Q

Sites that have CUDIXS suites and their capabilities?

A

NCTAMS PAC,
NCTAMS LANT,
NCTS Guam,
NCTS Naples

The two NCTAMS, NCTS GUAM, and NCTS Naples are equipped with CUDIXS. Each site has at least three CUDIXS suites and the capability to operate two full and one “mini” configuration simultaneously.
