Spatiam Corporation has created a space communications platform designed to handle delays and disruptions in data transmission. The system uses Delay and Disruption Tolerant Networking (DTN), which can manage the challenges of long-distance space communication.
The International Space Station (ISS) National Laboratory played a key role in testing this new platform. It provided a real-world setting to validate the technology, pushing it to Technology Readiness Level (TRL) 7, just one step away from flight certification. The system demonstrated its ability to keep networks operational by transferring data, including telemetry, text, binary files, and even audio and video streams between space and Earth.
Vint Cerf, a pioneer in internet protocols and co-developer of DTN, pointed out that traditional TCP/IP networks fail in deep space. High latency and frequent disruptions make these outdated protocols unsuitable for interplanetary communications. DTN, Cerf believes, is crucial for enabling reliable data transfer over vast distances.
Alberto Montilla, CEO of Spatiam, also emphasized the significance of the ISS in testing their technology. He noted that the station’s environment provided essential operational experience in managing complex space networks.
The demonstration lasted 18 days and included over 95 tests, one of which involved bundle-in-bundle encapsulation to ensure secure data transfer. The platform also supported multiple network administrators and the streaming of high-definition video, vital for future missions to the Moon and Mars. Spatiam plans to extend its DTN system to support lunar operations and commercial space stations.
At the Space Software Summit in Boulder, Colorado, Spatiam presented these advancements, highlighting their potential to create commercial interplanetary communication networks. The success of the ISS demonstration represents a major milestone in the development of space networks for future missions beyond Earth’s orbit.
