eiscat_3d-logo-green-250pxEISCAT3D is going into implementation phase. The final product is a new system which will be a next generation incoherent scatter radar capable of providing 3D vector monitoring of the atmosphere and ionosphere.

Stage 1 of the EISCAT_3D implementation shall comprise three sites in northern Norway, Finland, and Sweden. Each site has a a 70-80m diameter antenna array with 9919 dual-polarization antenna elements organized into 109 subarrays of 91 elements each. The Norway site will also have an additional 10 subarrays, located separate from the main antenna array.

In addition to the antenna elements, the sites will also have support structures, beamformers, receivers, transmitters and other subsystems for control, time-keeping et cetera. Active RF components are placed into Subarray Containers which are placed under the Array Structure. For each site, there shall be 109 Containers with electrical installation and racks pre-installed.

Tender 1: Antenna Unit (CLOSED)

Tender 2: First Stage Receiver Unit (OPEN: EOI phase)

The FSRU procurement covers the low noise amplifier, analogue-to-digital converter and the first stage beamformer system receiver chain for each of the E3D antennas at the three sites. Since each E3D antenna receive in two polarisations, the total number of receive channels is 19 838 for a fully deployed site. Due to potential funding constraints, a part of system build-up will be handled as options that may be ordered later, but before the final regular deliveries are done.

Illustration E3DS1 FSRU

The EISCAT_3D system will be built as sub-arrays with 91 antennas in each block. The system should integrate the resulting 182 receive channels (for each 91-antenna sub-array) in a common FSRU unit.

The procurement will be through a two-stage process: first an open competitive procedure followed by restricted (invited only) tendering. To be part of this process, tenderers need to first express their interest:
