Resilient GPS
Resilient GPS refers to systems and technologies that make the Global Positioning System more robust against intentional jamming, spoofing, and other forms of interference. This ensures that military forces and critical infrastructure can maintain accurate positioning, navigation, and timing (PNT) data even under attack.
TECHNICAL DEFINITION
Resilient GPS is a military and defense concept for assuring Positioning, Navigation, and Timing (PNT) services by hardening GPS receivers and space-segment assets against electronic warfare (EW) threats like jamming and spoofing, and cyber-attacks. It involves multi-layered solutions including advanced M-Code signals, anti-jam antennas (e.g., CRPA), multi-GNSS constellation receivers, and fusion with alternative navigation systems like Inertial Navigation Systems (INS) and celestial navigation.
BACKGROUND
The United States Armed Forces are the military forces of the United States. United States federal law establishes six armed forces: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard, each assigned specific roles and operational domains. With the exception of the Coast Guard, which operates under the Department of Homeland Security (DHS) in peacetime, the services are organized under the Department of Defense (DoD).

DEVELOPERS
Organizations developing technology related to Resilient GPS.
Develops advanced Military GPS User Equipment (MGUE), including the Digital GPS Anti-jam Receiver (DIGAR), which provides superior anti-jamming and anti-spoofing capabilities for airborne, shipborne, and ground-based military platforms.
A major provider of Assured Positioning, Navigation and Timing (PNT) solutions. They produce a wide range of resilient GPS technologies, including advanced anti-jam antennas, M-Code capable receivers, and integrated GPS/INS navigation systems for military forces.
As a subsidiary of RTX, Collins Aerospace is a primary developer of next-generation military GPS receivers. They are a leader in developing M-Code receivers, which are essential for the modernized, encrypted, and jam-resistant military GPS signal.
The prime contractor for the U.S. Space Force's GPS III and GPS IIIF satellites. These satellites form the backbone of GPS modernization, providing stronger signals, enhanced anti-jam capabilities, and broadcasting the secure M-Code, all of which are fundamental to resilient PNT.
The military service branch that operates, maintains, and modernizes the entire GPS constellation. It sets the requirements for resilient PNT and directs the development and acquisition of new satellites and ground control systems to counter emerging threats.
Develops alternative and complementary PNT technologies that enhance GPS resilience. This includes advanced Inertial Navigation Systems (INS), fiber-optic gyroscopes, and other sensor fusion technologies that allow military systems to navigate accurately when GPS is unavailable.
Operates federally funded research and development centers (FFRDCs) that provide systems engineering and research for the U.S. government. MITRE is deeply involved in testing GPS vulnerabilities and developing system-level strategies for ensuring PNT assurance and resilience against jamming and spoofing.
While known for commercial GPS, its Military & Advanced Systems division develops secure, ruggedized GPS receivers for military applications. They offer products with Selective Availability Anti-Spoofing Module (SAASM) and M-Code capabilities for precise and protected PNT.
