Calls from Inmarsat Mini-M or Inmarsat M4 satellite phones that support satellite telephone connection, are always carried out in the same way:

[ 0 0 ] [country code] [area code] [phone number] [#]

0 0 7 4 9 5 7 8 2 1 8 8 8 [#]

If you call another satellite phone Inmarsat, then the dialing form will be as follows:

[ 8 7 0] [Inmarsat satellite phone number] [#]

- How to call the Inmarsat satellite phone?

The dialing procedure in this case depends on where you are calling the Inmarsat phone from:

Call to Inmarsat satellite phone with cell phone.

In general, the dialing form is as follows:

+ [satellite phone number]

Depending on the cellular network and on the type of your contract with a cellular operator, calls to Inmarsat satellite phones can be made with or without a PIN code (see also the previous paragraph). If, after dialing the number, you are asked for a PIN code and you enter it, the owner of the PIN code will be billed for incoming call to the Inmarsat satellite phone. If your cellular operator connects you without a PIN, the operator will bill you for such a call, and for the owner of a satellite phone, this call will be free.

Wait for the response of the called terminal.

(There is a feature - you can first hear the call signal, and then the busy signal. This means that the terminal is busy).

From some commercial telephone networks calls to satellite phones can be made differently. We recommend that you contact your telephone service provider.

- How are calls charged in the Inmarsat satellite network?

When charging satellite communication services Inmarsat, the dependence of the cost of a conversation on its duration.M

Minimum call duration: 15 sec.

Call duration rounding step: 15 sec.

Connections lasting less than 3 seconds are not charged.

- Is the confidentiality of communications maintained when calling on Inmarsat satellite phones?

If you are an Inmarsat subscriber, then complete confidentiality of communication can be guaranteed when calling from one satellite phone to another. In this scenario, the signal does not pass through Russian public terrestrial networks, since all gateways are located abroad. When a connection is established between a satellite and a conventional wired (or cellular) telephone, the conversation can be intercepted by intruders who have connected to landline telephone networks. In this case, the confidentiality of the call can be ensured only with the help of a special encryption device - a scrambler.

- How accurate is the location of an Inmarsat satellite phone?

The location of the Mini-M and M4 satellite phones of the Inmarsat network can only be determined with an accuracy of the continent. Those. you can say, for example, that a satellite phone with such and such a number is located in Europe, or in South Africa. This information is available only to the technical staff of Inmarsat LES (overseas) and is not subject to disclosure. In the Inmarsat network, there is also user equipment with a built-in satellite navigation satellite receiver. GPS systems. For example, Inmarsat-C equipment, which does not support telephone communication and is intended for building dispatch control systems. The location of the Inmarsat-C terminal can be determined with an accuracy of 20 - 100 meters.

- What additional devices can I connect to my Inmarsat satellite phone?

Can be connected to satellite phones personal computers for data transmission and Internet access, fax machines, as well as conventional external phones or radiotelephones + smartphones.

Despite the widespread development cellular networks and great amount towers, which continues to grow, there are still territories on the planet where the use of such technology is impossible. In these inaccessible zones comes to the rescue satellite connection.

Satellite communication - what is it and what is it for?

In fact, nothing radically from the usual for society mobile communications satellite is no different, it performs the same functions, allows you to establish communication between phones. The main difference is the scope. Where a classic mobile (cellular) phone can fail and issue the ill-fated “No Service”, notifying the subscriber about the absence of a nearby honeycomb coverage, satellite communications will fully function and will not allow you to lose contact with the outside world.

This is extremely important in those moments when the subscriber goes beyond the limits of cellular coverage, for example, on an exotic trip, in the mountains or in the dense jungle. Often such a connection saves lives, because only through it it will be possible to contact a rescue team if a person unexpectedly finds himself in a dangerous situation. Also, satellite communications are used by those who are constantly traveling for work and vitally need the opportunity to receive or make a call at any time.

Satellite phone: main characteristics

To work with this type of communication, a special satellite phone is required. They come in several types, namely: stationary and mobile. Mobile satellite phones appearance reminiscent of classic phones released in the period of 80-90s, but they have one characteristic detail: almost always such phones are equipped with an additional, unhidden antenna. Setting up a satellite phone is almost the same as setting up regular phone All you need is a suitable SIM card.

Stationary variants communicate with the satellite using specialized ground interface stations. You can get by with a portable version of such a station.

A number of manufacturers of satellite phones and, accordingly, owners of satellite networks, produce special accessories for modern smartphones, which are small cases that can make absolutely any gadget satellite. These cases connect to smartphones using a standard charging port and have full set Peripherals inherent in smartphones, for example, headphone jacks. The covers are equipped with their own battery, they can charge a smartphone, that is, they act as a battery cover.

The principle of operation of satellite communications

Based on the name, it is clear that a satellite phone needs to be connected to a satellite in order to work. The satellite phone transmits the signal directly to the satellite, which, in turn, transmits it to another connecting satellite, and it already completes the process and transmits the signal to the ground gateway station. In the end, the call arrives at the stationary device, which closes the chain.

The satellite phone is capable of operating both within certain area, as well as throughout the Earth. It all depends on the satellites, some of them are close enough to the Earth and move relative to it, they allow you to cover the entire planet and make a call to any point. There are other types of satellites that are located relatively far from the globe, in geostationary orbits. Such satellites cover only specific locations, thereby limiting subscribers.

Satellite operators

In satellite communications, the same laws apply as in cellular, there are a number of operators providing satellite communications services. As a rule, these are the same companies that launch their satellites into space. Each of them has its own characteristics, pluses and minuses. On the this moment, there are four main satellite operators, including: Iridium, Thuraya, Globalstar and Inmarsat.

Operator "Iridium" and its devices

Iridium is not just an operator, but a full-fledged satellite constellation. It owns 66 satellites moving in 11 near-Earth orbits. The distance from the satellite to the earth is less than 1000 kilometers. For the user, this means that no matter where in the world he is, using the services given operator, he will always be in touch, the main thing is to be in the open air. Even if the connection failed when trying to connect, it is enough to wait some time and try again, since the satellites move fast enough, and one of them will definitely fly over the subscriber in the next 10 minutes.

The Iridium satellite phone does not support other SIM cards and cannot switch between cellular and satellite communications.

Also, many people find complete anonymity useful in the post-Soviet space. The Company does not have ground interface stations in Russia. This fact completely excludes the possibility of wiretapping within the country, even if special services take up this matter. Satellite phone "Iridium" is not equipped with a GPS module.

Thuraya operator and his devices

This operator has three satellites located in geostationary orbit. The distance between the satellite and the earth reaches 35 thousand kilometers. Unlike the Iridium satellites, these satellites only operate over a certain point near the equator, since they do not move relative to the planet. Roughly speaking, the Thuraya satellite phone does not function at the poles, the farther the subscriber moves away from the equator, the less likely it is to establish a connection.

Thuraya has entered into contracts with many "terrestrial" cellular operators, thanks to which, the company's devices can work with ordinary GSM-sim cards. This allows phones to automatically switch between different types connections. At the same time, the cost of the services of a cellular operator increases several times. At the same time, you can save on even more expensive satellite communications when there is no need for it. Thuraya phones provide Internet access at speeds up to 8 kilobytes per second, which is quite high rate for satellite internet. The devices are equipped with a GPS module and constantly transmit location data to the company's servers. On the one hand, this fact can be confusing, since the user is constantly being monitored, on the other hand, such a function can save the life of a negligent traveler and extreme lover.

Operator "Globalstar" and its devices

Perhaps the most problematic operator, providing no best quality connections. In 2007, analysts conducted a study and made sure that the amplifiers installed on satellites degrade over time, and much faster than the design engineers expected. The reason for this is the orbit of the satellites: they pass through the Brazilian magnetic anomaly, which has a negative effect on the amplifier.

In order to somehow correct their situation, Globalstar launched several spare satellites into orbit, but to this day there are problems with calls. Often, the waiting time for registration on the network reaches 15-20 minutes, and the conversation itself lasts no more than 3 minutes.

The company manufactures its own devices. For example, the Globalstar satellite phone of the same name. Also devices from Erricson and Qualcomm work in their network.

Operator "Inmarsat" and its devices

The company manages 11 satellites hovering in geostationary orbit. The communication provider is focused on professional use and provides communications to the security services, navy(including the Russian one, when domestic satellites went out of order) and so on. However, there are other business-oriented subsystems. Through a system of satellites, you can make voice calls, transmit data over the Internet and send distress signals. Not so long ago, a new generation of satellites were launched into orbit, providing high-quality communications and ISDN connections for data transmission at high speeds.

The company is not engaged in the development of portable solutions for ordinary people, therefore this is not the best choice for civilians looking for a satellite phone.

Tariffs

The cost of the services of the companies described above is much higher than the cost of GSM communication. Iridium and Thuraya work directly with their users by selling SIM cards for satellite phones.

Thuraya, for example, charges for the SIM card itself (about 800 rubles), for the initial connection (about 700 rubles). Communication is paid per minute, on average from 20 to 40 rubles, depending on which phone the call is made to. Internet traffic is paid separately - 360 rubles per megabyte. Tariffs for international communication depend on the country receiving the call, on average from 70 to 120 rubles. Incoming calls are free.

Iridium immediately offers global tariffs and sells them in prepaid packages. The price for the basic package is 7500 rubles, it includes 75 minutes of communication. There are other packages designed for corporate users, the number of minutes in those reaches 4000 or more.

Satellite phone numbers in Russia, like cell phones, start with +7 (location code) and a seven-digit number. International number includes the full country code - +8816 265 and so on.
