Title: Innovations of Charles Emil Frey
Introduction
Charles Emil Frey is an accomplished inventor based in Colony, TX (US). He holds a total of 2 patents that showcase his expertise in aerospace technology. His work primarily focuses on methods and systems for air-to-air aircraft ranging.
Latest Patents
Frey's latest patents include a "Method and apparatus for air-to-air aircraft ranging." This invention discloses a method for determining the range between two aircraft by comparing model data estimating the velocity and position of a target with actual flight path data received passively. The model data undergoes error measurement calculations and is adjusted to generate new model data that closely conforms to actual data. Another significant patent is the "Covert ranging method and system," which involves a method for covertly determining and predicting air-to-air target data. This system passively senses the target to produce a data set, which is then transformed and compared to a predicted data set to generate measurement errors. The system actively senses the target for a brief period to improve the accuracy of the data.
