Accurate Time Tagging Unit News

EIVA announces the new SUBSEA version of its ATTU (Accurate Time Tagging Unit) for integration into subsea platforms such as ROV, AUVs etc. The EIVA ATTU adds high-precision time stamping across multiple sensor inputs – and thereby enables higher precision of the resulting surveys. For complex surveys, typically MBE, the off-shore industry has proven time tagging precision requirements beyond that which can be made on standard PCs. The rack version of the ATTU offers astonishing 50 microsecond guaranteed time tagging – many times better than the requirement and what standard PC / Windows implementations can offer. With the SUBSEA ATTU, we have put the ATTU electronics and software in a subsea housing for easy integration into ROVs, ROTVs, AUVs or other subsea platforms.
