Space is becoming increasingly congested due to rising numbers of on-orbit satellites and debris objects. Uncontrolled growth will severely affect future space operations. NASA Ames has developed a novel patent-pending technology known as Space Traffic Management (STM) which provides a robust framework for on-orbit coordination of activities to enhance the safety, stability, and sustainability of operations in the space environment.
The STM system is critical for ensuring that the expanding orbital population operates safely and efficiently, avoiding collisions and radio-frequency interference while still facilitating widespread space operations in an increasingly congested space environment. Additionally, it meets the objectives associated with the transition of civil STM from the Department of Defense to a civilian entity.
The STM architecture forms the framework for an STM ecosystem, which enables the addition of third parties that can identify and fill niches by providing new, useful services. By making the STM functions available as services, the architecture reduces the amount of expertise that must be available internally within a particular organization, thereby reducing the barriers to operating in space and providing participants with the information necessary to behave responsibly.
Operational support for collision avoidance, separation, etc., is managed through a decentralized architecture, rather than via a single centralized government-administered system. The STM system is based on the use of standardized Application Programming Interfaces (API) to allow easier interconnection and conceptual definition of roles to more easily allow suppliers with different capabilities to add value to the ecosystem. The architecture handles basic functions including registration, discovery, authentication of participants, and auditable tracking of data provenance and integrity. The technology is able to integrate data from multiple sources.
