GNSS antennas are significant contributors to GNSS aviation performance. This WG 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.
To do so the WG should consider that:

• The required level of performances already specified in existing GNSS antennas MOPS
should be considered and a new standard should be developed.

• The first task of the WG is to ensure compliance with international export control regulations
and to avoid any infringement of such regulations.

As of 17th January 2025, CRPAs for PNT will fall under much less restrictive export administration regulations (EAR) under the jurisdiction of the US Department of Commerce. In removing CRPAs for PNT, the US Department of States intends to facilitate civil global navigation system resiliency. The antennas removed from the U.S. Munitions List (USML) by these changes are neither subject to multilateral controls nor controlled as munitions in other countries that produce them. The change in US regulations will become effective as of Sept. 15th, 2025
