The Comparison Study on AIS Signal Reception Rate with Directional Antenna and Omni Antenna
Journal Title: TransNav, the International Journal on Marine Navigation and Safety of Sea Transportation - Year 2016, Vol 10, Issue 2
Abstract
With the wide use of AIS system in the world, especially in ports and the waters with heavy traffic, AIS message loss may be related to environmental conditions, obstacle, limitation of VHF technology and AIS network overload, thereby reducing the AIS signal successful reception rate. This paper selected typical AIS data received by Yagi and Omni antennas at the same time in specific waters, uses grid and AIS data recovery technology, establishes the AIS signal coverage model, analyzes signal reception rate of Yagi antenna and Omni antenna of AIS base station, and verified the superiority of Yagi antenna in AIS signal reception rate.
