- Space debris
- An area where parts of a spacecraft or rocket stage are expected to come down at sea, from a launch or a planned re-entry.
- Date-time group (DTG)
- A compact UTC timestamp — day, hour and minute followed by Z — such as 201500Z for the 20th at 15:00 UTC.
- Area bound by
- Introduces a list of positions that are the corners of an area — the polygon the warning applies to.
