ADS-B From Garmin; Avidyne’s 430 Slide-In

As we go to press this month, Garmin is poised to announce a slew of new products at EAA AirVenture, including a new combined traffic/weather ADS-B box, a portable ADS-B receiver and updates to the established GTX 330 transponder. Not be left behind, Avidyne is right on Garmin’s heels—literally—with a new slide-in replacement for Garmin’s GNS430 mapcomms, the most populous navigator in the GA market. Garmin expects additional products later in the year. That ADS-B is where the current action is obvious from Garmin’s introduction of two products—the GDL88 and the GDL39 portable. The GDL88 is an ambitious product that’s a remote ADS-B transceiver capable of ADS-B in on both 978 and 1090 MHz and out on 978 with a low-power 1030 MHz transmitter for local traffic.
