Navigation Mark Design and Implementation Based on High-performance Radio Frequency Chip

With the popularization of automatic identification system (AIS), AIS has been widely used in the design of AIDS to navigation. In order to enlarge the working distance of AIS base station signal properly and send AIS message which meets the standard, an AIS navigation mark terminal based on high-performance radio frequency (RF) chip is designed. Through the design of local oscillator module and power amplifier module, it can compile and analyze the information of lamp, geographical position and hydrometeorological information received by sensor into three kinds of standard AIS messages, and send them to AIS base station and passing ships. The test results show that the new AIS beacon has a more stable high-quality RF signal and can send a variety of AIS messages, which proves that the new AIS beacon can achieve better navigation aid effect.

I. Introduction

Recent years witness extremely rapid application and development of AIS technology due to the broad prospects of AIS technology and people's demand for maritime safety. As an important navigation aid in the shipping industry, AIS has played a huge role in preventing ship collisions, coordinating maritime traffic management, and acquiring navigation mark information, which carries positive practical significance for ship navigation safety in navigable waters with dense ship flow ^[1]. As a navigation aid facility to secure safety, economy and navigation of ships, navigation mark also plays an important role in water transportation and marine resource development ^[2]. The application and popularization of AIS technology in navigation mark enables navigation mark to provide better navigation aid services for navigating ships, thereby avoiding possible navigation risks and achieving safer navigation.
