Up to the minute propagation reporting?  
by AI2IA on August 9, 2013 Mail this to a friend!
Looks to me like an attempt to eventually obtain real time propagation conditions rather than forecasts. This, in turn, would influence the selection of the frequencies and modes of operation.

Unmanned aircraft goes up, then minutes later or less, is followed by a carefully selected frequency or mode for a radar or other device that best matches the conditions.

The catch? How rapidly can conditions change?
