What This ECCN Covers

ECCN 7A008 controls underwater sonar navigation systems using Doppler velocity or correlation velocity logs integrated with a heading source and meeting the positioning-accuracy criteria in the entry. These systems let submersibles and survey vessels navigate without surface references, and are controlled for National Security and Anti-Terrorism reasons.

Who needs to check this?

Makers and exporters of Doppler velocity logs and underwater acoustic navigation systems for ROVs, AUVs, and survey vessels.

Compliance tip

Control turns on the integration and accuracy parameters in the entry — simpler depth sounders or standalone logs may fall outside. With NS among the reasons, verify the Country Chart and screen the end use before relying on a license exception.
