Remote sensing satellites of USA France and japan
Answers
There are many kinds of Earth observation satellites. They are distinguished by their equipped sensors. For example, sensors with specifications of a swath width of 185km and a spatial resolution of 30m recognize objects more than 30mx30m in size in an 185km-wide area.
Some Earth observation satellites are listed below.
1. Japan’s Earth observation satellites
Momo-1 (Marine observing satellite, MOS-1/1b) : Optical sensor, passive micro wave sensor
Fuyo-1 (Japanese earth resources satellite, JERS-1) : Optical sensor, active micro wave sensor
Midori-1 (Advanced earth observing satellite, ADEOS) : Optical sensor, Passive micro wave sensor
Midori-2 (Advanced earth observing satellite, ADEOSII) : Optical sensor, passive micro wave sensor
Daichi (Advanced land observing satellite, ALOS) : Optical sensor, active micro wave sensor
2. International satellites equipped with Japanese sensors
Tropical Rainfall Measurement Mission, TRMM) : Active micro wave sensor
Aqua : Passive micro wave sensor
