Brief introduction of the three major satellite phone products


What is a satellite phone?

Satellite phones are interphones that transmit information based on satellite communication systems. Satellite phone is the product of modern mobile communication. Its main function is to fill the area that cannot be covered by existing communication (wired communication, wireless communication) terminals, and provide more complete communication guarantee for work and life. In modern communications, satellite communications cannot be replaced by other communication methods, and all communication functions provided by existing commonly used communications have been applied in satellite communications.

What are the characteristics of satellite phones?

Satellite phones have four main features: First, seamless coverage. The use of satellite mobile communication can not be limited by the ground communication base station, and can still ensure effective communication capabilities even when the traditional communication equipment cannot use the signal. Second, the battery life is long and durable. Satellite phones are designed to be simple and durable. Taking the handheld satellite phone Shulaya XT-LITE as an example, the continuous talk time can usually reach 6 hours after one-time charging, and the standby time can reach at least 80 hours when the satellite signal is connected. Third, high confidentiality. Fourth, safety and reliability. Satellite phone signal transmission does not rely on ground base stations and line facilities, so when the ground communication network fails due to geological disasters, man-made damage and other factors, satellite communication is an unparalleled important communication means.

Third, compare the world's three major satellite phone operators

(1) Thuraya Thuraya (Eurostar) is a global commercial satellite communications system operated by the UAE Shuraya Satellite Company, with its headquarters in Abu Dhabi. The satellite system consists of 3 high-orbit satellites that are 36,000km away from the earth. At present, it covers about two-thirds of the earth in about 160 countries and regions except North and South Pole and North and South America. The tariff standard according to the calling area is less than RMB 2 per minute. It is the most cost-effective satellite communication option in China. Features: good signal, fast star search, light and durable, low cost, flexible and cost-effective. Disadvantages: No signal in North and South, North and South America.

66 颗卫星组成。 (2) Iridium Iridium mobile communication system is a global satellite mobile communication system designed by Motorola Corporation entrusted by Iridium Corporation of the United States. It belongs to a low-orbit satellite communication system. composition. Five "Any" (5W) are realized, that is, anyone (Whoever) communicates with anyone (Whomever) in any way (Weverever) at any time (Whenever). Satellite communication systems with truly global coverage are also globally recognized satellite communication systems with good performance. Features: low orbit, fast star search and transmission speed, and low signal attenuation; the only full-coverage satellite communication system in the world (including North and South Pole). Disadvantages: High tariffs.

(3) Maritime Satellite Maritime Satellite The Inmarsat communication system was formerly the International Maritime Organization (IMO). It considers the use of satellites to provide ships with reliable maritime distress safety and business communications. It is mainly used for maritime operations. Maritime satellite Inmarsat communication system is an earlier satellite communication system introduced in China. Advantages: Covering global regions except North and South Pole, the maritime operation expansion function is powerful. Disadvantages: The communication quality in mainland China is weak.
