- Abstract
In recent years, the growth of space activities has increased the space debris in Earth‘s orbits. By now, there are more than 9000 objects larger than 10 cm length around Earth. The biggest problem is that debris at altitude more than 1500 km stays in orbits forever and increase density of objects in these orbits. Geostationary orbit has considerable potential for telecommunication activities. The current operational satellites in GEO need to had substituted by a new ones, this means stable debris in geostationary orbit area. There are 900 reported objects in GEO at the start of 2002, of which 28Countries and international agencies and committees in space activities such as NASA, ESA, and IADC documented their research results in standards and recommended documents for mitigation of space debris. In these documents, requirements and strategies of disposal or re-orbiting of spacecrafts and satellites at the end-of-life are described and in all space missions, these requirements of mission design shall be considered and satisfied. ZOHREH, the first Iranian telecommunication satellite is planed to be inserted into GEO in 26°E longitude. It’s estimated that ZOHREH will have 15 years life time and at the end-of-life according to IADC recommendations, shall be re-orbited to upper orbits above GEO area. Here, after a review of disposal and re-orbiting satellites strategies history at the end-of-life, a disposal scenario is suggested for ZOHREH at her end-of-life and its effects on space environment is evaluated in long term. To achieve this, the orbital analysis including zonal and tesseral harmonics of the Earth’s gravity potential, luni-solar gravitational attraction and the solar radiation pressure. According to the results and effects of satellite re-orbiting on GEO, re-orbiting scenario is suggested.
