THW / FireThe named second layer. Longer sensors, stronger interceptors, same four messages. This is the first serious conversation, not the ministry.
TAK / CoTCursor on Target. The boring US/NATO-adjacent picture format that already moves tracks between phones, ATAK, WinTAK. A DETECTION can become a CoT point without inventing a new religion.
ASTERIXEurocontrol ATM surveillance. A later adapter, for when a cell must look like a radar to civil aviation.
DFS / BNetzAAirspace and spectrum. A roof radio is still a radio. The Scanner starts as a listener. Transmitters (RID on our test bird, later intercept C2) need a clean story.
BSISupply chain and node trust. Signed messages in the protocol are the technical half. The other half is who is allowed to flash the box.
Bundeswehr / NATONNbS, qualified C-UAS, Link 16 stays behind their door. We do not invent a private tactical data link. We speak DETECTION and, if asked, CoT.
