    • Delivery with a smile

      A couple of minutes ago DHL picked up the BiSon64-ET-B Sunsensors intended for the Luxspace SAT-AIS ESAIL mission.

      The delivery marks the end of en era for Lens R&D as it was actually the first flight project acquired back in 2015. Over this Artes21 program we managed to increase our experience as well as the qualification status of our products drastically and as such we are very grateful to Luxspace for selecting the BiSon64 Sunsensors well before the flight qualification was finished.
      We are looking back upon a very open and positive cooperation and hope to continue cooperating for many years to come.

      As all good things come to an end we would like to thank the Luxspace team, the team at ESA and our national space agency NSO for the support over the past number of years. We are eagerly awaiting the launch and first flight results and wish Luxspace lots of succes also with future projects.

    • BiSon64-B units on ESAIL

      It is always nice to see our sensors projected on satellites that are actually being build.

      If you look carefully you can find five out of 6 BiSon64-B units that will be mounted on the Luxspace satellite called ESAIL.
      This mission is based on the new Luxspace platform called Triton2 for which more information can be found on the luxspace website: https://luxspace.lu/triton-2/

      Although the above picture is only a CAD drawing, the actual satellite is nearing completion and launch is projected for Q2/2019. Our BiSon sunsensors actually achieved a significant level of qualification through the related ESA Artes21 program  SAT-AIS and we are proud to finally see this platform accepted by ESA and ready for flight.

    • Congratulations to the spot-on team

      Last Friday 26th of October, the team of students that designed and manufactured the spot-on tests setup have received two rewards (each worth 2500 Euro) during the annual NLF gala. They received both the Jan Dullaert price for the best subject and the André Kuypers price for the best space related project. The latter was handed over by the Dutch astronaut André Kuypers himself.

      During a short discussion after the reward ceremony it became clear that the price was granted because of the excellent quality of work delivered and the craftmanship exhibited by the instrument builders trained at the Leidse instrumentmakers school (Instrument builders school of Leiden LIS).

      4 years of intensive training and practical work have payed off for these young professionals in the sense that they have shown to be able to not only study and design, but also build a complicated precision setup intended to measure the temperature coefficient of BiSon64-ET sunsensors in vacuum over a temperature range of -125°C to +125°C. Due to this wide temperature range and the desire to test as many sensors as possible in a single go (to save time and money) a highly specialized setup was needed which is vacuum compatible, has a low thermal mass and a high thermal conductivity. very challenging requirements which have been met by means of a technically sophisticated solution.

      At Lens R&D we are proud of their success and happy with the project results.
