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.

Apogee: 501 km (311 mi). Perigee: 489 km (303 mi). Inclination: 97.4000 deg. Period: 94.43 min. 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.

2002 May 15 - . 01:50 GMT - . Launch Site: Taiyuan. Launch Complex: Taiyuan LC1. LV Family: CZ. Launch Vehicle: CZ-4B. LV Configuration: Chang Zheng 4B CZ4B-4 (67).

Apogee: 799 km (496 mi). Perigee: 785 km (487 mi). Inclination: 98.4000 deg. Period: 100.70 min. The HY-1 (Haiyang-1) marine observation satellite separated shortly after the FY-1D. The 360 kg HY-1 was based on the SJ-5 bus and carried an IR radiometer and CCD imager for oceanographic studies. Between May 21 and May 26, HY-1 lowered its orbit to 793 x 799 km using on-board propulsion.

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'.

Chuangxin-1 (or Innovation-1) was China's first experimental small satellite for store-and-forward short message data communications in low Earth orbit. With a mass less than 100 kg, the Chuangxin-1 was developed in light of national strategic demands. Starting from 1999 with support of the national Knowledge Innovation Program of the Chinese Academy of Sciences (CAS), the project was carried out jointly by researchers from the CAS Shanghai Institute of Microsystem Information Technology and the CAS Shanghai Institute of Technical Physics. The satellite used spread spectrum communication and subsystems included a communication transponder, onboard computer, attitude control, energy source, thermal control, and structure. The mission was to demonstrate data communications for such sectors as traffic and transportation, environment protection, oil and gas transportation, flood and drought control, detection of forest fire and earthquake monitoring.
