The way we see it, portable and affordable ADS-B receivers are threatening—if not putting a sizable dent—in the once-dominant satellite broadcast weather market.

Even though the FAA’s free, ground-based FIS-B weather information stream isn’t exactly a match for XMWX products, many users we talk with are tired of paying the increasing costs of XM subscriptions. With pricing options that range from $35 to $100 per month, it’s easy to see the appeal of free ADS-B weather if you can accept some compromises, including the lack of reception while on the ground and the lower resolution of FIS-B radar.
