What U.S. Department of Defense (DoD) and defense contractor research or programs address assured positioning, navigation, and timing (APNT)?

The U.S. Armed Forces have become reliant on the Global Positioning System (GPS) for precision navigation for foot mobile infantry to high-end precision weapons. Assured positioning, navigation, and timing (APNT) is defined as the ability to provide operational forces continuous access to position, velocity, attitude, and time information with confirmed integrity and sufficient accuracy to perform their mission under the complete range of threat conditions. Threat conditions include, but are not limited to, GPS degradation, denial, and deception. This report examines several aspects of APNT and its threats and describes many of the ongoing APNT programs within the U.S. Department of Defense and several of the major defense contractors’ research and development projects.
