GMSEC Components

Alert Notification System Router (ANSR)

ANSR is an alert system that autonomously pages or emails mission operators in case of events or anomalies during lights-out satellite operations. Although ANSR does not detect events or determine how to respond to them, other components can instruct ANSR to page an operator or a team through GMSEC directives.

Countdown Clock (CC)

CC converts a schedule of upcoming events into a configurable countdown display and publishes log messages corresponding to the countdown of start and end times for each event. It supports two different display modes: multi-record and alternating record.

Event Analyzer (EAN)

Event Analyzer provides a view of a real-time message content published onto the middleware bus and messages retrieved from the historical archive.

Event Archive (EA)

Event Archive archives published messages into a database and provides customizable database management features.

Event Report (EAR)

Event Report subsystem performs statistical collections, data analysis, and data mining of the event databases generated by the GREAT Event subsystem.

GMSEC Remote Access Service Provider (GRASP)

GRASP transports GMSEC messages from one GMSEC-compliant network to another. By leveraging GRASP, select mission and GMSEC capabilities can be available to users without direct access to a secure network.

EAGLE

EAGLE is an archiving service for storing messages published to the middleware bus into a database. Messages are defined in the Object Management Group Command and Control Message Specification document and the NASA Addendum to that specification. EAGLE supports the Elasticsearch data store, the Kibana web interface, MySQL/MariaDB relational databases and will soon support NoSQL database via MongoDB.

GMSEC Environmental Diagnostic Analysis Tool (GEDAT)

GEDAT offers a centralized visual representation of a GMSEC-based system. It identifies all components connected to the bus, validates nominal operations, and recognizes error conditions. GEDAT monitors heartbeat messages to identify and display the status of components communicating via publish/subscribe messaging.

NOTE

Note offers operator the ability to publish text as a GMSEC LOG message. It consists of the Note Service and Note Graphical User Interface.

Performance Test Utility (PTU)

PTU collects message timing data based on GMSEC message activity, analyzes it, and presents results in an easy-to-read format. It allows users to create and modify performance tests, automate general-purpose performance testing, and analyze direct socket-to-socket connections on the same network for latency comparison.

Room Alert Adaptor (RAA)

RAA allows users to set up an environmental monitoring system using GMSEC-compliant components. RAA can be used as a system service or run in the background. Other GMSEC-compliant components, such as GEDAT and CAT can be integrated with RAA for centralized display and automation of tasks associated with the status monitoring.

System Agent (SA)

SystemAgent supplies health information of the computer hosting the agent to other GMSEC components using a middleware-based architecture. Traditionally, early problem detection and error correction of a machine required physical presence for system monitoring. Having an agent that reports machine’s health using the middleware paradigm offers a generic, automated, and centralized monitoring tool for the entire GMSEC system.

XTCE Read and Edit (XRAE)

XRAE allows users to view XTCE files in a human-readable form and partially edit them. The viewing capabilities of XRAE encompass most features of XTCE 1.0, displaying them in a user-friendly and high-level format. The editing features allow to modify some characteristics of SpaceSystem, Parameter, and ParameterTypes.

Criteria Action Table (CAT) (Deprecated)

The Criteria Action Table is an independent component developed for the purpose of monitoring real-time system messages against a set of pre-defined rules. CAT has been deprecated and replaced by GEMU.
