The Cosmos-2428 resolution in response to the U.S.
Spy satellites must collect intelligence without being drawn by the Earth’s intense gravity. To do this, they must orbit the Earth at a very high speed. It is reported that they maintain a speed of about 5 miles per second when they are 311 miles above the ground, making spy satellites orbit the Earth about 14.5 times a day. Low-orbit spy satellites’ surveillance systems can be considered the cornerstone of space warfare.
The only superpower that can compete with the United States is Russia. Russia is also spying on every corner of the world through many spy satellites. Cosmos-2428 is a high-performance reconnaissance spy satellite with a high resolution comparable to the U.S. Keyhole. It is known to have a maximum resolution of about 8 inches, and it closely monitors the movements of countries worldwide, including the United States. They also operate an early warning satellite system combining Oko and Proton satellites, which can monitor missile attacks and nuclear tests.
France and Germany have reconnaissance satellites named Helios-2A and SAR-Lupe, respectively. Israel uses Ofek to target its enemies, while Switzerland operates an electronic information collection satellite. Japan recently launched an observation satellite called Gokaku, which is being utilized to surveil the Korean Peninsula, making it a reconnaissance satellite. Currently, seven secret reconnaissance satellites collect information on the Korean Peninsula. Japan’s optical reconnaissance satellites can detect objects as small as 12 inches.
South Korea operates Arirang 3, a multi-purpose practical satellite rather than a spy satellite. It is reasonably high-level and has a resolution of 28 inches. They are also developing five 12-inch military reconnaissance satellites to monitor North Korea, a project known as 425. The first military reconnaissance satellite was launched on December 2 of last year, and the second was launched on April 8.
Our military’s second military reconnaissance satellite was launched on the 8th at 8:17 a.m. Korean time (7:17 p.m. local time) from the Kennedy Space Center on Merritt Island, Florida, USA, aboard the SpaceX’s Falcon 9 launcher. About 45 minutes later, around 9:02 a.m., it successfully separated from the launcher and entered the target orbit. Later in the afternoon, it successfully transmitted and received data with the domestic ground station, marking the final success of the launch.
This launch took place about three months after the launch of the first reconnaissance satellite at the end of last year. The second reconnaissance satellite is a SAR satellite that generates images by sequentially firing radio waves towards the ground while orbiting an inclined orbit and receiving the reflected signals.
