NAWCAD-FAA GPS Antenna Request for Information (RFI)

The Federal Aviation Administration (FAA) issued a Safety Alert for Operations (SAFO) (# 24002) on January 1, 2024, that provided information and guidance to operators and manufacturers regarding operations in a Global Positioning System (GPS) / Global Navigation Satellite System (GNSS) disrupted environment. This SAFO highlights ongoing jamming and spoofing incidents that can increase safety of flight risks due to possible loss of situational awareness and increased pilot and Air Traffic Control workload.

The FAA has requested support from the Naval Air Warfare Center Aircraft Division (NAWCAD) to investigate the feasibility and expected performance of applying anti-jam (AJ)/anti-spoofing (AS) GPS/GNSS technology for use in civilian aircraft applications with an initial focus on Transport and Business Jet aircraft. NAWCAD is releasing this RFI on AJ/AS GPS/GNSS technologies for eventual use in civilian aircraft applications. This RFI is a study identifying and discussing the characteristics and performance of the vendors’ AJ and AS antenna technologies that are currently available or being developed. The information learned from this RFI may be used to identify potential systems for evaluation testing at NAWCAD. Results from the RFI data and future evaluation testing will be used to develop updated GPS/GNSS AJ/AS antenna Minimum Operational Performance Standards (MOPS) and cockpit displays/annunciation MOPS for the FAA.

NAWCAD is performing the study, hosting the industry day(s), and establishing Cooperative Research and Development Agreements (CRADAs) or technology agreements for test hardware, lab test, chamber test, and future flight test for the FAA.

Questions related to the RFI may be issued through April 25, 2025.

Responses to the RFI must be issued by May 26, 2025 5:00PM Eastern Time
