ETSO-C190

ACTIVE AIRBORNE GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS)

1 Applicability

This ETSO gives the requirements for new models of Active Airborne Global Navigation Satellite System (GNSS) Antenna that are manufactured on or after the date of this ETSO must meet in order to be identified with the applicable ETSO marking.

This ETSO apply to equipment intended to receive and provide signals to global positioning system (GPS)/satellite based augmentation system (SBAS) sensors or systems of all operational classes, and GPS/ground based augmentation system (GBAS) sensors or systems that will provide flight path deviation commands to the pilot or autopilot. These standards do not address the use of the signals received through this antenna for other applications. GPS/SBAS receiver operational classes are defined in RTCA document DO229D 'Minimum Operational Performance Standards for Global Positioning System/Wide Area Augmentation System Airborne Equipment' dated December 13, 2006, Section 1.4.2.

Note: For Passive Airborne Global Navigation Satellite System (GNSS) Antenna, see ETSO-C144a
