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) has completed successful testing of disruption tolerant networking (DTN) in space. Scientists realize that DTN technologies are required to provide reliable operation of a space-based Internet that will improve the quantity and quality of our space based communications.
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.
