Performance limitations of free-space optical communication satellite networks due to vibrations: Direct-detection digital mode Conference Paper uri icon


  • Free space optical communication between satellites networked together can permit high data rates between different places on earth. The use of optical radiation as a carrier between the satellites permits very narrow beam divergence angles. Due to the narrow beam divergence angle and the large distance between the satellites the pointing from one satellite to another is complicated. The pointing task is further complicated due to vibration of the pointing system caused by tracking noise and mechanical impacts. In this work we derive mathematical performance models for digital direct detection communication satellite networks as a function of the system parameters, the number of satellites, and the vibration amplitude. The optical inter-satellite network model considered includes a transmitter satellite, regenerative satellites, and a receiver satellite all networked together. A …
