MOOS System Concept
MARS Cabled Observatory
Key System Concepts
• Reliability
• Flexibility
– Moored systems
– Cabled observatories
• Scalability
– Resource constrained/rich
– Many platforms, many instruments
• Interoperability
– Platform-to-platform
– System-to-system
• Capability
– Real-time (or nearly so) telemetry and control
– Event Detection
Instrument Integration
• Mostly serial instruments
• COTS and custom
• Proprietary protocols
– Control, data formats
• Spectrum of machine/human
friendliness
• Unfavorable economics for interface
standards

SIAM Functions
• Data Acquisition
– accurate time, but not hard RT (maybe should be)
– connected, not connected
• Local data archive
• Telemetry, delivery to SSDS
• Resource management
– energy, bandwidth, data storage
• System diagnostics
• Event detection...
SIAM Features
• Flexible architecture
–
–
–
–
Distributed, Scaleable, Interoperable
Plug-and-Work, PUCK compatible
Operable across different resource regimes
Field upgradeable
• Instrument Service Framework
–
–
–
–
–
Ease instrument integration
Uniform network instrument interface
Modular, stand-alone
Open, extensible
Provides facilities for logging, time-stamping , resource
management, data summarization
– Polled, streaming instruments
– Abstractions for communications/power ports, data logs
– Custom hooks for platform-specific hardware
