SPOT satelliteA survey of global resources satellites, the first moon of Europe developed based on international cooperation of the national space Institute, France (Centre NATIONAL D ' E'TUDES SPTIALS-CNES) with Belgium and Sweden. Satellite SPOT HRV data recording device contains two or more cameras in orbit at a different height. The satellite is designed to be able to provide better ground-details. That is, different areas in several waves, 20-meter range camera system and in the system of a single wave range.10 metre Side imaging devices, can duplicate the original photo phapboriwen multiple days can be made 3D (Stereo image). in addition, it can also be compared to a map scale 1:50000.During this current 2529 (1986) until There are four SPOT satellites sent into orbit, respectively. Is as follows:SPOT-1 sent into orbit on February 22, there are approximately 1750 kg weight, 2529 (1986) size 2x2xNN3D5 m, with a panel powered 15.6 meters long, orbit the Sun in relationship to extinguish the Sun. 97-degree tilt angle in elevation 830 km, orbiting over the Equator around 10.30 am and the original every khotroklap comes to save the day by phapboriwen 26 khotronop Earth band around the SPOT-369 1 satellite. Camera system and a remote signal system. The system consists of a camera, a camera system HRV 2 is multiple wave range and the range of a single wave can use either system 2.SPOT-2 sent into orbit when the properties are similar to the January 22 2533 (1990) SPOT-the SPOT-3 section 1 seems unable to perform since 2529 (1986). until the end of the image data obtained from 2539 (1996) satellite samduang on this SPOT, both with more than 5 million images covering an area of 60 x 60 km 2. At the time of service 12 years.SPOT-4 has been developed to use and are designed to performance than earlier versions of the SPOT satellites are.-Add Infrared waves (Short wave infrared) short wave comes, you can differentiate.Plants out of the ground.-To increase the ability to save data.-Add a device for recording information on plants in the field of view (Wide angle vegetation instrument) can be traced to the world's rainforest, covering, and in a short period of time is, on a daily basis.-Improvements to data log location The data recorder's satellite system, DORISEnvironmental scientist, interested in adding a mirror to SPOT, because the system on HRV is the recording device. Point angle + 27° with space exploration , To have three reasons:
