Deliverable 5.1: Software Interface Control Documents

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).

EISCAT_3D, the new Arctic radar for space weather research gets go-ahead for construction

Press Release

EISCAT_3D, the new Arctic radar for space weather research gets go-ahead for construction

A new international research radar called EISCAT_3D was given the green light to proceed this month, promising a step-change in understanding the effect of solar storms and space weather on the upper atmosphere in the Arctic, including the magnificent Northern Lights. At a total cost of 685 million Swedish crowns, the EISCAT_3D facility will be distributed across three sites in Northern Scandinavia - in Skibotn, Norway, near Kiruna in Sweden, and near Kaaresuvanto in Finland. Each site will consist of about 10.000 antennas fed by a powerful 5 MW transmitter at Skibotn and a receiver at each of the three sites. The EISCAT_3D project will start in September 2017 with site preparations to begin in summer 2018. The radar is expected to be operational in 2021.

EISCAT_3D will be the world’s leading facility of its kind, offering a critically important window to the upper atmosphere and the near-Earth space in the European Arctic. The system will be built by the EISCAT Scientific Association, primarily comprising research councils and national institutes from Finland, Norway, Sweden, the United Kingdom, Japan and China, with additional members from several other countries. EISCAT_3D is the culmination of a 10-year design and preparation phase, supported by the European Union. The selected design is a sophisticated phased-array radar which brings together new capabilities never before combined in a single instrument. As the name suggests, a key capability is to measure a 3-D volume of the upper atmosphere, in unprecedented detail. This is necessary to understand how energetic particles and electrical currents from space affect both the upper and the lower atmosphere (e.g. space weather and auroral phenomena) as well as man-made technologies such as satellites and power grids on the ground.

Dr Craig Heinselman, EISCAT Director says,

“We are very excited to be starting construction of the new EISCAT_3D radar system. Building on over three and a half decades of scientific observations with the legacy EISCAT radars, this new multi-site phased-array radar will allow our international user community to investigate important questions about the physics of the near-Earth space environment. The radar will make measurements at least ten times faster and with ten times finer resolution than current systems. It will also provide fundamentally different measurements which are unique in the scientific world by utilizing, initially, fully flexible receive arrays at two separated locations in the Nordic region in concert with the core transmit/receive array. These systems will let us probe phenomena such as the aurora borealis in three dimensions and, in concert with a variety of other measurements, will allow us to uncover the fundamental effects of phenomena such as space weather. EISCAT_3D uses modern analog and digital technologies that enable flexibility now and a path forward for implementing new ideas that emerge from future discoveries. It truly represents a platform for the next generation of space scientists to build upon.”

Background Notes:


The EISCAT Scientific Association,, provides state-of-the-art instrumentation to scientists in its associated countries for investigations into the upper atmosphere and ionosphere above northern Scandinavia. The EISCAT radars can be found in both mainland Norway, Finland, and Sweden and on Svalbard. EISCAT has supported scientific investigations since 1981 and continues to provide top quality instruments and data products to researchers from around the globe. Areas of specialization include quantifying the effects of Space Weather on Earth’s upper atmosphere, understanding the basic mechanisms of the formation and activity of the aurora borealis, and looking for long-term trends in the ionospheric response to effects on the sun and in the solar wind.

Deliverable 4.1: First report on industry contracts

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.

Milestone 3: Contracts signed with vendors

Under EISCAT3D_PfP, the contracts for procurement of major sub-systems are signed.

The First Stage Receiver Unit (FSRU) contract was signed with National Instruments, Sweden on 2016-11-03 and the Antenna Unit (AU) contract was signed with Huber+Suhner Ltd, UK on 2016-12-13.

Thus, Milestone 3 in the EISCAT3D_PfP project was reached on 13 December 2016.
