Satellite LANDSAT
characteristics of satellite LANDSAT 1 - and 2 3 is small. Shaped like a butterfly, was about 953 kilograms, approximately 3 meters wide and about 1.5 meter, collector of energy from the sun like the two wings has a width of about 4 meters (picture 3.1) orbit high level 900 kilometers. And the speed 6.5 kilometers per second. For LANDSAT 4 - 5 (picture 3.2) is designed to be more complex than LANDSAT 1 - 2 3 shape and are modified to improve the ability to control the orbits of satellites. An increase in a superior capability and LANDSAT 1 - 2 3 is the use of communication systems Tracking and.Relay Satellite (TDRS) can pay with data from the satellite to the world at the time, similar to the recording time (Real Time) reduce the tape recorder with the limitation of age. In use, the height of the orbital reduced to 705 kilometers.Faster than is 16 days LANDSAT working experience is currently LANDSAT and 4-5 LANDSAT - 7
.The orbit of the satellite LANDSAT circle between 9 degrees north - South is associated with the sun (Sun synchronous) means. Characteristics of orbiting satellites in accordance with the trajectory of the earth around the sun.The local time the same. The orbit in this manner the advantages are pictures taken in the same latitude will be under the illumination from the sun at nearby. And can be compared to see various styles.
