Interagency Operations Advisory Group Industry Exchange Workshop Presented by : IOAG Chair (Michael Schmidt, ESA) on behalf of the IOAG
IOAG Role The IOAG (Interagency Operations Advisory Groups) provides a forum for identifying common needs across multiple international agencies for coordinating space communications policy, high-level procedures, technical interfaces, and other matters related to interoperability and space communications. Enable Safe, Secure and Efficient interoperable mission operations Enable higher rate throughput for Science, Earth and Exploration missions Provide responsive networks around the Earth, Moon, and Mars to enable future Exploration and Science missions The IOAG was founded by the Interoperability Plenary (IOP) to: understand issues related to interagency interoperability and other space communications matters; identify common solutions complying with IOP guidance; recommend resolutions to the IOP for specific actions created by the IOP and put on the IOAG. 2
Interaction with Commercial Providers and Operators The latest IOP meeting addressed among others the interaction with Commercial Providers and Operators and agreed on the following resolutions: The IOP acknowledges the potential benefits of a closer interaction with commercial providers and operators of operations services. The IOP asks the IOAG to explore options and establish mechanisms to engage with relevant commercial providers as an initial step. 3

APPENDIX 23
Spacecraft Emergency Cross Support Service Overview The IOAG established the Spacecraft Emergency Cross Support Working Group (SECSWG) in 2014 in response to an IOP-3 recommendation Spacecraft Emergency Cross Support (SECS) services are: Inter-agency cross support services provided during a spacecraft emergency Minimal-to-zero emergency support coordination between the user mission and the service provider conducted prior to emergency Include basic engineering and standard TT&C services, when possible, on a best effort basis SECSWG Goals: Establish a process and guidelines to make emergency support a permanent cross-support capability between space agencies. Implement and maintain SECS services with minimal investment from the participating agencies Participating Agencies: ASI, CNES, DLR, ESA, JAXA, KARI, NASA 17 September 2019 24
Emergency Definition Spacecraft emergency mode is the anomalous state of the spacecraft in which its persistence will result in the loss of the spacecraft entirely or the loss of any of the spacecraft s essential faculties (payload excluded). For human space flight missions, any external or internal conditions that could negatively affect the health and safety of the crewmembers are causes for spacecraft emergency mode. Any ground station failure by itself is not a direct cause for declaring the spacecraft in emergency mode. SECS is only related to establishing a Telemetry, Tracking and Command (TT&C) link to the spacecraft for recovery operations as well as engineering services. It does not apply to science or mission data acquisition. 17 September 2019 25
Services Available for Emergency Cross Support Engineering Services IOAG Standard TT&C Services Provided as a best effort approach to determine the status of the spacecraft and/or to recover from the anomaly condition These core services, as listed in the IOAG Service Catalog, can be provided during an emergency if the missions meets the pre- conditions specified in the IOAG SECS SOP Services include: Spacecraft Search Service Downlink signal analysis service Uplink Adjustment Service Services include: Forward Data Delivery Services Return Data Delivery Services Radiometric Services 17 September 2019 26
SECS Standard Operating Processes and Procedures (SOP) Describes recommended actions for service providers and missions that simplifies the real-time coordination process and reduces the response time during an emergency Ex. Early coordination on procedures and Points of Contact (POC), RF licensing, creating configuration files at the station, maintaining current trajectory files Describes services available and frequently used during emergency cross support Lists Service Provider POCs and available ground stations; provides a template for exchanging spacecraft specification data SECS SOP draft is currently under review by the IOAG 17 September 2019 27
Implementations Options Support Scenarios As Described in Standard Operating Procedure ACKNOWLEDGED COMMITTED NON-REGISTERED The provider agrees, on a best effort basis, to: 1. Real Time preparation of Ground Station Configuration The provider agrees to: 1. Maintain a TT&C configuration on the desired ground station (untested, no periodic validation) 2. Maintain a functioning FD infrastructure for processing Orbital Predicts and Radiometric Data The provider agrees to: 1. Maintain RF licenses for nominated Spacecraft 2. Maintain a functioning TT&C configuration on the desired ground station 3. Maintain a functioning Comms infrastructure between the agencies involved 4. Maintain a functioning FD infrastructure for processing Orbital Predicts and Radiometric Data 5. Perform periodic validation tracks (6 -12 monthly) on nominated Spacecraft Notes: In each of the three cases the services provided will depend on the emergency situation. At a minimum, engineering services may be available. If the emergency state permits, also full TM/TC and radiometric services. Also, terms of support scenarios may vary between service providers. Low Level of Mission-Service Provider Pre-Coordination High Increased Response Time Higher Level of Preparation 17 September 2019 28
Potential Opportunities for Industry IOAG believes that these services present an industry engagement opportunity. The basic concepts documented in the SOP can be leveraged by industry to serve as candidate emergency cross support providers. Potential Benefits Requires minimal industry investment, presenting a possible business case Creates a standardized process capability between agencies as well as industry Reduces confusion during an emergency Simplifies the interface to other agencies Identifies appropriate points of contact Creates a centralized location listing available ground stations and points of contact 17 September 2019 29
