AIS(AUTOMATIC IDENTIFICATION SYSTEM) REFERENCE STATION SYSTEM FOR PROVIDING COMPENSATED ERROR INFORMATION SERVICE TO THE SHIP BASED ON DGPS(DIFFERENTIAL GPS) SATELLITE ERROR INFORMATION
PURPOSE: An AIS(automatic identification system) reference station system is provided to secure the safe of ship navigation through minute determination computation.;CONSTITUTION: An AIS base station apparatus(150) transmits a wireless transmission signal to an AIS terminal. An AIS virtual reference station apparatus(110) is connected to a DGPS reference station transmitting satellite error information through a network, receives the satellite error information, creates compensated error information from the received satellite error information, and transmits to the AIS base station device.;COPYRIGHT KIPO 2011
