The China Orient Telecommunications Satellite Company (COTS) was formed in April 1995 by the the Ministry of Post and Telecommunications [MPT] and the State Planning Commission. With the increasing separation of administration from business operations, accellerated by the merger of MPT into the new Ministry of Information Industry, China Orient had considerable autonomy in satellite operations.

The establishment of China Orient Telecomm Satellite Company, Ltd. was to keep in line with the national reform and open policy and accelerate the fast development of satellite telecommunication. With the approval of the State Council, China Orient was initiated mainly by the former Ministry of Posts and Telecommunications(the former MPT), and jointly by domestic investments, registered with the State Administration of Industry and Commerce on April 22, 1995. Now China Orient is functioning under the administration of the Ministry of Information Industry. Since February 20, 1998, according to the decision by the former MPT, shares held by the former MPT were transferred to the Directorate General of Telecommunications P&T of China(China Telecom).

On 18 August 1995 China Orient Telecomm issued a $100-million contract to Lockheed Martin for ChinaStar-1, plus an option for ChinaStar-2. ChinaStar-1, a high-power, high-capacity communications satellite based on the Lockheed Martin A2100 platform, was launched on 30 May 1998 by a Chinese Long March 3B launch vehicle. The 2,984 kg ChinaStar-1 has 24 C-band and 24 Ku-band transponders with a design lifetime of 15 years. From its location in geostationary orbit at 87.5 degrees East longitude, ChinaStar-1 provides coverage of China and Southeast Asian countries in both C- and Ku-band, and part of South Asia and Middle East (C-band only).

With 24 equivalent 36MHz band-width transponders for C-Band and Ku-Band respectively, the predicted life of "ChinaStar-1" satellite is over 15 years. The commercial communication satellite bus of the 21st century is newly designed by Lockheed Martin Corporation , with characteristics of modularization design , high reliability, great degree of intelligence , convenient and flexible operation for TT&C , high power , high receiving sensitivity, and being capable to support varied communication service. "ChinaStar-1" satellite can cover China , South , West , East, Central , and Southeast Asia , with its main task as to ensure the post and telecommunication public network communication , VSAT private network communication for major ministries and commissions and big corporations , broadcast and TV service , solve communication difficulties in remote areas, and provide neighboring countries with communication service.

The result of in-orbit test of "ChinaStar-1" shows that the satellite performance fully meets the Contract Specification. The use of the satellite will provide customers at home and abroad high quality space segment resource and play an important role in promoting the development of satellite communication in China and Asia-Pacific region. The satellite, which can cover China and most of Asia, has established and expanded domestic trunk lines and regional telecommunications services as well as private network satellite services.

China Orient Telecomm Satellite Co, whose ChinaStar-1 went into operation in 1998, has its sights fixed on both the heavens and the earth. The 5-year-old company will continue to build a team to track and control the telecommunications satellite while expanding its Chinese transponder market, a senior company executive said June 22, 2000. A transponder receives and retransmits radio-type signals. "The ChinaStar-1 has performed well since it was placed into orbit on May 30, 1998," said Hao Weimin, president of China Orient, in an interview with China Daily. "It has weathered dramatic outer space environmental changes, such as meteor showers and eclipses," he said.

China Orient had planned to purchase ChinaStar-2 and ChinaStar-3, though launch dates and technical information had not been made public, and it seems nothing came of these plans.
