Tier Information
The Rapid Resilient Command and Control (R2C2) program under the United States Space Force (USSF) has four tiers of interface specification documents (ISDs).
Tier 1 and 2 are tactical command and control space vehicle message standards while Tier 3 and 4 are implementation specific interfaces for services in those satellite operating centers (SOCs). The R2C2 Tier 1 ISD clones Object Management Group (OMG) Command Control Mission Systems (C2MS) v1.0 with some alterations and message creations supporting DoD requirements or USSF space domain capabilities. Tier 2 ISDs are the R2C2 standards for system domain capabilities (e.g. Flight Dynamics, Telemetry Tracking & Commanding, Mission Planning & Scheduling, Ground Resource Management, Ground Resource Scheduling, etc.) which are based on Tier 1 messages. The Tier 3 ISDs are for service component’s or product’s interface implementation details while Tier 4 is the mission-specific interface details.
This page includes status guidance for R2C2’s Tier 1 message interface standard and additional alerts with AstroUXDS statuses. For information regarding the other Tiers, contact Astro Support.

DATA-QUALITY
The quality of the data. RAW = No quality check, VALIDATED = Checked and passed, DEGRADED = checked with quality issues.

SEVERITY
Indicates the severity of the Log Message. Scale is traditionally applied to message based on requirements and characteristics of the component or ground system. The severity field may be used to alert the system such as triggering additional visual or audible operator notifications. Debug is typically used by software developers.

XTCE-STATUS
Status codes from the OMG XML Telemetric and Command Data Exchange (XTCE) specification. This status links the OMG XTCE with OMG C2MS in order to represent the command sequence progression against space assets. The most visual and status related fields for common display are INVALID:2, COMPLETED:9, FAILED:10.
If you have a use case where the other values for XTCE-Status ( 1 = ACKNOWLEDGEMENT, 3 = TRANSFERRED_TO_RANGE, 4 = SENT_FROM_RANGE, 5 = RECEIVED, 6 = ACCEPTED, 7 = QUEUED, 8 = EXECUTING) require a status color or symbol please reach out to Astro for assistance.

Additional Guidance
The MNEMONIC.N.SAMPLE.M.Statuses; RED-HIGH, RED-LOW, YELLOW-HIGH, YELLOW-LOW Boolean fields within the mnemonic samples of telemetry data messages indicate thresholds of what state the data is currently in, in relation to the space vehicle qualitative metrics. The recommended color status reflect the accompanying names (e.g. RED-HIGH and RED-LOW are typically used with a Critical/Red AstroUXDS status and similar for the named Yellow fields.)

XTCE Alarm Levels
The OMG XTCE specification defines multiple alarm levels. This is defined within the AlarmConditionsType, AlarmRangesType, and ConcernLevelsType within the XTCE schema. These alarm levels are found within telemetry definitions that can be embedded in messages in the OMG C2MS and R2C2 C2MS message schemas. This section provides guidance for the colors that align to each level if this data is shown on screen. Since AstroUX does not define Watch or Severe levels, Watch is mapped to the same coloring as Warning and Severe is mapped to the same coloring as Critical.
The OMG XTCE and OMG C2MS standards are constantly evolving. The teams are working to better align the statuses given the mismatch of quantity. In the interim, this translation table is our current guidance. We are aware that this can result in one-way translation or inability to reconstitute given duplicate statuses. This will be amended in the future and is stated as low risk given the small amount of use cases that require translating these statuses.
| Value | Design Token | C2MS STATUS | C2MS SEVERITY | Status Symbol |
|---|---|---|---|---|
| NO ALARM | color.status.normal | GREEN | NORMAL | |
| WATCH | color.status.caution | YELLOW | MEDIUM | |
| WARNING | color.status.caution | YELLOW | MEDIUM | |
| DISTRESS | color.status.serious | ORANGE | HIGH | |
| CRITICAL | color.status.critical | RED | CRITICAL | |
| SEVERE | color.status.critical | RED | CRITICAL |
