Pakistan emergency: half a month in bursts of two Chinese military reconnaissance sat

Britain, “Jane’s Defense Weekly” (published in advance) a:

15, China successfully launched the “V remote sensing satellite,” This shows that 1 in the launch of the “Four remote sensing”, the country is at full speed to expand its reconnaissance satellite system.

“Remote Sensing” is the name was later changed. “One of remote sensing satellite” is the “vanguard V” synthetic aperture radar satellites, by the Shanghai Aerospace Technology Research Institute to create. “Remote Sensing II” is the “vanguard VI” digital imaging spy satellite by the Chinese Academy of Space Technology to create.

“Vanguard” series dating back to 1975. Before 2006, China had launched 25 “pioneer” of spy satellites, is divided into four generations, including the “One pioneer” and “vanguard 1A”, “vanguard 1B” “Vanguard II”, “vanguard Three” and "vanguard Four. "

“V vanguard” China is the first real-time synthetic aperture radar satellite. “VI vanguard” of China’s use of off-axis three-optical systems and high-speed real-time image compression coding technology. This coding technology will be used for future lunar observation and “one environment,” Constellation, and so on.

“One environment”, “vanguard” of the satellite systems, from small-scale imaging of two spy satellites and a synthetic aperture radar satellites. The main satellite will be launched in the second half of this year. China plans through international cooperation it has developed into eight-shaped constellation. In the end, “Environment” Constellation could help partner countries to monitor the waters outside the naval forces. Potential customers could include Brazil, Egypt, Iran and Pakistan.

Taking into account China successfully launched a communications satellite to Nigeria, China will clearly have the ability to more developing countries into the club of military satellites.

General Staff Headquarters is the real user

Satellite pioneer family decision-making and the right to use the Same People’s Liberation Army General Staff, its army as a model of strategic weapons system structure and function of the key, with the goal of fighting the discovery, identification, location, as well as to combat the damage assessment of the effect of other important The task, according to the needs of users and R & D projects, with the technological progress and improve.

Satellite Laodangyizhuang

Return to film-imaging satellite for remote sensing space cause in the first set a precedent, more than three decades the development of five models, the technology is mature, impressive results.

One pioneer (FSW-0): return to the first generation of camera-1974-1987 census satellite launch 10 years, 9 the successful launch and recovery second, 3-5 days in orbit, time, film-resolution 10-meter ground for the ground Fixed target discovery and identification.

A vanguard One (FSW-1): return to the first generation of photo-mapping satellite, fixed for targeting and mapping. 1987-1993 launch 5-year period, 4 successful recovery. 8 days in orbit time. Bai Yumi precision targeting. The two models of the former stars of the targeting information was made China’s first generation of strategic weapons (DF-3A, 4A, 5A) to form a real combat system.

One pioneer B (FSW-2): the return of the second generation of satellite-photo survey, 1992-1996 launch 3rd, were successfully recovered. Time to 15 days in orbit, a ground resolution of 2.5 meters film than the first generation raised three times the resolution. The model has the task of the vanguard Three-satellite transmission to succeed.

Vanguard II (FSW-4): the return of first-generation camera-2004-2005 detailed investigation of the satellite launch 2 years, were successfully recovered. Time to 27 days in orbit, a ground resolution of 0.5 meters film, the realization of the Yami-class imaging technology leap. The satellite model has the task of the vanguard on the 6th to take over the satellite transmission.

Four scouts (FSW-3): the return of the second generation of photo-mapping satellite 2003-2005 launch of 3 years, were successfully recovered. Time in orbit for 18 days, fixed on the ground targeting accuracy of 10 meters to meet the second generation of strategic missiles targeting accuracy of the demand, the model of the successful launch and recovery, marking China’s second-generation strategic weapons (DF-5B, DF -31A, DH-10) form a system in actual combat ability.

Satellite transmission in the ascendant

In recent years, high-tech defense as a priority to the development of the object, pioneer family has added a lot of new faces.

Photo-imaging remote sensing satellite data transmission, can significantly improve the real-time intelligence, to extend the working life of the satellite, with the CCD camera technology, and its resolution on the ground close to the level of recovery-type film, go a long way to replace the satellite’s power .

Three scouts (ZY-2): optical imaging satellite data transmission type 2000-2001 census-2004 launch of 3 years, all successful, two-year life span, the first satellite ground resolution of 3 meters, 1.5 meters to reach the follow-up stars to take over One pioneer return to the B-satellite survey.

VI pioneer (YG-2): optical imaging detailed investigation of satellite-based data transfer, in May 2007 to launch a ground resolution of one meter, the computer processed to enhance image resolution of 0.6 meters on the ground to take over the return of vanguard II Satellite-detailed investigation.

Radar imaging satellites, the use of synthetic aperture radar technology, and all-weather day when real-time reconnaissance, and to be able to detect a target for shallow groundwater, and optical imaging satellite, the superiority is obvious.

Vanguard V (YG-1): synthetic aperture radar reconnaissance satellite, launched in April 2006, a ground resolution of 5 meters.

Vanguard on the 7th (YG-3): synthetic aperture radar reconnaissance satellite, launched in November 2007, a resolution on the ground than on the 5th vanguard of a new raise.

Chain-day satellite glorious mission

Tracking and Data Relay Satellite, the transfer of low-earth orbit satellites to track the signal monitoring and control, and access to satellite image data transmission to relay information, is a global strategy for reconnaissance and surveillance to provide early warning of the important real-time messaging Means, but also the establishment of an integrated space-based global information network when an important and indispensable component.

China will one day chain under the banner of “services for the manned space flight,” the banner launched since the vanguard of new series of follow-up to the powerful satellite surveillance capability can be fully tapped, the second generation in the Beidou navigation system under the guidance of my new type of missile weapon systems to achieve Great depth and strategic objectives of the real-time long-range precision strikes.
