    • A stream cipher cryptosystem includes a pseudo-random bit generator receiving a key and providing a vulnerable keystream vulnerable to crytanalysis, and a non-linear filter cryptographic isolator to convert the vulnerable keystream into a protected keystream. The non-linear filter cryptographic isolator includes a multiplier for performing a multiplication function on the vulnerable keystream to provide a lower partial product array and an upper partial product array, and a simple unbiased operation (SUO) for combining the lower partial product array and the upper partial product array to provide the protected keystream. In example encryption operations, a plaintext binary data sequence is combined with the protected keystream to provide a ciphertext binary data sequence. In example decryption operations, a ciphertext binary data sequence is combined with the protected keystream to provide a plaintext binary data sequence.

    • An adhesive system for use in minimizing the negative environmental influences on a fiber optic gyroscope comprises a free-standing substantially cylindrical sensing coil (12) having an inner coil surface, a rigid substantially cylindrical coil-supporting structure or hub (10) having a cylindrical wall and an outer surface, a plurality of grooves (16) formed into the hub's outer surface, a plurality of slots (24) formed into the outer surface of hub (10) and an adhesive (14) affixing hub (10) to coil (12). Adhesive (14) may be injected into manifolds (18) located in the cylindrical wall of hub (10), travel through the slots (24) into a gap existing between coil (12) and hub (10). Excess adhesive (14) may flow into grooves (16). Different orientations and sizes of grooves (16) and slots (24), different types and amounts of adhesive (14), and different thicknesses of adhesive between the coil (12) and hub (10) may be used to achieve suitable adhesion. The adhesive system may further include a stress buffer (22) and an additional adhesive (20) to further minimize environmental influences on coil (12). Specifically, a first adhesive (14) affixes the inner surface of buffer (22) to the outer surface of hub (10). A second adhesive (20) affixes the outer surface of buffer (22) to the inner surface of coil (12).

    • For accuracy and reliability reasons, GPS systems have traditionally not been used for critical phases of aircraft navigation and guidance, such as aircraft landings. Accordingly, the inventor devised a ground-augmented GPS system that incorporates a better method for determining the accuracy of its position solution. One exemplary embodiment determines a main position solution and one or more position subsolutions, with the main solution using all broadcast correction data and each subsolution using a respective subset of the correction data. Differences or separations between the main position solution and the subsolution are then used to determine accuracy, or protection, limits for the main position solution. Another embodiment uses Kalman filters to incorporate vehicle motion data into the calculation of the main solution and the subsolutions, enabling the determination of protection limits during periods lost GPS or correction data.
    • 出于准确性和可靠性的原因,GPS系统传统上不用于航空器导航和指导的关键阶段,例如飞机着陆。 因此,发明人设计了一种地面增强的GPS系统,其包括用于确定其位置解决方案的准确性的更好的方法。 一个示例性实施例确定主要位置解决方案和一个或多个位置子解决方案,其中主要解决方案使用所有广播校正数据,并且每个子处理使用校正数据的相应子集。 然后使用主位置溶液和下沉之间的差异或分离来确定主要位置解决方案的精度或保护限值。 另一实施例使用卡尔曼滤波器将车辆运动数据并入到主解决方案和子解决方案的计算中,使得能够在丢失GPS或校正数据期间确定保护限制。
