GARMIN® GTX™ 330/330 ES...
GARMIN® GTX™ transponder product line includes Mode A/C and Mode S TSO'd panel mounted transponders offered in a wide variety of configurations to choose from, depending on desired functions. Different models are listed under separate product presentations.
GARMIN® GTX™ 330 is a panel-mounted IFR-certified 250 W, Mode S digital transponder with traffic datalink capability and dedicated pushbutton keys for squawk code selection. The GTX™ 330 series brings ATC aircraft surveillance to new levels of precision, reliability and performance. Optionally available with 1090 MHz extended squitter transmission, certified to TSO-C166b authorization, the GTX™ 330 ES (Extended Squitter) provides an affordable pathway to ADS-B compliance for the Next Generation airspace system. The extended squitter technology enables transponders to automatically transmit traffic surveillance data (including aircraft flight ID, position, altitude, velocity, climb/descent, and heading information) compared to traditional Mode S and Mode C transponders, which can only broadcast altitude, and thus require a ground-based radar to correlate and identify the aircraft's position. In addition, simultaneous broadcast of this information to TAS or TCAS equipped aircraft, enables them to essentially see the same traffic picture for their location that ATC is watching on the ground. The “ES” upgrade provides a ADS-B Out solution but an input from an approved position source is still needed as GTX™ 330 does not have a WAAS GPS.
GARMIN® GTX™ 330 is discontinued and replaced by GTX™ 335, an entry-level ADS-B Out model with a version integrating an internal WAAS GPS. If ADS-B In capability is required then the the GTX™ 345 transponder should be selected.
