uAvionix is working on a wingtip ADS-B Out device that will work with satellite-based ADS-B systems that will be used in several countries and the U.S. system, which relies on ground stations. The skyBeacon X will pack upward and downward pointing antennas into a compact integrated device that will also replace a wingtip position light. The development project was spurred by contact from Canadian pilots who could be required to install ADS-B Out as early as 2023. Nav Canada, the not-for-profit corporation that supplies air traffic services in Canada, will use the Aireon satellite system for ADS-B surveillance and that requires antennas pointed skyward. Most ADS-B systems now available for GA aircraft are designed for the U.S. terrestrial system and the few that do offer the so-called antenna diversity required in Canada are significantly more expensive. uAvionix hopes to have the system ready for sale in 2021.
