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 (CLOSED)
Tender 3: Sub-Array Transmitter System (CLOSED)
Tender 4: Pulse and Steering Control Unit (CLOSED)
Tender 5: Site constructions: Buildings (REOPENED)
Update 29 April 2020: The previous tendering of the buildings for the three EISCAT_3D sites did not attract any bids. The procurement objective has been updated and is now reopened. The tendering will be done in two phases, first an expression of interest including a possibility to influence the process followed by the full tender. First deadline: 22 May 2020
