Description:

Equipped with 28 C-band, 16 Ku-band; business services, public voice and data services, broadcasting, direct-to-home; Eastern Europe, CIS, South and Southeast Asia, Africa, Middle East, Australia.
The satellite will help satisfy the rapidly growing demand of Russian telecommunication and broadcasting companies for satellite capacity. The spacecraft is the first of several planned state-of-the-art satellites that are to provide connectivity to business and residential customers. In addition to its Russian coverage, LMI-1 is to deliver telecommunications services in the Commonwealth of Independent States, Eastern and Central Europe, Asia and Africa.
Hong Kong based Asia Broadcast Satellite (ABS), a newly-formed satellite operator, has acquired in September 2006 Lockheed Martin Space Communications Ventures (LMSCV) and Lockheed Martin Intersputnik (LMI) from Lockheed Martin Global Telecommunications (LMGT). As a result of the transaction, LMSCV and LMI have been renamed Asia Broadcast Satellite Holdings and Asia Broadcast Satellite, respectively. The LMI-1 satellite has also been renamed ABS-1. Capacity used by KT Telecom is referred as Koreasat 7.
