The target improvement forGEO-Ground optical communication links is to increase the usable spatial coverage of the GEO satellite by a factor of two.Description: To date, numerous optical satellite communication links have beensuccessfully demonstrated. Most of these experiments have operated at elevationangles exceeding 25 degrees to overcome significantatmospheric propagation challenges, such as intense turbulence. However, for LEO satellites,about half of their visibility in a circular orbit occurs between 5 and 25 elevation. Therefore, overcoming challenges with low elevation optical links coulddouble operation time. For GEO satellites, the elevation angle remains constant; however, enabling low-elevation links can potentially double thesatellite's spatial coverage on Earth. Moreover, improvements in low-elevation optical links have significant impact on both classical and quantumcommunications.This activity will examine the necessary techniques and develop the required hardware to facilitatelow elevation optical communication links through theatmosphere. This will involve namely: Study the required techniques to enable low elevation links and provide trade-off analysis Design and develop the PAT  fibre-coupled receiver systems of an OGS that enables optical communication links at low elevations Integrate the optical PAT/receiver systems to an identified OGS Perform an experimental link campaign at low elevations Analysis of the obtained results and conclude on a way forward towards higher TRL of the technology developed under this contract.","ecosrequired":false,"establishment":"ESTEC","firstPublicationDate":"2026-03-18T09:01:11","id":183827,"idEra":24788,"initiatingService":"RNC-FQ","ipmeasure":"N/A","isArchived":false,"isCancelled":false,"isReissued":false,"isToBeReissued":false,"issueQuarter":"000","lastUpdateTime":"2026-11-03T08:54:43","lastUpdateUser":"sapancot","openDate":"2026-11-03T08:54:39","priceRange":"> 500 KEURO","programmeReference":"OP - Advanced Techno","tanumber":"1-13367","title":"GROUND STATION FOCAL PLANE ASSEMBLY AND ACQUISITION SYSTEM FOR LOW-ELEVATION OPTICAL COMMUNICATION (ARTES 4.0 SL SPL 6C.087) - EXPRO+","directorate":null,"countries":[{"id":1},{"id":26},{"id":24},{"id":23},{"id":22},{"id":19},{"id":18},{"id":17},{"id":16},{"id":62},{"id":15},{"id":12},{"id":11},{"id":10},{"id":9},{"id":8},{"id":6},{"id":5},{"id":2},{"id":13},{"id":67},{"id":25},{"id":7},{"id":4}],"products":[{"id":40}],"technologies":[{"id":289}],"status":{"id":2},"tenderType":{"id":5},"isFavourite":false,"eraVersion":1,"stageNumber":null,"isNew":false,"isUpdated":false,"declarationOfCompliances":["All the required declarations of compliance have been addressed and included in our proposal&#39;s Cover Letter."],"keyAcceptanceFactors":["The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to satisfy the “Eligibility Requirements” (see section 1.1 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to fulfil the requirements concerning “Free Competition” (see paragraph 10 of the Cover Letter of the Proposal Template);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to accept the conditions established for “Non commitment by the Agency in competitive procurements” (see section 1.7 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to be compliant with the “Non Benefits Requirements” (see section 1.8 of the EXPRO/TC);","The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a binding price;","The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a price type compliant with the one requested in the ITT;","The Tenderer confirms that the tender is compliant with the budgetary limit applicable to the ITT;","The Tenderer confirms that: supporting evidence of the authorisation of funding from the relevant Participating State(s) is provided as part of the Tender cover letter and in accordance with the requirements of section 4 of the Cover letter to the present ITT."],"evaluationCriterias":[{"criterion":"Background and experience (related to the particular field concerned) of the company(ies) and staff, including adequacy of proposed facilities.","weightingFactor":"40%"},{"criterion":"Understanding of the objectives of the activity and discussion of problem areas, and adequacy of the programme of work.","weightingFactor":"40%"},{"criterion":"Adequacy of time dedication and costing, compliance with administrative tender conditions and acceptance of the contract conditions.","weightingFactor":"20%"}],"entities":[],"procurementProposal":null,"responsible":"Giusy Menghini","updateReason":"Tender Action Issued"}],"totalNew":0,"totalUpdated":0}
