feasibility of using v-sat satellites in library services

Purpose: the main purpose of this research is to assess the feasibility of using vsat satellites in the information services of university libraries.method: the research method is a survey using the topsis model, which indicates that the optimal method of providing the internet is the method that has the greatest distance from negative factors and the least distance from positive factors. the opinions of user organizations, i.e. academic libraries and information centers, have been examined to clarify the necessity of using this method as well as its characteristics and advantages compared to other ways of providing the internet.findings: the findings show that vsat satellite internet can have better conditions for providing services compared to other services such as adsl, optical fiber, wi-fi and wi-max. also, their assessment determined that vsat satellite internet is currently the best way to provide internet based on the criteria of service, support, cost, trust and quality, and ranks second in criteria such as security, confidentiality and service. in conclusion, the priority of solutions to provide library internet using topsis analysis is: vsat service; optical fiber; adsl service; wi-max services and wireless services.conclusion: the results indicate that the vsat satellite network, with advantages in the use of internet services by libraries, plays an important role in improving the quality of these services.
