Descripción
In recent years, spacial agencies have shown a growing interest in optical wireless as an alternative to wired and radio-frequency communications [ 1, 2]. The use of these techniques for intra-spacecraft communications reduces the effect of take-off acceleration and vibrations on the systems by avoiding the need for rugged connectors and provides a significant mass reduction. Diffuse transmission also eases the design process as terminals can be placed almost anywhere without a tight planification to ensure the proper system behaviour. Previous studies [3, 4] have compared the performance of radio-frequency and infrared optical communications. In an intra-satellite environment optical techniques help reduce EM! related problems, and their main disadvantages - multipath dispersion and the need for line-of-sight - can be neglected due to the reduced cavity size. Channel studies [5] demonstrate that the effect of the channel can be neglected in small environments if data bandwidth is lower than some hundreds of MHz.
