Design Considerations of a Space Elevator Apex Anchor and GEO Node –
This year, ISEC chose to address the design considerations for the Apex Anchor and Geosynchronous Earth Orbit (GEO) Node. As was discussed in the Architectures and Roadmap report, ISEC understands where the technologies are today and where we would like them to be in order to reach Initial Operational Capability (IOC). The goal of this study team is to add to the “body of knowledge” relative to the two topics addressed herein. To ensure complete understanding during this study report, the following definitions were developed:
- Space Elevator Column
- Earth Port & Earth Port Region
- GEO Node & GEO Region
- Apex Anchor & Apex Anchor Region
In addition, the needs [functional requirements] were discussed for each of those regions and complexes. Throughout the text, the initial destination is described as the IOC for the Space Transportation System. The Space Elevator Transportation System is comprised of one Earth Port with two tether termini, multiple Apex Anchors supporting 100,000 km Tethers, 14 Tether Climbers, and a single Headquarters and Primary Operations Center. The GEO Node supports the Space Elevator Transportation System with a range of “overhead’ functions; e.g. test, safety, and support.
