The Space Data Association (SDA) has signed an agreement with the US Department of Defense (DoD) to participate in the latter’s Space Situational Awareness (SSA) Data Sharing programme.

Under the terms of agreement, the signatories would formally collaborate on matters concerning space situational awareness, including mitigation of electromagnetic interference (EMI) and radiofrequency interference (RFI).

SDA chairman Ron Busch said: "This agreement represents a major milestone in space situational awareness, creating a framework to exchange data.

"The benefit is that critical analyses will be far more robust, improving our knowledge of the space operational environment.

"The agreement demonstrates that even the most advanced government space operators recognise SDA’s ability to provide important and valuable services to manage operational risk, including performing conjunction assessments and activities to mitigate electromagnetic interference (EMI).

"The benefit is that critical analyses will be far more robust, improving our knowledge of the space operational environment."

"SDA will continue to collaborate with and seek participation by other governmental, commercial and intergovernmental stakeholders as we promote safe and responsible operations and preservation of the space environment."

Established by satellite operators to improve the safety and efficiency of space operations, SDA seeks the participation of all global satellite operators in the programme.

Administered by the US Strategic Command (USSTRATCOM), SSA Data Sharing programme aims to enhance the safety, security and sustainability of the space domain by bolstering space situational awareness through a series of basic and advanced services.

Specific services include anomaly resolution, collision avoidance, conjunction assessment, end-of-life disposal, deorbit and re-entry planning support, launch support and EMI investigation.

Space situational awareness exchanges are expected to assist partners in launch support, manoeuvre planning, EMI reporting and investigations, while providing support for launch anomalies and de-commissioning activities, as well as on-orbit conjunction assessments.
