China-Brazil Earth Resources Satellite. China's first earth resources satellite, known as ZY-1, weighed 1,540 kilograms. Chief designer was Chen Yiyuan. The satellite, a joint project of China and Brazil, was designed to gather information on the environment, agriculture and urban planning through remote sensing images and data transmitted to China, Brazil and other countries. Planned lifetime was two years. The satellite circled the Earth 14 times a day and the groundtrack repeated after 26 days. By 23 February 2000 it had taken more than 20,000 high quality images. It was formally handed over for operational use on March 2 2000. The High Resolution CCD Camera had a resolution of 20 meters in the visible spectrum. The camera could point up to 32 degrees to either side of vertical, imaging the earth's surface stereoscopically. After 177 days the Wide Field Imager failed in early May 2000. Other devices, including the high resolution CCD camera, continue to work normally.
First Chinese military communications satellite. First of the Feng Huo series for secure digital data and voice tactical military communications. Stationed at 98 deg E. The first in a planned constellation of satellites to be launched through 2010. Positioned in geosynchronous orbit at 98 deg E in 2000. As of 5 September 2001 located at 98.03 deg E drifting at 0.005 deg W per day. As of 2007 Mar 10 located at 97.95E drifting at 0.009W degrees per day.
The ZY-2 (Ziyuan-2 ('Resource-2'), while disguised as a civilian earth monitoring system, was actually code-named Jianbing-3 and was China's first high-resolution military imaging satellite. The cover story of the official Xinhua news agency was that the civilian remote sensing system would be used primarily in territorial surveying, city planning, crop yield assessment, disaster monitoring and space science experimentation. However the satellite was placed at a much lower altitude than the ZY-1 satellite and US intelligence sources indicated that it was a photo-reconnaissance satellite for exclusively military purposes, such as targeting missiles at US and Taiwanese forces. The new satellite was believed to employ digital-imaging technology and to have a resolution of 2 m or less. The satellite was designed and built by the Chinese Academy of Space Technology and was developed indigenously. It was said to be more advanced than earlier sensing satellites and was expected to have an orbital life of two years. The camera provided more than three times the resolution of the ZY-1 earth resources satellite. The Zi Yuan 2 satellite may have used the CBERS Sino-Brazilian bus of the earlier ZY-1. However it was also said to be of new design and demonstrated the capability to maneuver in orbit, adjusting its orbit after launch. In October 2000 Chinese scientists denied that the ZY-2 satellite had a military mission. It was said to be a remote-sensing satellite equipped with CCD cameras and an infrared multispectral scanner that could only identify objects on the ground with a resolution of several dozen meters to 1 km.
China's first navigation satellite, developed by CAST/Beijing. The satellite, the first in the Beidou-1 constellation, was placed in an initial 195 x 41889 km x 25.0 deg orbit geostationary transfer orbit before entering its final geosynchornous orbit at around 05:00 GMT on November 6. Stationed at 140 deg E, still maintaining its position within 0.1 deg as of 2007. No longer in use as of 2009.
Second Beidou-1 geosynchronous navigation satellite. The CZ-3A rocket's third stage put Beidou in geostationary transfer orbit at around 16:42 GMT. The Beidou satellite was based on the DFH-3 comsat and had a mass of around 2200 kg including its FY-25 solid apogee motor. On December 25 Beidou was in a 190 x 41870 km x 25.0 deg transfer orbit. The launch of this second Beidou completed the prototype two-satellite navigational system which was to provide positional information for highway, railway and marine transportation. Positioned in geosynchronous orbit at 80 deg E, still maintaining its position within 0.1 deg as of 2007. Retired after launch of the Beidou-2 geosynchronous satellites in 2010.
JB-3 2 was nominally a Chinese (PRC) remote sensing satellite, although US intelligence sources indicated it had primarily an intelligence imaging mission. JB-3 2 was the name adopted by the USSPACECOM. Most news reports from China and elsewhere use different names: ZY-2B (acronym for ZiYuan-2B, translated as Resource-2B), and Zhong Guo Zi Yuan Er Hao, translated as China Resource 2. No information was available on the instruments onboard the JB-3 2, but officially it was intended 'for territorial survey, environment monitoring and protection, urban planning, crop yield assessment, disaster monitoring, and space scientific experiments'. The initial orbital parameters of this sun-synchronous satellite were period 94.1 min, apogee 483 km, perigee 470 km, and inclination 97.4°.
Military communications satellite, launched to replace Zhongxing 22 in geosynchronous orbit at 98.0 E. Part of the Feng Huo series for secure digital data and voice tactical military communications. As of 2007 Mar 10 located at 98.10E drifting at 0.006W degrees per day.
