In September 2019, the Interagency Operations Advisory Group (IOAG) Spacecraft Emergency Cross Support (SECS) Working Group presented the SECS Standard Operating Processes and Procedures (SOP) to the annual IOAG conference (IOAG-23). The SOP presents a harmonised approach for emergency recovery support entailing processes and services that reduce response times related to critical emergency situations. The implementation of these services will be achieved by:

    Encouraging member agencies to follow the guidelines outlined in the SOP

    Encouraging member agencies to establish arrangements that enable execution of SECS

    The SOP provides guidance to agency Service Users, i.e. any agency mission, current or future, that may require additional support beyond their routine and contingency support, in order to recover from an Emergency Condition that threatens the life of the spacecraft. Initially, support is limited to IOAG member Agencies; however, the support, as defined, has the potential to expand the “service user” and “service provider” base. In addition, the IOAG is surveying interest from Commercial Service Providers for participation. The SECS SOP defines three specific categories of standard support that can be made available by service providers.

    Committed Support

    Acknowledgement Support

    Non-Registered Support

    The SOP describes the “recovery” services that service providers may perform, covering a wide variety of contingency situations, including:

    Downlink or uplink engineering services for diagnostics (no real-time telemetry or telecommand transfer)

    Tracking data delivery and/or processing

    Full telemetry, tracking and command (TT&C) Services

    These services require the support of various branches of a service provider’s infrastructure, namely:

    Flight dynamics

    Ground stations

    Data communications

    Asset scheduling

    The SOP deals with items of particular interest to mission managers, including what constitutes a spacecraft emergency, radio frequency (RF) licensing, points of contact, and the SECS asset database. As a “Proof of Concept”, various demonstration exercises were performed utilising stations from multiple agencies tracking spacecraft which, although not actually in emergency, require preparation activities in line with a contingency acquisition. Completion of this SOP is a major milestone for this working group. The document focuses on emergency support for robotic missions. The working group plans to expand its scope to encompass emergency support for human spaceflight missions. More information on the IOAG can be found on the following website: https://www.ioag.org.
