SPACE RADIATION EFFECTS ON OPTICAL TRANSCEIVER SYSTEM OF SATELLITE AT NEAR EQUATORIAL LOW EARTH ORBIT
Abstract
Satellite communications now embarking on a new paradigm in integrating the space, aerial, and terrestrial networks to form the three-dimensional of the 5G. However, spacecraft, space stations, satellites, and astronauts are exposed to an increased level of radiation when in space, hence it is important to evaluate the risks and performance effects associated with extended radiation exposures in missions and space travel in general. This research proposal focuses on the LEO especially at the near-equatorial radiation environment and how the radiation particles in it interact with materials in general and with inter-satellite optical wireless communication systems in particular. The research will include exposing the transmitter (laser) and receiver (photodetector) to space radiation ie the electron radiation and study the degradation effects on the devices with varying dose. The data from the characterisation of devices before and after radiation will be used as input to simulate the optical communication link of the satellites using OptiSystem. The performance of the optical link with transreceiver subjected to space radiation will be investigated using different methods of modulation techniques and analytical modelling of the optical system will be performed.
