ACE?
- ACE stands for "Animated
Communications Effectiveness", a coverage display technique
originally developed for U.S. Navy submarine communications.
- The ACE method shows a
sequential series of coverage maps. When the maps are animated,
a movie is shown.
- ACE-HF's advantage is
that the effects of the day's passage may be easily understood.
ACE shows when the HF bands will be open in different world areas.
