Therefore, most of the users of these devices large vessels. Inmarsat-A. Introduced in 1982 to telephone, fax, data, telex and mobile recharge offer e-mail offer. Inmarsat-B. Launched in 1993, is the digital successor to Inmarsat-A (which still works). It offers similar services to Inmarsat-A, but at lower prices online mobile recharge api thanks to the better spectral use. Inmarsat-C. Considered the first personal communications via satellite and one of the most popular. It lets you send data using portable terminals. Inmarsat-D. It is a paging service, so in one direction satellite. Inmarsat-E.

Used to alert maritime disasters service, combining the ability to communicate online mobile recharge api with the satellite positioning system with the aid of GPS-satellites. Inmarsat-M. The first personal portable satellite telephone transmission of voice, data, fax and the group's call for the size of a suitcase leaves from a terminal. The maritime version of the system provided with an antenna with a random of 70 cm in diameter.

Mini-M. Designed to exploit the capabilities of the new generation of Inmarsat-3 with low beam antennas (spot beam). It is the smallest online mobile recharge api terminals, having a size equal to that of a laptop (notebook). In this group are all new generations of satellites, which are scheduled for commercial launch between 1998 and 2001.

The main online mobile recharge api difference between MEO and LEO is the height of the orbit, and so plan in terms of the number of satellites required for a providing universal coverage and how to manage the network. That is closest to the earth satellites, facilitating the design smaller and consumes fewer terminals (lower distance implies lower gain antennas, lower radiated power and thus lower power consumption and smaller size of the required battery). Moreover, it is not necessary to increase the gain in the computer with the aid of directional antennas, can be used in a single direction antennas at the terminals, making them real personal mobility with respect to the more complex geostationary terminals. Then the four draft global systems most likely commercial systems are displayed.

It is based on a constellation of 66 satellites in low orbit (740 km) system, located in 11 polar surfaces, which aims to provide global coverage. The Iridium is regulated by a number of mobile recharge offer telemetry and control stations and communicates with terrestrial networks via a plurality of online mobile recharge api switching stations that are, in principle, to the GSM standard. Satellite phones communicate with the 1,6 GHz-band (L-band), and used as the TDMA access technique. The Iridium system is the only one capable of conversations between their own satellites, ie switch a call between the two terminals, Iridium does not switch by a terrestrial network to pass.
