Optical satellite-to-ground links, such as those planned for ESA's OpSTAR mission, are vulnerable to atmospheric effects, particularly cloud cover, which can degrade or completely interrupt communications with an Optical Ground Station (OGS). The study will assess and experimentally demonstrate atmospheric transmission enhancement techniques designed to improve link availability under adverse weather conditions. It will evaluate whether these approaches can maintain accurate and reliable timing and ranging measurements between laser terminals representative of future operational optical PNT systems.","ecosrequired":true,"establishment":"ESTEC","firstPublicationDate":"2026-09-24T17:39:51","id":195605,"idEra":25732,"initiatingService":"RNC-FNI","ipmeasure":"N/A","isArchived":false,"isCancelled":false,"isReissued":false,"isToBeReissued":false,"issueQuarter":"264","lastUpdateTime":"2026-11-03T13:33:23","lastUpdateUser":"ltena","openDate":"2026-10-16T10:21:47","priceRange":"> 500 KEURO","programmeReference":"NAVISP EL1","tanumber":"1-13718","title":"NAVISP EL1-134 ALL-WEATHER LASER TIMING AND RANGING LINKS FOR OPTICAL PNT SYSTEMS - EXPRO+","directorate":null,"countries":[{"id":1},{"id":168},{"id":67},{"id":26},{"id":24},{"id":23},{"id":16},{"id":22},{"id":13},{"id":12},{"id":11},{"id":9},{"id":6},{"id":2},{"id":15}],"products":[{"id":23},{"id":294},{"id":386}],"technologies":[{"id":240},{"id":298}],"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'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 a statement is attached to the Cover Letter, signed by the Delegate(s) representing the country/ies in which the Prime Contractor (and if applicable its subcontractors) reside(s), authorising the Agency to fund the quoted price from their contribution to NAVISP Element 1 programme; in the case where the national legislation provides otherwise (e.g. Greece) a positive statement for availability of funds under NAVISP Element 1 shall be included in their proposal.\n"],"evaluationCriterias":[{"criterion":"Background and experience (general and related to the particular field concerned) of the company(ies) and staff, including adequacy of proposed facilities.","weightingFactor":"35%"},{"criterion":"Understanding of the requirements and objectives and discussion of problem areas, and adequacy of the programme of work.","weightingFactor":"50%"},{"criterion":"Adequacy of time dedication, management and costing, compliance with administrative tender conditions and acceptance of the contract conditions.","weightingFactor":"15%"}],"entities":[],"procurementProposal":null,"responsible":"Maria Papaioannou","updateReason":"Tender Clarification has been published"}],"totalNew":0,"totalUpdated":0}
