Satellite SPOT
.A resources satellite earth first one of Europe. Developed based on international cooperation of National Space Institute (France Centre NATIONAL D 'E' TUDES SPTIALS - CNES) with Belgium and Sweden. Satellite SPOT.The 2 HRV camera up in orbit height is different. A satellite designed to have the ability to provide detailed ground better words, the difference in space on the system, multiple cameras during the wave 20 meters.10 meters include photographic equipment side. Therefore, can shoot the same repeated for several days, can be used to make three-dimensional image (Stereo image). Besides, it also can be compared to the map scale, 1: 50000 automatically
during the year 2529 until nowadays there are four SPOT band satellite sent into orbit respectively as follows:
SPOT - 1 sent into orbit on 22 February. Year 2529 weighs approximately 1 750 kg, with 2x2x3.5 meter, collector of energy from the sun 15.6 meters long Orbit in attributes, the sun angle 97 degrees in altitude 830 kilometers. Passes through the equator at about 10.30.And orbit back to recording the original all 26 day by orbit around the world 369 around SPOT - 1 contains of satellite camera system and remote transmission system Camera system consists of a number HRV 2. System, multiple cameras the wave.Can be used to record the 2 system simultaneously
.SPOT - 2 sent into orbit on 22 January 2533 have similar properties to SPOT - 1 the SPOT - 3 have obstacles can not work. Since the year 2529 onwards, until the end of the year2539 image data received from the satellite SPOT three this star has more than 5 million images that covers an area of 60 x 60 km 2. At the time, provide information 12 years
.SPOT - 4 has developed up to the present. And is designed to more efficient than previous models. SPOT satellite is
- the new wave short wave infrared (Short wave infrared). Can be divided into
.Plants out of the soil better
-. To increase the ability to record
.- adding device for recording information plants in a wide angle (Wide angle vegetation instrument) can check the cover and plant varieties of the world in a short amount of time. Is the day!Improved data recording position. The function of satellite data recorder system DORIS
.Environmental scientists pay attention to system SPOT because adding a mirror on the equipment to HRV is a recording device, point angle 27 degrees. With the survey, causing an advantage up 3 reasons as follows:
