ESA UNCLASSIFIED - For Official Use In relation to the Earth Watch - ALTIUS Element, the European Space Agency is pleased to invite the industries of the participating States - which are currently Belgium, Canada, Luxemburg and Romania - as well as any industries for which there is limited or no known capabilities in the participating states to the: ALTIUS Industry Day which will take place in: ESTEC, Keplerlaan 1, 2201 AZ Noordwijk, The Netherlands on 13 October 2017 starting at 09:00 The ALTIUS mission aims at the development of a limb sounder based on a small satellite. Its main objective is the monitoring of the distribution and evolution of stratospheric ozone at high vertical resolution. Its versatile instrument, which is intended to image the Earth’s limb in the near UV, Visible and Near Infrared spectral regions, in combination with the agility provided by the spacecraft platform may allow measurements of concentration profiles of other species as well as aerosol extinction vertical profiles. Mission lifetime of minimum 3 years is envisaged. ALTIUS is a mission based on an innovative instrument concept and on features offered by an evolution of the PROBA satellite bus. The Industry day will provide a technical and programmatic overview of the ALTIUS mission, covering both Space and Ground Segment. The Agency's plans for the procurement of the Space and Ground Segment will be described and opportunities for industrial involvement will be outlined and discussed during the Industry Day. Participants to the Industry Day will be given the opportunity to present their relevant expertise for ALTIUS to the Agency and Satellite and Instrument Primes and time for discussion will be foreseen. Industries are invited to send a representative(s) to the event. In the event a physical presence can not be assured, the Agency will set up a Visio link and WebEx with the participants who request it. You are invited to inform ESA accordingly of the names of the participants and whether they will attend in person or via Visio/WebEx. The complete agenda for the day will be communicated nearer to the date. Please address any question and communication by email to: Irène Aupetit ([email protected]) and Stephanie Ziegler ([email protected]) If you would like to participate in the Industry Day, please email: Gillian McDonnell ([email protected]) For organisational matters, RSVP by 15 September 2017. .
