LunaNet Interoperability Specification


The purpose of the LunaNet Interoperability Specification (LNIS) is to define a framework of mutually agreed-upon standards to be applied by users and service providers in a cooperative network supporting missions on and around the Moon. The framework would apply to communication transmission services for science, exploration and commercial operations, distribution of navigation and timing references, and sharing of information such as space weather alerts. These standards can be introduced as part of upcoming missions to and around the Moon and can accommodate expansion as new commercial and government users and service providers join in an open and evolving architecture. The standards are intended to be compatible with other space communications standards established to date, but are focused on lunar operations, and in particular future lunar communications relay and navigation capabilities.

The development of the LunaNet Interoperability Specification has been a collaboration between NASA and the European Space Agency (ESA). As the specification is refined and new versions are produced, the effort will continue to seek input from the broad community of potential commercial service providers, lunar mission users, and other space agencies.
