Abstract
Today's spacecraft employ hundreds of sensors. With spacecraft becoming increasingly complex, there is the need for spaceborne measurement systems that are of low mass and volume, yet of high reliability and lifetime in the harsh space environment. Targeted towards future applications in telecommunication satellites, the presented FOSAT project aimes at a corresponding fiber-optic measurement system demonstrator. This goal particularly calls for a vast number of sensors being multiplexed, enabling systems with a minuscle per-sensor mass, volume and power share. To achieve this, several multiplexing techniques are jointly applied in the presented project to form hybrid multiplexing. Furthermore, an interrogation technique which allows a dynamically adaptable tradeoff between the number of sampled sensors and the sampling rate is employed to increase operational flexibility. The design and the implementation of this unit are presented and a test result is summarized.
