CCSDS Spring Meeting 2017, San Antonio, TX

2. Why Change a Running System?
> CCSDS GSOC/DLR > Stefan Gärtner >
Why Change a Running System?
More entities are interested in performing at least parts of satellite operations (e.g. payload operations)
Establish a system scalable to mission with different degrees of operations complexity – keep multi-mission operations
Closer interaction with satellite providers / AIT phase
Provide systems or parts of them for supporting / performing operations at other sites
Increase the maintainability and automation of the overall system (w.r.t interfaces/standards, flexibility, re-use / plug and play)

Typical FOS for Current Missions

4. Demands by AIT and Operations
> CCSDS GSOC/DLR > Stefan Gärtner >
Demands by AIT and Operations
modularity
FOS setup independent of where individual functions and processes are deployed and executed
scalability
non-demanding standard missions
complex prototype missions
multi-mission
integration in multi-mission environment
flexibility
alter mission operations concept and system setup after mission start
distributed operations
securely perform operations from inside and outside GSOC internal environment

The Vision

6. > CCSDS MO @ GSOC/DLR > Stefan Gärtner > 2017-05-08
Current Status
first prototype FOS setup in GSOC’s operational environment
handle all IT and operational security aspects like firewalls and DMZs
setup of a virtual machine test environment including user setup and access
prototype of a messaging bus in a single network for connecting CCSDS/MO services via MAL
prototype realization of a M&C service provider located on the external interface layer of the GECCOS M&C system (to be evolved to a EGS-CC prototype MO adapter)
prototype realization of Satmon telemetry display as M&C service consumer
start of integration effort EGS-CC / test setups

7. Internal MO Message Transport Details
> CCSDS GSOC/DLR > Stefan Gärtner >
Internal MO Message Transport Details
requirements:
need a secure way to traverse network boundaries / firewalls in a defined and controlled way
filtering of data stream – users will be allowed to receive only a subset of information / perform only a defined subset of activities
need adequate logging on different levels for security and tracing purposes
 broker-based messaging protocol
AMQP
MQTT
Kafka
...

8. > CCSDS MO @ GSOC/DLR > Stefan Gärtner > 2017-05-08
Next Steps
finalize MO / messaging setup for further distribution of M&C services also to distinct networks, e.g. the GSOC office environment and an external partner
verify CCSDS MO/MAL performance
identify and find a solution for not yet defined MO services
direct real-time commanding of an engineering model using clients outside GSOC
check operational aspect of parallel commanding
exchange GSOC GECCOS/SCOS based kernel with EGS-CC using an MO adapter

Mini Mission Control Center
exhibition at DLR open house October 2016
simulation of a LEO satellite orbiting visitors
task for the visitor: take a selfie
i.e. command the satellite to perform data takes at a calculated orbit position and downlink them on next ground station contact
