- Family reference-profile markers
- ● 6 Standard · ○ 15 Common · △ 0 Variant · 0 unmarked
- Component coverage
- 5 released source-BOM records
- Relationship meaning
- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

GNSS / network master clock
GNSS·네트워크 마스터클록The master clock taking accurate time from satellites and distributing it as the ship's single time reference.
Reference pattern · 1 duty + backupView Component record →COMP-644 · Panel / ElectronicsRedundant time server
이중화 시각서버A second time source keeping the ship's systems synchronised if the primary fails.
Reference pattern · 1 setView Component record →COMP-645 · Panel / ElectronicsNTP / PTP distribution gateway
NTP·PTP 분배 게이트웨이The gateway distributing time over the ship's networks, so logs and recordings across systems agree.
