## 5 Conclusions  
The conducted analyses provided a comprehensive knowledge of the operational capacity of the nanosatellite dedicated to capturing images of a selected area. The research focused on several key aspects, including propulsion efficiency, the optimum selection of the weight of satellite and of fuel, swath width, and the influence of orbital parameters on the nanosatellite's ability to perform observation missions effectively. In particular, it was demonstrated that the selection of the appropriate propulsion system is of key importance for improving fuel efficiency, which enables to perform more complex orbital manoeuvres while, at the same time, reducing fuel consumption. The analysis revealed that the precise planning of manoeuvres such as, for example, changing the altitude of the orbit by means of the Hohmann transfer, allows for the minimisation of fuel costs and maintaining orbital stability. The conducted research also enabled to assess the influence of the satellite's weight on the swath width and the duration of flight over the target area. The results demonstrated that a higher weight of the satellite, with correctly selected sensor parameters, enables an increase in the swath width, which is important from the point of view of missions that are aimed at monitoring large areas. Furthermore, the analysis of the flight duration highlighted the fact that the key factor is the inclination of the satellite's trajectory in reference to the equator, as it influences the actual velocity relative to the Earth's surface, and thus, the efficiency of data acquisition. The analysis of inclination changing manoeuvres revealed their high energy and fuel costs for nanosatellites. This provides an inspiration to search for alternative solutions. In this context, the authors proposed to use manoeuvres to change the orientation. They are performed with the use of reaction wheels that consume power resources instead of fuel and at the same time enable prolonging the duration of the observation of the area of interest. The power system of the nanosatellite was considered to be well-optimised in terms of intensive orientation-changing operations. Thanks to that, the satellite may perform short tilting manoeuvres that have only a slight influence on the availability of energy resources. The obtained results provide a solid basis for further research. It was demonstrated that satellites in the nano and nano+ classes may be effectively used in various missions. Although this study does not introduce new equations or algorithms, it provides an evaluation of existing orbital manoeuvres from the perspective of their application to nanosatellite missions, supporting designers in making decisions at an early stage of mission planning. Future research projects should be aimed at the optimisation of orbital manoeuvres, with particular focus on the strategies that minimise fuel and energy consumption in order to improve the efficiency of nanosatellites and to enable the realisation of more complex, long-term missions in the dynamically changing orbital conditions. In the future, it is also worth considering the application of optimisation algorithms that will enable the more precise planning of orbital manoeuvres by minimising fuel and energy consumption and maximising the operational efficiency of nanosatellites. The research results highlight the importance of precise planning and the optimisation of mission parameters, which is crucial for the maximisation of the efficiency of nanosatellites when resources are limited. **Author Contributions:** Conceptualization, M.K. ; methodology, M.L. and M.K. ; software, M.L. ; validation, M.L. ; formal analysis, M.L. ; investigation, M.L. ; resources, M.L. ; data creation, M.L. and M.K. ; writing--original draft preparation, M.L. ; writing--review and editing, M.K. ; visualization, M.L. ; supervision, M.L. and M.K. ; project administration, M.K. ; funding acquisition, M.K.
