Summary of information related to WP4

September 7, 2015
Work Package 4 will procure, from industry, designs that are as close to final as possible. The procurement activities will be coordinated with Work Package 2 that develops iteration of the subsystem designs with considerations toward manufacturability, serviceability, reliability, energy efficiency, and cost. A primary goal is to move from the single-unit prototyping and design that was completed under the Preparatory Phase project toward a design that can be efficiently produced in a mass-production environment. This will include having industry perform all appropriate design-rule checks, ensure that electronics assemblies can be manufactured using modern, automated technologies, and ensuring that the resulting designs can be serviced and maintained in a cost effective manner over a multiple-decade time horizon. This work package includes the work procured from industry and the project office activities that are directly related to monitoring the industry contracts.

The other major coordination efforts for this work package are covered by Work Package 1 and Work Package 2.

The subsystem designs to be procured are as follows:

  • Antenna element
  • Sub-array structure
  • Instrument container (including environmental controls)
  • Front-end electronics
  • Sub-array beam former electronics
  • Pulse and steering control
  • Ancillary components and subsystems
    • Health and status monitoring and control
    • Timing distribution
    • Cables/interconnects

These subsystems will be procured, initially, as first articles for inspection and individual performance testing. Once the designs have been vetted, a sufficient number of units will be procured to populate the 91-element Test Subarray. This Test Subarray will be assembled and tested in Work Package 6.

Activities in this work package include

  • Site preparation design
  • Antenna element design
  • Support structure design
  • Instrument container design
  • Front end design
  • Beam former design
  • Pulse and steering control design

Deliverables

Deliverable 4.1: First report on industry contracts

February 2, 2017
This report focuses on 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 sub-array will be built and tested at the existing EISCAT site in Ramfjordmoen, Norway by the end of EISCAT3D_PfP project. 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 will be delivered as an in-kind contribution from National Institute of Polar Research (NIPR), Japan.

Deliverable 4.2: Second report on industry contracts

August 8, 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.
