End-of-life disposal in inclined geosynchronous orbits

Significantly Inclined Geosynchronous Orbits (IGO) are currently considered for various applications, like satellite navigation systems, intelligence and telecommunications. In the light of these developments, the aim of this report is to review the current definition of the Geosynchronous Protected Region, assessing if it would need an extension. Special attention is paid to the end-of-life disposal, in order to check the potential weaknesses of the current IADC formula and re-orbiting recommendations, focusing on the consequences of having operational orbits characterized by medium or high inclinations.
