Drop point measurement precision is one of the core indexes to evaluate the combat effectiveness of weapons. With the development of experimental equipment, the experimental training venue has been expanded to the far sea. Due to the little known data in the far sea area and the measuring area, the measurement methods are limited. In response to the characteristics of the high seas, this paper proposes a method of mounts an optoelectronic pod on a drone and utilizes two drones for collaborative intersection measurement, achieving high-precision landing point measurement and high reliable data acquisition rate. This paper provides a detailed comparison between the traditional H-E-A single station angle measurement and distance measurement methods, the collinear equation based non ranging information positioning method, and the dual aircraft intersection positioning measurement principle combined with RLS filtering algorithm. At the same time, this paper analyzed various factors that affect the accuracy of positioning measurement. Through actual measurement verification of simulated targets, this method achieved a drop point measurement accuracy of 2m within a range of 3Km and a measurement accuracy of over 95%, which is significantly improved compared to traditional methods. The method provides data support for evaluating weapon effectiveness and obtaining field situation, and can also serve as auxiliary means for personnel search and rescue, debris search, etc., greatly improving the fusion ability of multidimensional data and enhancing the independent innovation and support ability of far sea measurement equipment.
