• ED Decision 2010/010/R found in: CS-ETSO Amdt 17 - European Technical Standard Orders (Oct 2026)

#### ETSO-C190 *ED Decision 2010/010/R* ##### **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 DO-229D “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](#_DxCrossRefBm920220863) **2 Procedures** 2.1 General Applicable procedures are detailed in CS-ETSO [Subpart A](#_DxCrossRefBm920220672). 2.2 Specific None **3 Technical Conditions** 3.1 Basic 3.1.1 Minimum Performance Standard Standards set forth in the RTCA document DO-301 “Minimum Operational Performance Standards for Global Navigation Satellite System (GNSS) Airborne Active Antenna Equipment for the L1 Frequency Band” dated December 13, 2006, Section 2. 3.1.2 Environmental Standard See CS-ETSO Subpart A paragraph 2.1 3.1.3 Computer Software See CS-ETSO Subpart A paragraph 2.2 3.1.4 Electronic Hardware Qualification. See CS-ETSO Subpart A paragraph 2.3 3.2 Specific 3.2.1 Failure Condition Classification See CS-ETSO Subpart A paragraph 2.4 Failure of the function defined in paragraphs 3.1.1 of this ETSO constitutes a loss of navigation which is a major failure condition. **4 Marking** 4.1 General Marking is detailed in CS-ETSO Subpart A paragraph 1.2 4.2 Specific None **5 Availability of Referenced Document** See CS-ETSO Subpart A paragraph 3 [Amdt ETSO/6]
