Demonstrable technologies have proven themselves in laboratory tests and have begun experimentation and testing in space. These technologies are considered to be Technology Readiness Level (TRL) 7 and above.
Some of the demonstrable technologies that SCaN is currently working on are:
Space Communications and Navigation (SCaN) is developing a set of international standards, collectively referred to as Disruption Tolerant Networking (DTN) standards, to support internetworking in space.
Optical communication is a form of long distance communication that uses light as a means of transmitting information.
The first radio was invented late in the nineteenth century following several decades of improved understanding of the physics of electromagnetism.
