Abstract: | Retired geosynchronous (GEO) communication satellites affect the GEO orbit environment in outer space. According to the new
concept of modern design, the authors propose creatively a method of reusing retired GEO communication satellites, through
adjusting retired GEO satellites to slightly inclined orbit geosynchronous (SIGSO) satellites. After these retired satellites
are applied to the navigation and communication system, integrity of navigation system and positioning accuracy of the system
is improved. Meanwhile, some transponders on these retired satellites can be used to establish a new satellite communication
service, and initiate the study and utilization of the multi-life cycle for retired satellites. Experimental results show
that this project has significant social value and can make remarkable economic benefit.
