Latest Patents

Hepner's latest patents include a "Method and system for determining magnetic attitude," which involves deriving the attitude of a body as it rotates through the Earth's magnetic field. This system utilizes at least one magnetometer placed within the body to provide output signals during flight. The zero crossings of these signals are analyzed to formulate a time discriminant, which is then compared with a previously determined roll angle discriminant to ascertain the attitude during flight. Additionally, he has developed a "Method and system for determining the pointing direction of a body in flight." This method employs a solar sensor array and a magnetometer sensor array to calculate the orientation of a spinning projectile, allowing for the determination of its pointing direction through vector combination.
