According to the U.S. "National Defense Blog" on March 5, South Korean insiders said that South Korea's first "military spy satellite" launched at the end of last year had begun preliminary testing, and during the test period, a number of high-precision satellite images taken by the satellite were successfully transmitted. 
South Korean satellite launch) It is reported that the ** transmitted by this round of satellites was captured by the South Korea's self-developed photoelectric infrared (EO IR) sensor system on the satellite. The main firing range included Pyongyang, the capital of North Korea, the area around Pyongyang, and important ports of North Korea. The South Korean side said that South Korea has evaluated the satellite transmission. **The resolution is as expected. The important details in the diagram are very clear and of great value. However, due to secrecy reasons, South Korea did not disclose specific satellite images and did not announce the specific targets of the shooting. There is also news that testing is continuing, and starting next month, satellites will begin to produce "high-definition" images with higher resolution and more detail, which will also be a new challenge for satellite redundancy. Bandwidth of South Korea's ground-to-air wireless transmission system. 
Pyongyang) under the lens of Western satellites) also reported that the satellite will be officially used in June-July this year, entering the stage of full-scale reconnaissance mission. This will certainly improve South Korea's ability to independently monitor North Korea and reduce its reliance on U.S. intelligence** and satellite data support. But this is not the "end" of South Korea's satellite research and development and construction - it is reported that South Korea also plans to launch four synthetic aperture radar satellites into low-earth orbit in the near future to increase South Korea's "space military capability". In the future, South Korea wants to create an "independent satellite surveillance network" that can update North Korea every two hours. 
South Korean spy satellites awaiting launch) also signals that the "satellite race" between the two old enemies of South Korea and North Korea is intensifying. North Korea has reportedly said on several occasions that its two previous spy satellites are "going well." The DPRK has also repeatedly stated that the DPRK satellite has photographed the "key facilities" of the United States, South Korea, Italy and other countries in orbit, and has named the DPRK satellite to photograph several military facilities in the White House, the Pentagon, Seoul and the United States in **. Waiting for military ports in many places, it even said that "four aircraft carriers can be seen in the satellite". 
The White House** captured by North Korean satellites is very clear) However, the space monitoring agency said that North Korea had previously launched a spy satellite, and only one is still active. Marco, a satellite expert at Delft University of Technology in the Netherlands, said he had discovered the satellite's "orbit change maneuver," which means the North Korean satellite has propulsion capabilities and can be used in orbit for longer periods of time. 
North Korea launches spy satellite) At present, the military spy satellites launched by the two countries on the peninsula are high-resolution photographic satellites, mainly performing image intelligence gathering (IMINT) work. Through professional image analysis, satellites can help the two countries quickly adjust short- and medium-term decision-making in response to changes in each other's military deployments in a short period of time. It is of good tactical sense for the crisis situation on the peninsula. Therefore, both countries are vigorously developing such satellites. On the other hand, satellites can also collect intelligence data that can help guide strategic attack methods. And South Korea and North Korea, as well as the United States and North Korea, have the ability to carry out strategic attacks on each other. Therefore, the launch of this spy satellite has strengthened the strategic deterrence of the DPRK against the United States and South Korea and the ROK against the DPRK, and has also weakened the "satellite intelligence superiority" of the United States in the situation on the peninsula. 
North Korea's ballistic missiles could theoretically hit the continental United States) In the future, it is foreseeable that the two countries on the peninsula will launch satellites one after another to counter the North Korean background. "Cold confrontation" has continuously strengthened strategic intelligence superiority. It is reported that South Korea will launch a new satellite in a few months, while North Korea may launch a new spy satellite in March. As for the United States, although there is not enough evidence yet, there is speculation that the United States is planning to restart the long-stalled "anti-satellite** test" in order to increase its "space" space. United States. military superiority ".
