![]() Not to mention that it will be in addition to and a complement the AIM-260 and not as a replacement for it. These are serious upgrades for a weapon that has an established supply chain, logistical base and is integrated on wide number of platforms. Separately, they are working on the AXE which will have the AMRAAM-ER booster, and additional optimizations around the motor and CAS. They are optimizing trajectory and adding more accuracy via enhancements to the initially fielded GPS. They aren't seeking to get more range by "software" alone. The integrated design accounts for interactions between the target state estimator, the guidance law, and the autopilot during the design process. Thus these guidance laws are not only effective in and of themselves, but also provide a simple framework within which an integrated guidance and control design can be carried out. The guidance laws (1) are more compatible with the seeker measurements which are angular in nature, (2) do not require an estimate of time-to-go, (3) can be used to directly drive the skid-to-turn or bank-to-turn logic that produces autopilot input commands, (4) avoid actuator saturation through the real-time adjustment of a single parameter in each channel, and (5) are less sensitive to random errors. In contrast to proportional navigation (PRONAV), these algorithms command the achievement of angular acceleration instead of linear acceleration and there is a significant advantage in doing so. These guidance laws are the solutions of linear-quadratic regulator control problems and minimize deviations from the collision triangle over the entire period of homing flight, thereby indirectly minimizing miss distance. ![]() Abstract​Two new homing guidance laws, designated as proportional Guidance (PROGUIDE) and Augmented Proportional Guidance (Augmented PROGUIDE), have been developed for use against non-maneuvering and maneuvering targets, respectively.
