🗝️ Universal Key

The MISB ST 0601 Universal Key, also called the Universal Label, is the 16-byte key that identifies a UAS Datalink Local Set packet:

What This Test Does​

The Universal Key test is a stream-presence check.

For each declared KLV elementary stream, ST Inspector scans the carried payload bytes and looks for at least one fully decodable MISB ST 0601 packet with the expected Universal Key 06 0E 2B 34 02 0B 01 01 0E 01 03 01 01 00 00 00.
The test does not decide whether the stream is transported as ASYNC_KLV or SYNC_KLV; that transport-level consistency is handled by the separate KLV Type rule.

✅ Pass Criteria​

The test passes when each declared KLV stream contains at least one decodable MISB ST 0601 packet with the expected Universal Key.

❌ Fail Criteria​

The test fails when a declared KLV stream never produces a decodable MISB ST 0601 packet with the expected Universal Key.

Example​

A stream fails this test when the PID is declared as KLV but the payload never yields a decodable MISB ST 0601 packet. Typical causes include a corrupted Universal Key, truncated packet framing, or a non-MISB payload carried on a PID that was declared as KLV.
