GNSS antennas are significant contributors to GNSS aviation performance. This Working Group is tasked with the development of standards supporting Controlled Radiation Pattern Antenna (CRPA) technology. This new work will increase GNSS reliability and resilience when used in aircraft operations, while aiming at avoiding changes of receiver specifications. The WG will be reminded to speak strictly within ITAR rules.
The first deliverable of this Working Group will be an internal Report to ensure compliance with international export control regulations and to avoid any infringement of such regulations. CRPAs for PNT are proposed to be removed from the International Traffic in Arms Regulations (ITAR) list. Starting in September 2025, CRPAs should be reclassified under the less restrictive Export Administration Regulations (EAR) list, which is managed by the Department of Commerce.
The kick-off Meeting for WG-133 is scheduled for 6 June at the EUROCAE Offices in Paris, and is also open to non-members, who will be invited to join EUROCAE if they wish to continue their participation in the Working Group.
