## Description

This procurement describes the activities to be executed and deliverables required by STFC in relation to the definition, supply, and commissioning of a Direct Field Acoustic Noise \(DFAN\) system\. This system will to be used to test satellites and large sub-assemblies in the National Satellite Test Facility\. An acoustic test system is required for the NSTF to permit the testing of any spacecraft up to 7000kg and to fit inside a 4\.6m fairing to the levels and durations required by all the currently available launch systems\. To achieve this, RAL Space intends to purchase a system using the latest commercially available DFAN technology to provide a uniform diffuse sound field to test their customer's satellites and large sub-assemblies\. The use of DFAN technology gives the opportunity to reconfigure the system, add capacity when needed, and be open to future control upgrades and more flight representative test methods\. Please refer to the eSourcing link to access all tender documents\.
