress of industry contracts for the procurement of production-ready designs and hardware of various sub-systems of the test sub-array. This test subarray will be built and tested at the existing EISCAT site in Ramfjordmoen, Norway by the end of EISCAT3D_PfP project in August 2017. This report discusses the progress of the procurement of the following sub-systems:
- First stage receiver unit (FSRU)
- Antenna unit (AU)
- Pulse and steering control unit (PSCU)
- Time and frequency unit
- Status and control unit
- Cables, connectors and containers
Further, this report also includes information about the Transmit unit (solid state power amplifier and power supply units) which are delivered as an in-kind contribution from National Institute of Polar Research (NIPR), Japan.
The antenna elements, containers and other site structural elements arrived on the test site on 12 June 2017.
This report discusses key aspects of the Sub-Array Controller (SAC), which performs software control and monitoring for the PfP test sub-array. The report places the SAC software into the context of the planned control system of the full EIESCAT_3D system. The EISCAT_3D radar control system will be comprised of approximately 100 stand-alone, identical SACs, orchestrated in star-like configuration by a top level EISCAT Real-time Operating System (EROS). The E3D EROS is a direct descendent of the EROS that is presently running all other EISCAT radars. The required high time resolution system-wide synchronization to sub-nanosecond accuracy is accomplished via the White Rabbit time-and-frequency system developed at CERN. A key software component of the control system is the EISCAT Shell module (ESH).
