| 520 | |a To improve performance and reduce the cost of the inter-satellite communication systems, academia and industry are active in discovering adequate solutions. Both satellite industry and communication start to work on a new paradigm in integrating the space, aerial, and terrestrial networks to form the three-dimensional of the 5G. Low Earth Orbit presents a niche for such projects. However, spacecraft, space stations, satellites, and astronauts are exposed to an increased level of radiation when in space, so it is crucial to evaluate the risks and performance effects associated with extended radiation exposures in missions and space travel in general. This thesis focuses on the LEO, especially in the near-equatorial radiation environment, and how the particles interact with materials in general and with inter-satellite optical wireless communication systems, in particular. The exposed dosage due to the LEO space environment radiation sources, as a function of orbital altitude, orbital inclination, and duration of the inter-satellite Optical Wireless Communication system under radiation, is investigated using existing empirical models. Radiation experiments supported with simulations have made it possible to obtain and evaluate the electron and neutron radiation impact on the optoelectronic components, namely the laser diode at the transmitter and the photodiodes at the receiver subsystems the optical link performance while onboard. Results have shown the degradation of the optoelectronics devices' performance under both radtions, which is affected the performance of the link at the system level. Results show as well the sensitivity of the transmitter subsystems compared to the receiver subsystem. The neutron radiation has been induced a system degradation up to 85% while the electron radiation up to 80%. This shows the importance of such an investigation to predict and take necessary and suitable reliable quality service for future space missions. | ||
