| Abstract:
In the domain of missile applications, the integration of the Global Positioning System (GPS) technology has proven pivotal in improving the accuracy and reliability of Inertial Navigation Systems (INS). Nevertheless, the susceptibility of GPS signals to blockage, particularly within adversarial operational theaters, presents a noteworthy challenge. This paper presents a novel approach to enhance the precision of Inertial Navigation System (INS) solutions when GPS signals are unavailable. The proposed method integrates a seeker for Line of Sight (LOS) angle, an RF data link for range information, and a radar altimeter for measuring the distance between the missile and the ground. Combining these technologies makes the INS solution accurate even during GPS signal unavailability. The proposed approach capitalizes on the utilization of three supplementary data sources: the seeker, responsible for providing the line-of-sight (LOS) angle, the RF data link, providing the range information between the missile and the platform, and the radar altimeter, providing the distance between the missile and the ground. The proposed methodology involves the integration of these three measurements with the INS framework with the help of the Extended Kalman Filter (EKF). One of the key advantages of this method is its ability to function independently of explicit landmark positioning. The effectiveness of the proposed approach is demonstrated through comprehensive simulation studies, revealing substantial improvements in the missile navigation accuracy and the targeting precision. This research underscores the potential significance of incorporating seeker, RF data link and radar altimeter measurements within the INS solution, offering enhanced guidance capabilities in scenarios where GPS signals may be malfunction, thereby contributing to the advancement of missile guidance technology in challenging operational environments.
