The LFMG with its extremely high sensitivity and stability will have a variety of commercial and military applications. including measurement of the magnetic fields at the Earth's surface for geophysical airborne and marine prospecting. The LFMG can serve as the new standard for geomagnetic observatories. The LFMG instruments can be used to investigate surface and magnetospheric effects before and after earthquakes and volcanic activity. The LFMG can technology can be used in the next generation high-sensitivity magnetometers to be used by the US Navy for submarine detection and mine countermeasures applications. The LFMG instruments will add high resolution ELF capability for solving DoD magnetic detection problems. The miniaturized LFMG sensor will have applications in UAVs used for sea and land surveillance for submarines, tanks under trees, tunnels, and underground facilities. The LFMG characteristics of outstanding accuracy and high-frequency signal response will open up a variety of applications in commercial security and surveillance applications. The accurate measurement of the magnetic field components and their orientation in space is recognized as a basic requirement for space research. The LFMG will be used to observe magnetic fields at the Earth¬Åfs surface with extremely high resolution. The major features of the LFMG that set it apart from other magnetic measurement systems are its outstanding accuracy and its ability to difference scalar measurements at many kilometers separation. LFMG magnetic field measurements provide means for studying the structure and dynamics of Earth¬Åfs interior. On the Earth and other planets, the magnetic field provides unique information on the structure and dynamics of the planetary interior, fluid flow within and upon its surface, and the influence of the solar environment. The LFMG can be used for extremely high resolution investigations of geopotential changes in the Earth¬Åfs crust associated with earthquakes and volcanic activity and eruptions.
