The Difference Between GMT and UTC

Greenwich Mean Time (GMT) is often interchanged or confused with Coordinated Universal Time (UTC). But GMT is a time zone and UTC is a time standard.

GMT is a time zone officially used in some European and African countries. The time can be displayed using both the 24-hour format (0 – 24) or the 12-hour format (1 – 12 am/pm).
UTC is not a time zone, but a time standard that is the basis for civil time and time zones worldwide. This means that no country or territory officially uses UTC as a local time.

The ALT-8000 is a universal test set for 4.3 GHz FMCW (frequency modulated continuous carrier wave) radio altimeters and pulse radio altimeters.
