BiSon64-ET and BiSon64-ET-B are coming

Having successfully completed the contract negotiations with ESA, Lens R&D is sure to be able to continue with the development and qualification of the BiSon64-ET and BiSon64-ET-B The foto presented provides an impression of the BiSon64-ET-B as it will be completed and qualified. The underlying GSTP program is quite exciting as it also entails a full qualification according to ECSS standards as well as upgrading the quality control system at Lens R&D to be in line with ECSS standards. The latter means that we will officially enter into the realm of high reliability component suppliers when this program is successfully [...]

Reminder for the Sunsensor Challenge

As it seems a lot of people have missed the invitation, another post of the sunsensor challenge at the AIAA/USU Small Satellite Conference in Utah. Looking forward to a lot of surprising submissions.

Half a degree accuracy, let’s see

For several months now, Lens R&D has been busy building calibrating and analysing a statistically significant number of sunsensors. Based on the results obtained so far, we concluded that all sensors have a common residual error profile. Because this error profile is determining the majority of the errors over the field of view, we decided to investigate the possibility to model this error so that it can be compensated. Based on a thorough analysis of the optical properties of our sensors we concluded that the error profile is related to some of the manufacturing details of our sensors which are [...]

Celebrating the first lustrum at Lens R&D

On Thursday 30th of March a small celebration at the SBIC in Noordwijk marked the 5 year existence of Lens R&D although not very elaborate, the atmosphere was very good and even the weather cooperated in a fantastic manner as it was very sunny and some 8 degrees above the nominal average temperature in March. We especially welcomed the congratulations of Stanley Kennedy and Maureen O’Brian that attended all the way from Colorado USA and mr Franco Ongaro that even came outside the official celebrations because of obligations elsewhere during the party.

Maiden flight for BiSon64 is near

Today, the students from Delft Aerospace Rocket Engineering (DARE) showed the Aether rocket to the public for the first time. 3.3m in length and intended to reach Mach 1.7 before the parachute system is deployed at some 6km height, the rocket is not only a technology demonstrator for the stratos III rocket to be launched later this year (that will try to break the student rocket altitude record) but also contains three BiSon64 sunsensors that will be used to calibrate the on-board gyro’s in real-time and thus avoid rotation of the rocket which could hamper proper parachute deployment. […]

Artes5.2 ITAR free extended temperature sunsensor project final review

After 1.5 years of intensive development and testing we formally came to conclusion of the Artes 5.2 project ITAR free extended temperature sunsensor today by performing a final presentation. Based on inputs gathered from several potential suppliers over the years, the project started as a company internal project some 3 years ago. The main problem these sensors are intended to solve is that for satellites with extendable solar panels, the panels are often blocking part of the sunsensors field of view in the stowed configuration.
