1 インドネシア海岸局 4 次プロジェクト Maritime Telecommunication System Development Project(IV) for Republic of Indonesia 若園徹高橋明彦有田勤 Toru Wakazono Akihiko Takahashi Tsutomu Arita 要旨 1983 JICA Japan International Cooperation Agency SAR Search And Rescue AIS Automatic Identification System 46 MF HF VHF AIS Abstract JRC has undertaken 5 large scale coast station projects based on the Indonesia Coast Radio Station Master Plan formulated by JICA (Japan International Cooperation Agency) over 23 year span: 1st stage project in 1986, 2nd stage project, SAR (Search and Rescue) project, 3rd stage project, and Remaining project of 3rd project in The present 4th stage project, the large scale project developing in 46 cites over all Indonesia as the culmination of previous projects, is primarily based on expanding upon and refurbishing the facilities which have been developed, complete refurbishment of small-scale local stations, and the introduction of AIS (Automatic Identification System). The primary equipment configuration of each station is as follows: the coast station system for communicating with ship station mainly based on MF, HF, and VHF radio equipments, multiplex radio equipments, AIS, training facilities, and maintenance facilities. In addition to those equipments, installation work is also to be provided as full turnkey contract. 1. はじめに 5000kmGMT+7 GMT+8GMT ,000 MF/HF/ VHF 2006 JBIC Japan Bank for International Cooperation JV Joint Venture 1.1 海岸局 25 VHF 150 MF HF MF/HF 1 2 日本無線技報 No
