Orbitalleihin

Orbitalleihin is a contractual framework for leasing access to orbital infrastructure and assets. It encompasses rights to use satellite capacity, orbital slots, servicing capabilities, and related ground-support resources for a defined period or on a shared-use basis. The term is used in theoretical discussions of space economics and in some science fiction works to describe cooperative utilization of orbital assets.

The coinage combines orbital and leihen, the German verb meaning to lend or borrow, signaling the lending of orbital assets between parties. The concept is not tied to a single jurisdiction and appears mainly in academic and speculative literature.

Orbitalleihin agreements specify ownership-like rights to utilize specific elements of orbital infrastructure, while ownership remains with the provider or a designated operator. Typical elements include transmission capacity, access to a satellite's transponder, sharing of a geostationary orbital slot, or availability of servicing and maintenance support. Terms cover duration, pricing, priority access, and liability, as well as deorbit and end-of-life obligations.

Leasing orbital assets raises regulatory issues such as compliance with ITU spectrum allocations, space traffic management, and space law. Orbitalleihin can lower upfront capital requirements, enable scalable deployment of networks, and support joint ventures or public-private partnerships. However, they pose governance challenges, risk of resource contention, and complex liability arrangements.
