Earth station system plays an important role to ensure that a satellite communication system runs efficiently. Redundancies of the subsystems and regular maintenance planning can improve the earth station system. Organising system affordability can be challenging as more redundancies would acquire more maintenance. Thus, a sustainable framework that considers an earth station system's reliability, cost, and maintainability was modelled. 2-parallel, 3-parallel, and 4-parallel earth station system configurations were studied with five mean time between failures (MTBF). The results showed that an earth station that was configured with 2-parallel configuration provided an optimum reliability system performance though both 3-parallel and 4-parallel configuration provided higher reliability. Moreover, the 2-parallel configuration was also cheaper in terms of operational cost if compared to the 3-parallel and the 4-parallel configurations. Hence, this sustainable framework comprising the reliability and operational cost elements were modelled based on the 2-parallel configuration with the proposed maintenance activities. Moreover, the computed root mean square (RMS) values for both new reliability and new operational cost models yielded smallest values of 20.84% and 22.82% respectively. Thus, these RMS values for both reliability and operational cost models based on 2-parallel configuration are suitable to be applied in the earth station system design.

“…As reported by [44], preventive maintenance is carried out in pre-defined intervals or according to prescribed criteria; while corrective maintenance is carried out after a fault has been recognized. Preventive and predictive maintenance activities are considering together because both have the objective to optimize the efficiency of the system by anticipating failures [38]. On the other hand, corrective maintenance is based on the prevention of possible failures of a system with the objective to prevent failure costs [38].…”

The Architecture-Engineering-Construction-Operation (AECO) industry is responsible for a very high environmental degradation. In this context, the Operation and Maintenance (O&M) phase of building life cycle is recognized as the highest influencer of the industry's environmental impact. Even if sustainable constructions refer to improve the efficiency of buildings throughout more sustainable processes, such as waste-generation reduction and resource-use optimization, most efforts have focused on improving energy efficiency during O&M. Especially, being maintenance a critical activity to optimize building management, a framework to measure the effects on environmental sustainability seems to be missing in the facility management field. The present research introduces a framework for measuring the environmental impact of maintenance activities to support facility managers to (i) calculate the effectiveness of maintenance choices, (ii) guide the maintenance activities over times, (iii) optimize the environmental effect of maintenance activities. After selecting the Ecological Footprint as the best methodology for these purposes, the authors implement the calculation model, and test it on four case study buildings. Results highlight the potential of such a model to guide facility managers throughout different maintenance strategies. Measuring the potential gains over a time span of 50 years, the total impact of predictive maintenance approach is the 5% higher than the corrective one. However, future improvements need to collect more data about the maintenance activities to better specify the calculations. Digital technology, such as a network of IoT for maintenance monitoring, would help the data collection and better test the model and its impact on the maintenance procedure.

Earth Station(s), Mission Operations Center (MOC), Science Operations Center (SOC), and the supporting infrastructure that connects them all constitute a ground network of communications satellite systems. As more Earth Stations are added to the ground network, additional aspects should be considered to ensure that the MOC can communicate with all the Earth Stations in the network. It also needs constant upgrades to ensure greater reliability and performance. The reliability of the geostationary satellite control Earth Station system can be improvised by designing the system with sufficient subsystem redundancies, numerous tests during the planning stage, and only the best components for its subsystems. Suitable maintenance actions performed on a regular basis also play a significant role in preventing cost overruns and undesirable failures. Therefore, this paper introduces a sustainable framework which encompasses reliability, affordability, and maintainability of an Earth Station system which is very crucial in system design.
