Tenders Are Invited For Battery

Tenders are invited for LISA-ITT-009 Battery The gravitational wave observatory LISA (Laser Interferometer Space Antenna) has been selected as ESAs third large class mission (L-3) within the Cosmic Vision programme. LISAs mission objective is to observe gravitational waves from space in the frequency band of 0.1 mHz to 1 Hz, not accessible from ground-based observatories. The mission architecture consists of a constellation of three spacecraft placed at the vertexes of a near-equilateral triangle with side length of about 2.5 million km (LISA Constellation). An overview of the LISA mission and its objectives can be found on the Agency website here: https://www.esa.int/Science_Exploration/Space_Science/LISA OHB, prime contractor for the programme, has been contracted by the European Space Agency (ESA) for the realization of the LISA programme, building the industrial consortium. The objective of the present procurement is the selection of the subcontractor for the LISA Battery. The battery is part of the LISA Electrical Power Subsystem (EPS). The battery will be rechargeable Li-Ion type battery. This battery will supply the spacecraft with electrical energy when Solar Array power is not available or not sufficient, mainly during launch and transfer phases and during eclipse phases of the satellite. The satellite will be launched with a fully charged battery in order to be able to support the transfer and LEOP scenario until the solar array has been deployed. The procurement of the Battery will be conducted in line with the ESA Best Practices for the Selection of Subcontractors by Prime Contractors in the frame of ESAs Major Procurements. Additional requirements on geo-return may be specified in the ITT data package. Read less Tender Link : https://esastar-publication-ext.sso.esa.int/nonEsaTenderActions/filter/open
