It wasn’t long ago that subscription-based satellite broadcast weather systems lost traction in a market flooded with ADS-B weather receivers. WSI is canceling its InFlight data service at the end of this year and Avidyne discontinued the MLB700 Sirius weather receiver. This leaves Garmin as the dominant supplier of SiriusXM (SXM) weather receivers.
While SXM’s longevity is anyone’s guess, Garmin finally brought the anticipated GDL51 and GDL52 to the market this past summer. There’s also the SiriusXM Aviation SXAR-1 (which is sold by Sporty’s and directly from SiriusXM), plus the WR-10BT WxWorx receiver that’s sold by Baron Weather.
