Latest Patents

One of his latest patents is titled "System and method for maintaining cooperative precision navigation and timing (PNT) across networked platforms in contested environments." This innovative system establishes and maintains precision relative position, navigation, and timing across a network of at least four mutually connected mobile platforms. The key node of the network determines its pressure altitude and inertial state relative to its platform reference frame. It exchanges data with neighboring nodes to estimate their relative positions and orientations. This method is particularly useful in GPS-denied areas, ensuring reliable navigation.

Another significant patent is "Time-critical obstacle avoidance path planning in uncertain environments." This system identifies safe paths in partially unknown environments in a time-critical manner. It involves identifying long-range paths that avoid known obstacles and breaking down short-range paths into segments. Each segment has corresponding abort procedures to ensure the availability of safe actions, enhancing the safety and efficiency of navigation in uncertain conditions.
