Indian Space & Research Organisation (ISRO)

Solution

Indian Space & Research Organisation (ISRO) successfully disposed of one of its satellites after it completed its operational life in orbit. The INSAT-4B underwent Post Mission Disposal (PMD) at the end of its service, followed by decommissioning. The development is in compliance with the UN and the Inter-Agency Space Debris Coordination Committee (IADC) recommended space debris mitigation guidelines. The IADC guidelines provide guidance for limiting the generation of orbital debris both during and after space operations. The guidelines also define accepted disposal orbits and other conditions, such as the timeline for abandoning commonly used orbits and controlling the risk to people and property on the Earth.
