MISMMS Embedded VMTI Parent Metadata

This MISB ST 0902 cross-layer rule validates that claimed MISMMS packets carrying embedded MISB ST 0903 VMTI in MISB ST 0601 Tag 74 preserve the parent metadata required by the profile.

For each decoded parent packet containing Tag 74, the rule checks that the same MISB ST 0601 packet also contains:

  • Tag 2: Precision Time Stamp
  • Tag 23: Frame Center Latitude
  • Tag 24: Frame Center Longitude

The test passes when every claimed MISMMS packet carrying embedded VMTI preserves all three required parent metadata items.

The test fails when a claimed MISMMS packet contains Tag 74 but omits any of Tag 2, Tag 23, or Tag 24.

This rule complements the MISB ST 0903 embedded-VMTI cross-layer check by reporting the same parent/child dependency under MISB ST 0902 conformance.
