OPSCOM-1 Notes
• Experiment was performed using CGBA as a
proxy onboard to route traffic to the
METERON laptop
• Cu-Boulder’s ground site was also used to
proxy DTN traffic to ESA
– No ACS was used for this experiment
– Custody Transfer was not used for this experiment

METERON Laptop Configuration
• OPSCOM-2 will be executed in 3rd annual quarter 2014
– Custody Transfer will be enabled
– ACS will also be used for this experiment
• The METERON ISS Laptop will need to be reconfigured to
route directly to HOSC DTN Node
– ESA has access to this load and will make the configation
changes for the onboard laptop
– ESA will also need to make similar configuration changes to the
DTN node located at B.USOC
– MSFC will make the necessary database modification to route
the redefined ESA bundles and data appropriately
– MSFC will provide ESA with a Payload Rack Checkout Unit
(PRCU) to verify the changes in a high fidelity test environment
