Description

Defence Equipment and Support (DE&S), on behalf of the Ministry of Defence (MOD), has published a UK 1 Notice purely for information purposes. The Authority would now like to engage with the market via this UK2 Notice and the Defence Sourcing Portal (DSP) opportunity listing, which can be found here: https://contracts.mod.uk/esop/guest/go/opportunity/detail?opportunityId=60844. This Space Capability Project, designated 'NOCTIS-2', comprises a novel space surveillance approach utilising an optical array, and potentially, an Infra-Red (IR) telescope. The project encompasses the procurement, installation, and through-life support of the system. The purpose is to monitor satellites in all Earth-centred orbits, including Low Earth Orbit (LEO) and Geostationary Orbit (GEO) in order to enhance the UK’s sovereign SDA capabilities. The capability is required to operate in Surveillance & Tracking modes in order to provide a persistent stare capability of the GEO Belt and tessellate across as wide a Field of View as possible whilst also providing a more exquisite capability that can contribute to object characterisation. Project 'NOCTIS-2' will be executed at a location outside the UK. The Procurement Specific Questionnaire (PSQ) is expected to be released in Quarter 1 of 26/27 FY.
