Subject field(s)
  • Spacecraft
CONT

GOES-9, a three axis stabilized spacecraft, remains stationary in space which allows the [imager and sounder] instruments to be continuously pointed at the earth. The scanning system moves back and forth(i. e., east to west and then west to east) as it moves north to south. While the spacecraft is stationary, it is not absolutely still. Earth location and registration accuracy are [affected] by orbital motions, instrument motion, and thermal distortion. A complicated set of navigation(earth location) and registration(image-to-image location of a landmark) correction schemes are necessary to compensate for these effects.... The registration schemes briefly are : 1) image motion compensation(IMC) and 2) mirror motion compensation(MMC). The IMC removes spacecraft orbit and attitude motion from each image. The MMC automatically corrects for the predictable effects of the instrument mirror motions.

Subject field(s)
  • Physical Geography (General)
DEF

In a panoramic camera system, the displacement of images of ground points from their expected cylindrical position caused by the translation of the lens or negative surface (a motion used to compensate for image motion during exposure time).

Record 3 2004-01-07

English

Subject field(s)
  • Physical Geography (General)
DEF

In a panoramic camera system, the displacement of images of ground points from their expected vertical panoramic positions caused by the tipping of the scan axis within the vertical plane of the flight path. This distortion is additive and modifies again the image positions of points already influenced by panoramic distortion, scan positional distortion, and image motion compensation distortion.
