in the 1980s, the convention governing INMARSAT was amended to include improvements in aeronautical communications, notably for public safety.

In the mid-1990s, there was contrasting views among member states for the agency's future. There was a growing realization among the member states that the organization's business assets needed to be privatized, mainly because of the competitive nature of the satellite communication industry and the unwillingness of many member states to invest money into INMARSAT to improve its network. There were also many which believed in the importance of maintaining the organization's role in overseeing maritime satellite communication. The issue was resolved in a session in April 1998, which resulted in the amendment of the
