Another major function performed by this organization is radio determination services. Inmarsat is an international organization which works for the satellite system for the support of mobile communication system. The system can be consists as base for a GMDSS simulator. This center is able to manage messages received from Inmarsat terminal, via simulated satellite, and convert them into short text messages, automatically delivered to local network workstations, in faxes format or mail messages. The land earth station is software implemented in a PC linked with simulated satellite using a wireless network.
This satellite communication controller is linked with Inmarsat terminal via wireless transmission network and with another land earth station using a secondary wireless channel. The satellite functions are implemented into another embedded system controller. This controller transfer data to simulated Inmarsat satellite using a wireless transmission network. Compatible software, installed on embedded system controller is used for simulation of Inmarsat terminal. This communication channel implements Global Maritime Distress and Safety System and data transfer functions between INMARSAT-C compatible terminal and a land earth station. The establishment of mobile satellites is offering services to the public and commercial fleet operators the opportunity to take advantage of these developments. The use of satellites for control, command, communications and navigation is an area of high end technology which has grown significantly over the last decade and been primarily dominated by the military. This report is all about Inmarsat-c channels its standards and simulation of C channels using matlab.
