Is there any consideration being given to using/displaying positionless data? For example, my plane has a Mode S transponder, but not ADS-B out (yet). I can tell when my antenna is picking up my aircraft, but not specifically where the plane is. However, I do know that it is somewhere within the coverage range of my station, so I know the general position. If not flying IFR, this is as good as the positioning will get.
Any thoughts to making this data available? (i.e. which station(s) can currently, or in the past, see the aircraft)?
