Abstract
With all major European primes starting to work on programs >100 satellites in 2015 the time for Space grade Commercial Off The Shelf components has come. For many years there have been discussions on costs savings by offering COTS components and especially the cubesat community knows several vendors that offer space systems in a COTS fashion. None of these component however qualify for the extreme requirements posed by the current constellations under design as most of them have to operate above 1000 km and are preferred to have a 10 to 15 year lifetime. This leads to several megarads of total dose en 15 years at 1400 km will require the ability to withstand some 65.000 thermal cycles. In order to fulfil these requirements full space grade true high reliability components will be needed where on the other hand the financial constraints are very strong.
This is bound to lead to a completely new generation of real high reliability Space grade Commercial Off The Shelf (SCOTS) components. Without knowing these constellations would come, Lens R&D has been focussing on recurring production of true high reliability sensors and now has several sensors in final stage of optimisation which will be offered in a SCOTS approach. The presentation will focus on the mega constellation market, the issues faced when developing SCOTS components and current state of development of our BiSon series of sunsensors.
