Last year there were a handful of companies promoting devices that could capture weather and traffic signals from the growing network of ADS-B ground stations deployed around the U.S. This year, the market and the makers of ADS-B devices have exploded, and buyers now have an array of choices.
The good news is that these devices are now available for both Android and Apple devices. The even better news is that some manufacturers have added fairly significant capabilities to their ADS-B devices, although some of these have yet to begin deliveries.
