Abstract:
The International Space Station (ISS) will provide 
investigators around the world a long duration space science and 
technology research capability.  This diverse, geographically-
distributed ISS utilization activity will be supported by 
operations centers in participating partner nations.  NASA will 
integrate and coordinate ISS utilization through a Payload 
Operations Integration Center (POIC) at Marshall Space Flight 
Center.  POIC functions and capabilities are defined.  The 
functions include ISS payload activity planning, payload 
operations control, payload data management, and utilization 
operations integration with the other centers.  The POIC facility 
support these functions.

The payload activity planning function results in summary 
plans and detailed timelines.   POIC planners working with other 
operations centers generate these integrated plans and timelines.  
The POIC facility provides communications, information, and 
planning systems to perform these tasks.

The payload operations control function supports the execution 
of the timelines.  POIC personnel will monitor the execution of 
ISS crew and ground-based payload user timelined activities.  They 
will coordinate timeline changes to avoid activity conflicts.  
POIC communications, telemetry, and command processing systems are 
used to perform payload operations control.

The payload data management function coordinates video, 
science, and housekeeping telemetry collection and distribution.  
The POIC data management team will coordinate payload utilization 
of onboard data systems, Tracking and Data Relay Satellite, and 
ground communications and data systems.

Finally, the POIC will be the hub of ISS utilization 
activities.  By interfacing with the other ISS centers using 
information management and communications systems, the POIC 
personnel will facilitate routine information dissemination and 
coordination.  Additionally the POIC integrates troubleshooting 
and contingency management of ISS utilization when unexpected 
events and malfunctions occur.
