The Space Data Association (SDA) has chosen Spanish technology provider GMV to enhance and operate its global space traffic coordination platform. This decision was announced on September 16, 2023, and the upgraded system is set to begin operations in early 2024. The initiative aims to improve the Space Safety Portal (SSP), which processes flight dynamics information from SDA members and public sources to deliver conjunction assessment and warning services.
Originally established shortly after SDA’s founding in 2009, the SSP is currently managed by ComSpOC, a U.S.-based specialist in space situational awareness (SSA). Several companies, including ComSpOC, competed for the opportunity to deliver a next-generation system capable of managing the increasing congestion in space and the associated collision risks.
SDA Chairman Joe Chan emphasized the urgency of this upgrade, especially as the U.S. Traffic Coordination System for Space (TraCSS) encounters budget cuts. “Avoiding collisions which can cause long-lived, hazardous space debris is more important than ever given the increased utilization of space,” Chan stated via email. He added that while SDA promotes the development of publicly funded space traffic coordination systems, none are fully operational at this time.
Facilitating Global Coordination
SDA aims to provide a low-barrier entry point for satellite operators to engage in SSA. Membership requires operators to pay for access to SDA services and to share crucial data, including advanced maneuver information. Chan likened this to a traffic code of conduct, saying, “It is only effective if all vehicles on the road follow the same rules.” He believes that despite a crowded orbital environment, safety can still be maintained if operators adhere to established best practices.
Currently, over 700 satellites contribute data to the SSP, representing approximately half of all active spacecraft in geostationary orbit. This extensive participation underscores the platform’s significance in global space management.
The Value of a Non-Profit Structure
In light of the growing number of commercial space traffic management platforms, Chan highlighted the unique advantages of SDA’s non-profit structure, which is founded by satellite operators. This framework provides a safeguard for sensitive data. “As a fully independent, non-commercial entity and as a permanent observer within the United Nations Office of Outer Space Affairs (UNOOSA), SDA can act as a facilitator/partner and fuse together information to fully achieve global Space Traffic Coordination,” he explained.
Chan stressed the importance of data sharing within the industry. He noted, “If we don’t, we will remain in the current status quo, where data is ultimately fragmented within different SSA systems.” A unified approach could consolidate relevant data into a central repository, allowing for better vetting and availability when needed.
The upgraded SSP is poised to introduce several new capabilities that will enhance its operational efficiency and responsiveness to the ever-evolving demands of space traffic management. As the space industry continues to grow, the SDA’s initiatives are expected to play a crucial role in ensuring the safety and sustainability of space activities.
