SDA Selects GMV to Enhance Space Traffic Coordination System
The Space Data Association (SDA) has chosen Spanish technology provider GMV to upgrade and manage its global space traffic coordination platform, a decision announced on September 16, 2023. This initiative will commence in early 2024 and aims to enhance the existing Space Safety Portal (SSP), which assesses the risk of satellite collisions by analyzing flight dynamics from SDA members and public data sources.
Since its establishment in 2009, the SSP has been integral to the SDA’s mission. Currently, the system is maintained by ComSpOC, a company specializing in U.S. space situational awareness (SSA). The need for a next-generation system has become increasingly urgent due to the growing congestion in Earth’s orbits and the heightened risk of collisions.
Critical Upgrade for Space Safety
Joe Chan, chairman of SDA, emphasized the timeliness of this upgrade, particularly as the U.S. Traffic Coordination System for Space (TraCSS) faces budget constraints. “Avoiding collisions that can create long-lived, hazardous space debris is more important than ever given the increased utilization of space,” Chan stated in an email. He noted that while SDA advocates for the development of publicly funded space traffic coordination systems, none are yet fully operational.
The SDA serves as a low-barrier entry point for satellite operators, requiring membership for access to its services. Members are expected to share vital data, including advanced maneuver information, akin to following a traffic code of conduct. “It is only effective if all vehicles on the road follow the same rules,” Chan noted. He pointed out that over 700 satellites contribute data to the platform, representing approximately half of all active spacecraft in geostationary orbit.
Non-Profit Structure Offers Unique Advantages
In a landscape where numerous commercial space traffic management platforms have emerged, Chan highlighted the advantages of the SDA’s non-profit model. Founded by satellite operators, this structure ensures a level of protection for sensitive data that may not be present in commercial entities. The SDA aims to function as a data coordinator and innovation hub, uniting all SSA providers.
“As a fully independent, non-commercial entity and as a permanent observer within UNOOSA, SDA can act as the facilitator and fuse together information to achieve global space traffic coordination,” Chan explained.
He stressed the necessity of data sharing within the industry to avoid remaining in a fragmented state. A unified approach would centralize relevant data, allowing it to be vetted and transformed into a common format for broader availability.
The upgraded SSP is set to introduce several new capabilities, which will enhance its effectiveness in managing space traffic and mitigating collision risks in increasingly crowded orbits. As the global space environment continues to evolve, the SDA’s collaboration with GMV represents a significant step forward in ensuring the safety and sustainability of space operations.
