379:, Inmarsat-2. These satellites provided the Inmarsat-A service for maritime uses. Between 1996 and 1998 Inmarsat's second constellation, Inmarsat-3, was launched. Consisting of five geostationary L-band satellites the constellation provides the Inmarsat-B and Inmarsat-C services, primarily providing low bandwidth communications and safety services for global shipping. Following privatisation in 1999 Inmarsat developed and launched the first satellite communications system offering global coverage, BGAN. This service was provided initially through the three Inmarsat-4 satellite launched between 2005 and 2008, and was then extended with the addition of 1504:: Since 2015, Inmarsat has offered high throughput services through the Global Xpress network. This service provides an IP based global service of up to 50 Mbit/s downlink and 5 Mbit/s uplink at a latency of 700 ms. Services are provided for maritime, aviation, government and enterprise markets. Global Xpress is supported by the existing BGAN L-band network, and services are offered using a combination of the two networks to increase availability and reliability. In March 2018, Inmarsat partnered with Isotropic Systems to develop all-electronic scanning antenna intended to be used with the Global Xpress network. 4726: 177: 1484: 1624:: IsatData Pro is a global satellite data service designed for two-way text and data communications to remote assets with message size to mobile: 10 KB / from mobile: 6.4 KB with typical delivery time of 15 seconds.

codes vary, depending on the country in which they are placed. Inmarsat primarily uses country code 870 (see below). Newer Inmarsat services use an IP technology that features an always-on capability where the users are only charged for the amount of data they send and receive, rather than the length of time they are connected. In addition to its own satellites, Inmarsat has a collaboration agreement with
