Thor Guard is the leader in lightning prediction and is committed to maximizing emergent technologies in the development of systems that provide automatic notification of hazardous weather conditions. Thor Guard uses a highly sophisticated sensor and computer to measure and analyze the electrostatic field in the atmosphere. Lightning originates within this field, thus allowing Thor Guard to make calculations predicting its occurrence even though there may be no visible evidence of lightning. Lightning detection systems require the occurrence of an actual lightning strike before a warning is given, and many such warnings are too late. For these reasons, multiple airlines, government agencies, and other industrial users are utilizing Thor Guard.
