M-Code
M-Code is a highly secure and advanced GPS signal used by the U.S. military and authorized allies, designed to be more resistant to jamming and spoofing than standard GPS. It provides improved accuracy and reliability for military operations.
TECHNICAL DEFINITION
M-Code (Military Code) is an encrypted, spectrally efficient Global Positioning System (GPS) signal, broadcast from modernized GPS Block IIR-M, IIF, and III satellites, providing enhanced PNT (Positioning, Navigation, and Timing) capabilities for authorized military and government users with superior anti-jamming, anti-spoofing, and integrity features.
BACKGROUND
The Uniform Code of Military Justice (UCMJ) is the foundation of the system of military justice of the armed forces of the United States. The UCMJ was established by the United States Congress in accordance with their constitutional authority, per Article I Section 8 of the U.S. Constitution, which provides that "The Congress shall have Power. .. to make Rules for the Government and Regulation of the land and naval forces" of the United States.
