This session will cover instrumentation and measurement techniques for all aspects of space borne scientific sensors. The intention is to encourage a discussion between instrument scientists/engineers across the fields on one hand and between these people and the data exploiting scientists on the other hand. We welcome contributions discussing new ideas and enabling technologies as well as reviews and presentations of instruments already in space or near launch. In addition, generic talks discussing design principles, miniaturisation, shared use of subsystems, component selection, instrument calibration etc. are most appreciated.
