中国卫星电话来了,目前已实现我国领土与领海的全面覆盖

卫星电话是基于卫星通信系统来传输信息的通话器,相比传统的通信手段拥有更广泛的覆盖面积,几乎可以实现任意两点的通信。经过近两年的努力,中国电信首次面向商用市场放号,我国进入到卫星移动通信的“手机时代”,填补了国内自主移动通信系统的空白,打破依赖国外卫星移动通信服务的现状。天通卫星覆盖范围广,通信能力强,服务无盲区。

Satellite telephone is based on satellite communication system to transmit information. Compared with traditional communication means, it has a wider coverage area, and can almost achieve any two-point communication. After nearly two years of efforts, China Telecom has for the first time released signals to the commercial market. China has entered the "mobile phone era" of satellite mobile communication, filling the gap of domestic independent mobile communication system and breaking the status quo of relying on foreign satellite mobile communication services. Tiantong satellite has wide coverage, strong communication ability and no blind area.

目前,天通卫星移动通信系统已经实现对我国领土、领海的全面覆盖,可广泛应用于海洋渔业、应急救援等多个场景。在服务区内,用户可以使用话音、短信、数据通信及位置服务。除了手持电话外,还有车载终端、天通猫等多种终端类型,用户也可以通过自己的手机应用直接连接终端、实现卫星通信。目前,该系统由中国电信独家运营,号段为1740,用户在线上或部分线下营业厅可以申请办理。

At present, Tiantong satellite mobile communication system has achieved a comprehensive coverage of China's territory and territorial sea, which can be widely used in marine fisheries, emergency rescue and other scenarios. In the service area, users can use voice, SMS, data communication and location services. In addition to the handset, there are a variety of terminal types such as vehicle terminal, Tiantong cat, etc. users can also directly connect terminals and realize satellite communication through their own mobile phone applications. At present, the system is operated exclusively by China Telecom, with a signal section of 1740. Users can apply for handling online or part of offline business hall.

中国电信股份有限公司卫星通信分公司总经理吕俊俐介绍称:从2018年3月我们试商用截至今天,已经有了近3万用户。正式商用以后可以面向广大的用户,目前基本上年套餐费用是1000元一年,包含了750分钟时长的通话费。

Lu Junli, general manager of China Telecom Satellite Communications Branch, said: since March 2018, we have had trial commercial use, up to now, nearly 30000 users. After formal commercial use, it can be used for a wide range of users. At present, the basic package cost of the previous year is 1000 yuan a year, including the call fee of 750 minutes.

天通系统使用的卫星,是发射于2016年的“天通一号”卫星,这也是我国首颗移动通信卫星。2016年8月6日,天通一号卫星成功发射升空,这是我国卫星移动通信系统首发星。天通系统中卫星、芯片、终端均由国内研发生产,摆脱了我国用户长期对国外卫星移动通信服务的依赖,保障了用户的通信安全。

The satellite used by Tiantong system is the "tiantong-1" satellite launched in 2016, which is also the first mobile communication satellite in China. On August 6, 2016, tiantong-1 satellite was successfully launched, which is the first satellite of China's satellite mobile communication system. The satellite, chip and terminal in Tiantong system are all developed and produced in China, which can get rid of the long-term dependence of Chinese users on foreign satellite mobile communication services and guarantee the communication security of users.

在此前许多重大自然灾害的抗击过程中,天通系统都承担了应急通信保障任务。未来,这一系统还计划面向全球提供更广范围服务。

In the process of fighting many major natural disasters, Tiantong system has undertaken the task of emergency communication support. In the future, the system also plans to provide a wider range of services globally.

工业和信息化部信息通信管理局副局长隋静表示:要进一步加强天通系统基础设施建设,加大对天通国际业务的推广力度,打造优质服务,进入国际市场,服务“一带一路”建设。

Sui Jing, deputy director of the information and communications administration of the Ministry of industry and information technology, said: we must further strengthen the infrastructure construction of the Tiantong system, intensify the promotion of Tiantong international business, create quality services, enter the international market and serve the "one belt and one road" construction.

卫星电话优点缺点:

Advantages and disadvantages of satellite phone:

卫星通信同常用的电缆通信、微波通信等相比,优点缺点如下:

Compared with cable communication and microwave communication, satellite communication has the following advantages and disadvantages:

远:是指卫星通信的距离远。俗话说,“站的高,看的远”,同步通信卫星可以“看”到地球最大跨度达一万八千余公里。在这个覆盖区内的任意两点都可以通过卫星进行通信,而微波通信一般是50公里左右设一个中继站,一颗同步通信卫星的覆盖距离相当于三百多个微波中继站;

Far: refers to the distance of satellite communication. As the saying goes, "standing high, looking far", synchronous communication satellites can "see" the largest span of the earth up to 18000 kilometers. In this coverage area, any two points can be communicated by satellite, while the microwave communication is generally set with a relay station about 50 kilometers, and the coverage distance of a synchronous communication satellite is equivalent to more than 300 microwave relay stations;

多:指通信路数多、容量大。一颗现代通信卫星,可携带几个到几十个转发器,可提供几路电视和成千上万路通话器;

Multiple: refers to the number of communication channels and large capacity. A modern communication satellite can carry several to dozens of transponders, and can provide several channels of TV and thousands of channels of talkers;

好:指通信质量好、可靠性高。卫星通信的传输环节少,不受地理条件和气象的影响,可获得高质量的通信信号;

Good: good communication quality and high reliability. The transmission link of satellite communication is few, and it is not affected by geographical conditions and weather, so it can obtain high-quality communication signals;

活:指运用灵活、适应性强。它不仅可以实现陆地上任意两点间的通信,而且能实现船与船,船与岸上、空中与陆地之间的通信,它可以结成一个多方向、多点的立体通信网;

Living: flexible and adaptable. It can not only realize the communication between any two points on land, but also between ship and ship, ship and shore, air and land. It can form a multi-directional, multi-point three-dimensional communication network;

省:指成本低。在同样的容量、同样的距离下,卫星通信和其他的通信设备相比较,所耗的资金少,卫星通信系统的造价并不随通信距离的增加而提高,随着设计和工艺的成熟,成本还在降低;

Province: low cost. Under the same capacity and distance, compared with other communication equipment, the cost of satellite communication system is less. The cost of satellite communication system does not increase with the increase of communication distance. With the maturity of design and technology, the cost is still reduced;

高:指通信资费标准高于常用的电缆通信、微波通信,是其资费标准的十倍乃至几十倍;

High: it means that the standard of communication tariff is higher than that of cable communication and microwave communication, which is ten times or even dozens of times of its tariff standard;

差:指在大型建筑内或山体等物体遮盖住设备本身时通信信号无或闪烁不定;

Poor: no or flickering communication signal when the equipment itself is covered by large buildings or mountains;

慢:指在通话过程中有延时现象,导致接续不畅。

Slow: refers to the delay phenomenon in the call process, resulting in poor connection.
