Explanations: 

1) Calibration Method: 


The geometric calibration is based on a set of 84 images of a defined geometry target 

with 240 GCPs. 

Number of point measurements for the panchromatic camera : 19388 

Number of point measurements for the multispectral camera : 64864 

Determination of the image parameters by Least Squares Adjustment. 

Software used for the adjustment: BINGO (GIP Eng. Aalen, Germany) 

2) Level 2 Image Coordinate System: PAN 14430 pixel by 9420 pixel 

MS 4810 pixel by 3140 pixel 

The image coordinate system of the Level 2 images is shown in the above figure. The 

level 2 image consists of 11500 columns and 7500 rows, which leads to a total image 

format of 103.5 * 67.5 mm. The coordinate of the principal point in the level 2 image is 

given on page 3 of this report. The above figure shows the position of an example 

principal point at the coordinate (-0.123 / 0.345). 

( 21 of 52 ) 



3) Level 3 Image Coordinate System: PAN 14430 pixel by 9420 pixel 

(after rotation of 270° CW) MS 4810 pixel by 3140 pixel 

Panchromatic Image Format Multispectral Image Format 

================================================================ 

4) Position of Principal Point in Level 3 Image 

The position of the principal point in the level 3 image depends on the “rotation” setting 

used in the OPC during the pan-sharpening step. The exact position relative to the 

image center is given in the table below as a function of the rotation setting used in the 

OPC. The coordinates are specified for clockwise (CW) rotation in steps of 90 

degrees, according to the principal point coordinate given on page 3 for high- and low 

resolution images. 

Image Format Clockwise Rotation PPA 

(Degree) X Y 

Level 2 - 0.000 0.144 

Level 3 0 0.000 0.144 

Level 3 90 0.144 0.000 

Level 3 180 0.000 -0.144 

Level 3 270 -0.144 0.000 

( 22 of 52 ) 



The coordinates in the figure below are only example values to illustrate the effect of 

image rotation on the principal point position, and do not correspond to the camera 

described in this report.

Lens Resolving Power 

The following curves show the development of the modulation transfer 

function across different image heights of the panchromatic cones. 

The curves are given for the meridonial (tangential) and sagital (radial) 

component of signals at frequencies of 10, 20, 40 and 80 line pairs per 

millimeter. 

As the MTF is a function of the specific aperture size used, one set of 

curves is given for each aperture size.

Notes 


COLUMN anomaly: all pixels below the Qmax detector at location (X,Y) may be 

affected. 

PIXEL anomaly: single detector at location (X,Y) is not functioning within normal range 

The Level0 coordinates exclude the two leftmost pixels containing the line index: the 

corresponding pixel can therefore be located at column (X+2,Y).

Explanations: 

Calibration Method: 


The radiometric calibration is based on a series of 60 flat field images for each 

aperture size and sensor. The flat field is illuminated by eight normal light lamps with 

known spectral illumination curves. 

These images are used to calculate the specific sensitivity of each pixel to compensate 

local as well as global variations in sensitivity. Sensitivity tables are calculated for each 

sensor and aperture setting, and applied during post processing from level 0 to level 1. 

Outlier Pixels that do not have a linear behavior as described in the CCD specifications 

are marked as defective during the calibration procedure. These pixels are not used or 

only partially used during post processing and the information is restored by 

interpolation between the neighborhood pixels surrounding the defective pixels. 

Certain pixels that are named Qmax pixels due to the fact that they can only store and 

transfer charge up to a certain maximum amount are detected in an additional 

calibration step. These pixels are treated differently during post processing, since their 

behavior can affect not only single pixel values but whole columns.

Calibration of Shutter Release Times: 


The shutter release times measured during the calibration describe the 

time from the moment when the electrical current through the shutter is 

turned off by the electronics, until the shutter is mechanically closed. 

This time is relevant for the exposure control and needs to be known 

before image recording can take place.

Calibration of Negative Substrate Voltage (VNS): 

For optimum performance of the DALSA CCD sensors, the negative 

substrate voltage is adjusted to a value specified by DALSA. 

This voltage value is measured to achieve the best anti-blooming 

performance possible for each particular sensor.

Calibration of Intensity Threshold for Exposure Control: 

Each CCD sensor and electronics module varies slightly in global 

sensitivity and intensity scale. 

Therefore the maximum possible intensity of each sensor needs to be 

measured to evaluate the sensitivity behaviour of the CCD and 

electronics. 

This value is used as a threshold for the exposure control dialogue shown 

in the in-flight user interface of the UCD.
