an error during test to your advantage

Everybody knows the Monopoly card  “a failure of the bank to your advantage, you receive…..”

An error that occurred during the vibration testing of our BiSon74-ET-RH sensors feels a bit like that.

Although the sensors were programmed to be tested to very significant levels (1g^2/Hz totalling 38.9g) it has now been confirmed that there was an error in the piloting channel that led to much higher test levels (as can be seen in the accompanying graph.

This plot (taken by the control accelerometer in Y axis) shows an integrated level of 58.77g and a spectral density which is more like 2g^2/Hz.

Although we would never have asked for such high levels of testing ourselves, it feels like an advantage to have done so, knowing that the sensors have survived.

ESA Director General J.Wörner visits Lens R&D

Lens R&D 3 enhOn Wednesday 20th of January 2016,  mr Jan Wörner, Director General of ESA (accompanied by several other ESA representatives as well as  representatives of the ministry of Economic affairs and our national space agency NSO) visited the new optics lab of Lens R&D.

A short company introduction, (explaining the background of our sunsensors, the importance of space and the ESA business incubation program for terrestrial applications and our plans for the future) was followed by a short but very interesting discussion.

Hopefully Mr. Wörner has enjoyed the visit as much as we did.
