AtoN AIS using FATDMA Transmission Type (e-AIS AtoN 01)
If the traffic share of AIS exceeds 50%, there may be a problem in AIS communication. Therefore, IALA recommends that the AIS for route marking use FATDMA transmission methed.
※IALA Recommendation A-124 APPENDIX 14'FATDMA Planning and Operation of an AIS Service'
For pteventing AIS from reducing date transmission function, ITU recommends operating in FATDMA mode by ITU-R M.1371 recommemdation.
※FATDMA(Fixed-Access Time-Division Multiple Access):Multiple AtoNs use the same Slot repeatedly to increase the availability of AIS VDLS and prevent data collisions on scheduled SLOT to provide route marker information of intefrity for operating ships.
e-AIS AtoN route signs adopts FATDMA communication in compliance with the standatds of IMO, IEC, ITU and IALA.
Broadcasting of aids-to-navigation(AtoN) identification date on Message 21, as well as basic date and operating status
- MMSI identification
- Longitude, Latitude
- Signalling Light on off indicators
Able to transmit meteorological and oceanographic date on Message 8 (according to user requirenents)
Ideal for remote monitoring and control of beacons, providing alarms and status on Message 6 (according to user requirements)
Manutactured according to international regulations(IALA A-126, ITU-R M.1371-5, IEC 60945, IEC 61108-1, IEC 61162-1/2, IEC 62320-2)
