A Multi-mission Payload Unmanned Surface Vehicle System

In recent years, with the rapid development of science and technology towards information and intelligence, unmanned war mode is gradually becoming the new trend of future war development. In the unmanned system architecture, USV is an important cross domain node of air, ground, sea and submarine stereoscopic unmanned combat system, and has become the focus of research in various countries in recent years. Firstly, this paper introduces the domestic and foreign research status of USV system; Then, the composition and logic architecture of a multi-mission payload USV system proposed in this paper are introduced in detail; Finally, the sea experiment is conducted for the satellite navigation failure environment and sonar underwater target detection. The experimental results show that the positioning error can be kept below 0.138% for the satellite navigation failure environment(Using GPS positioning data on the evaluation system as the true value), and the false alarm rate can be reduced by 9.3% in the joint detection of underwater targets with forward looking and side scanning sonar.
