SkyTrax 3000 Dual Band ADS-B In for Part 25 Aircraft

The Ideal ADS-B In Solution for Part 25 Aircraft

The Avidyne SkyTrax 3000 is a dual-band ADS-B In system designed to add modern surveillance capabilities to Part 25 cockpits without expensive cockpit overhauls. The TSO-certified system delivers enhanced traffic alerting, comprehensive weather data, and future-ready ADS-B In capabilities—all without modifications to installed TCAS II, transponders, or existing cockpit displays.

Legacy TCAS II systems rely on transponder replies to estimate range and altitude, often leading to large protection volumes and unnecessary alerts. By contrast, ADS-B provides precise position, altitude, and velocity data, enabling more accurate and timely traffic advisories.

The SkyTrax 3000 combines TCAS II, 1090MHz and UAT ADS-B, as well as ATC’s secondary radar tracks uplinked via TIS-B to create a comprehensive traffic picture that extends coverage and alerting capability even below TCAS II minimum altitudes.

With its dual-band reception, SkyTrax 3000 detects all ADS-B equipped aircraft, whether transmitting on 1090MHz or 978MHz UAT, ensuring protection during low-altitude and approach operations, even where ground rebroadcast coverage (ADS-R) is limited. The improved data quality available via ADS-B allows for high-precision alerting even in the most congested airspaces, such as in the terminal environment, reducing nuisance alerts common with TCAS II.

Leveraging over 30 years of Avidyne surveillance expertise, SkyTrax 3000 integrates seamlessly with installed TCAS II, transponders, and displays, providing operators with a comprehensive, future-ready surveillance solution.
