Ocean Monitoring Satellite

Japanese: 海洋監視衛星 - かいようかんしえいせい
Ocean Monitoring Satellite

...However, high-performance resource exploration satellites, etc., are considered to be sufficiently usable for limited reconnaissance purposes.
[Surveillance and surveillance satellite]
They are broadly divided into early warning satellites that detect ballistic missile launches early and issue warnings, nuclear explosion detection satellites that detect the radiation and flashes produced by nuclear explosions and monitor nuclear tests (except underground nuclear tests), and ocean monitoring satellites that monitor the movements of ships and submarines on the vast ocean. During the Gulf War, the United States used third-generation early warning satellites DSP-14 and 15 to detect Iraqi Scud missile launches, and analyzed the data within the U.S. mainland via data relay satellites, pinpointing the launch site to within 6 km accuracy, calculating the trajectory to calculate the predicted impact point and time, and transmitting the firing data to local Patriot interceptor missile units.

From [Cosmos Satellite]

...Cosmos 44 was launched for the Meteor series of weather satellites, Cosmos 41 for the Molniya series of communications satellites, and Cosmos 133 for the Soyuz series of manned spacecraft. As military satellites, Cosmos has been launched for navigation, early warning, ocean surveillance, reconnaissance, and even for satellite attack testing, with the most notable being the ocean surveillance satellites and the satellite attack test satellites (killer satellites). The ocean surveillance satellites are used to monitor the movements of the U.S. Navy, and some of these satellites are equipped with nuclear reactors to provide high power to their radars. ...

…なお,高性能の資源探査衛星等は,限定的な偵察目的には十分使用可能と考えられる。
[警戒監視衛星]
 弾道ミサイル発射を早期に発見して警報を発する早期警戒衛星,核爆発で生じる放射線・閃光を探知して地下核実験を除く核実験を監視する核爆発探知衛星,広大な海洋上の艦船および潜水艦の動向を監視する海洋監視衛星に大別される。アメリカは湾岸戦争で第3世代の早期警戒衛星DSP‐14および15を用いてイラクのスカッド・ミサイルの発射を探知し,データ中継衛星を経由して米本土内で解析,発射地点を6km以内の精度で標定,軌道を計算して予想弾着地点と時刻を計算,射撃データを現地のペトリオット要撃ミサイル部隊に伝送している。…

【コスモス衛星】より

…気象衛星メテオールシリーズのためにはコスモス44号,通信衛星モルニヤシリーズのためにはコスモス41号が,そして有人宇宙船ソユーズシリーズのためにはコスモス133号がそれぞれに先駆けて打ち上げられている。軍事衛星としてのコスモスは,航行,早期警戒,海洋監視,偵察のほか衛星攻撃実験を目的としても打ち上げられているが,この中で注目されるのは海洋監視衛星と衛星攻撃実験衛星(キラー衛星)である。海洋監視衛星はアメリカ海軍の動きを監視するためのもので,この衛星にはレーダーに大電力を供給するために原子炉を積載しているものもある。…
