Inmarsat Mobile Satellite Communication Technology
And the International Maritime Satellite Organization (INternational MARitime SATelliteorganization; Inmarsat) in late 2003 by the signing of the Declaration, the global voice communications and digital information will be expected to upgrade from the satellite to be delivered. The cooperation between the two means will be entering a No matter vessels in the open sea, in the 30000? High-flying aircraft, or even any one of the world?s human feet can tread upon the environment can be voice communications era. The future, by the International Maritime Satellite Organization-led broadband global area network system (broadband global area network system; BGAN) In addition to the European Space Agency?s technical support, but also to the European Space Agency on the BGAN system, 50% of the funds sponsorship.
? With the country?s economic development, information communication technology has become to improve the management level, and enhance the efficiency of the basic conditions for effective face of China?s vast economic imbalance caused by the small total area covered by conventional communication, service area differences and are subject to major problems affecting the natural situation, with comprehensive coverage of mobile satellite communications service no difference, stable, and reliable communication quality advantages of a conventional communications network available to complement and extend the powerful, including Inmarsat mobile satellite communication system 20 years of operations for its reliable, safe, technologically advanced, cost-effective and reasonable global mobile satellite communications industry recognized best choice.
First of all, reliable communication is a basic requirement. Inmarsat mobile satellite communications, as IMO (International Maritime Organization) designated for maritime distress and safety communications system for help, hormone known for its stable and reliable communications. The entire communications network to rely on five-synchronous orbit satellites, and is equipped with a backup satellite, to ensure 365 days, 24 hours / day business without disruption. Second, the security requirements. Inmarsat mobile satellite as an international business and public safety communications systems to provide users with reliable and transparent transmission channel, on the one hand to protect the smooth transmission of various information, on the other hand to meet the needs of the user encryption to ensure the freedom of uninterrupted communication. Inmarsat mobile satellite communications business continued to expand the root causes of the technical research and development of its excellent work. It is always tracking new technologies combined with industry?s need for dynamic new products and services, including telecommunications services in the transplant, and the integration of 3G, broadband and other aspects of the business meeting to go in the mobile satellite communications industry?s first end. In addition, the system according to the amount of talk time or communications billing, no monthly fees, one-way charges, charges at the level of total transport sector based on the amount of peak operation period varies, ?use more support, less a small branch do not expend ?great to meet the economic emergency communication requirements.

Beijing Marine Communication and Navigation for Inmarsat in China?s sole legitimate operators, construction and operation and maintenance only ground station in China ? Beijing station, for up to 15 years of service to maintain the system?s advanced technology, R & D value-added services to promote the Inmarsat mobile satellite system to become the largest user base in China, using the industry?s most extensive, most system application integration for mobile satellite communication network, in the following areas have achieved good results.
One, using Inmarsat-C satellite radio and navigation systems development, telemetry and data acquisition, vehicle fleet management, remote tracking and monitoring of business
Inmarsat-C system is a pure data communication system, in addition to ordinary telex, data, text, fax, communication and positioning system, according to C double-entry feature, water conservancy, energy, transportation logistics, ocean transportation, fisheries, marine and weather information research industry to develop a variety of application integration system: With a good water Rain Fade telemetry functions necessary to develop CSCADA data acquisition systems used in water industry, widely used in rivers, lakes, water level forecasting, the full replacement of the water level of the manual measurement, as The first line of digital water products; used in the energy sector on oil, gas pipeline monitoring the situation and realize the whole network of regular inspections, traffic control, to ensure the security situation along the route and automation; used in the exploration industry to realize the no man?s land and danger zone at any time the data extraction, to facilitate data access to ensure the accuracy of the results, but also to ensure the personal safety of exploration; developed CTrack moving target monitoring system, combined with electronic maps, GPS, GIS (geographic information system) function, used in the logistics industry, to achieve seamless worldwide mobile communications and surveillance targeting the management teams of the business on the one hand to ensure contact with the company, to help drivers to locate, understand the navigation information, the other companies or by regular Extraction of the team at any time the location and travel path of vehicle fleet monitoring the situation, the vehicle alarm or control vehicle, to ensure vehicle safety, the company can provide goods to customers information inquiry service conditions, and improve service grades; used in ocean shipping industry, has been as distress and safety information systems and fleet anti-terrorism system, essential equipment, but also can be fleet management and monitoring; using the integrated systems and electronic charts used in fisheries management, fishing vessels fishing areas on the implementation of monitoring, but also to Using enhanced EGC (data broadcasting) functions released fish, ocean currents, weather information bulletin to help fishermen raise income, the effective protection of life and safety; meteorological and oceanographic research departments are using Inmarsat-C system and the corresponding analysis device integration, to achieve the survey data collection and extraction.
Depending on company / sector circumstances, Beijing Marine Communication and Navigation Company offers different solutions to achieve these system functions: for government departments, large vehicle fleet company monitoring center in the headquarters building, the electronic chart / map and information control information integration, and the Beijing ground station line or Internet network connection, to provide proprietary software release orders and announcements, will feedback directly reflected in the electronic map, and appropriate (such as leaving the designated area, the direction is wrong, etc.) options (warning, alarm, control); also use MCN development CMail, C-SMS, C-IGW business of Email, SMS, fax forwarding, etc. designated phone free way of receiving information; for data acquisition, energy trade to increase the remote control software and data analysis device interface, can control the system and extract data analysis; and for small companies, Beijing Marine Communication and Navigation Company provides digital map has a vector site, the site can publish instructions , display data and other functions, will also support the mobile phone users to text message form of simple
