Descriptions
This paper aims to develop of a prototype communication base station (for coastal and vessel use) and carry out a field-based validation testing. In the prototype development phase, we create specifications and develop prototype communication base stations based on VDES/AIS international standards and guidelines. Subsequently, in the field validation phase, experiments will be conducted to collect propagation characteristics of VHF-band radio waves, which are essential for operational testing at the VDES experimental station currently under application. To achieve this, propagation tests will be conducted using VHF-band radio waves from existing AIS base stations. These tests will focus particularly on examining the propagation distance of the radio waves and the impact of obstacles. Additionally, as part of another validation effort, we measure the electrical characteristics (VDES-designated frequency, occupied bandwidth, and output power) of the prototypes in a simplified anechoic chamber.
