Scientists continue to search for new technologies to serve the positioning, navigation, and timing (PNT) mission. One novel way to augment GPS comes from a newly developed technology involving a quantum magnetometer. Researchers at Lockheed Martin call it Dark Ice; it uses magnetic sensing as an alternative means of determining location without use of satellite
Defense Advanced Research Projects Agency (DARPA) is presently working on an advanced version of its first-generation, battery-powered, miniature chip-scale atomic clock (CSAC) with 1000x performance improvements for positioning, navigation, and timing (PNT) applications. DARPA’s Atomic Clock with Enhanced Stability (ACES) program aims to build the next-generation atomic clock owing to the limitations of the now
Russia and China have been increasingly moving toward greater synergies between their respective satellite navigation systems since at least 2015. The stated goals of the two powers have been ensuring compatibility and interoperability of GLONASS and BeiDou navigation systems; augmentations, including mutual allocation of measuring stations within the territories of Russia and China; global navigation
