Abstract:	Navigation and positioning technology is a prerequisite for the autonomous underwater vehicle (AUV) to carry out pre set tasks and safely return. Due to the constraints of the underwater environment, a widely adopted approach to achieve precise positioning of AUVs is through the combination of multiple navigation systems. This article focuses on the operational characteristics of AUVs and provides a detailed introduction to the features and technical challenges of acoustic velocity measurement systems, acoustic positioning systems, and geophysical field assisted navigation technologies. The latest development of multi source integrated navigation methods for underwater autonomous navigation is analyzed. It is worth noting that, with the recent advancements in relevant measurement instruments, geophysical field assisted navigation technology based on precise measurements of the Earth’s physical fields has emerged as a highly competitive solution. Furthermore, multi AUV cooperative navigation schemes are equally applicable to complex underwater environments and are considered as a significant development direction for future AUV navigation technology, which is extensively discussed in this article.
