Azimuth Determining System (ADS) 16 February 2016 ATP 3-09.02 D-5 D-20. Step 3—Chip on a coordinate: Select Start, Programs, FOS. The FOS Desktop is displayed. Display a CFF – Grid message. The CFF - Grid message format is displayed. Note. When DPSS-Suite software is loaded onto a FOS system, and a CFF - Grid message format is displayed, ‘(<R>=REFINE TGT POSITION)’ is displayed at the bottom left of the screen. Also, the ‘TLE’ (Target Location Error) field is displayed. ENTER ‘B’ in the DEST field to address this message to your member. Then enter your current grid coordinates: EASTING: 12345. NORTHING: 67890. Press the ‘Refine’ key to begin the process of more precisely refining this location/target. The PSS-SOF toolbar and the ‘Extract DPPDB stereo image pair’ window are displayed. Select the Extract button on the ‘Extract DPPDB stereo image pair’ window. The ‘PSS-SOF DPPDB Exploitation Tool’ window is displayed. Note. Selecting ‘Extract’ causes the program to search for the appropriate DPPDB Chip and Stereo Image for the left and right view. It also generates the ‘PSS-SOF DPPDB Exploitation Tool’ window that tells you how many meters and degrees the target marker on the stereo image is from the coordinates you entered in the CFF - Grid message. If the appropriate DPPDB image segment has not been loaded on your computer, you will receive a warning message that says ‘Failed to Find a DPPDB image segment that contains the specified target coordinates. OK the window. The Left Chip View and Right Chip View are displayed: The Left Chip View and Right Chip View are stereo views of DPPDB chips. Each satellite image may have been taken at different times and at a slightly different angle. The initial target location that you are refining is marked with a red target marker near the center of the image. The Left Chip View image bar is yellow because it is the active chip. To activate the Right Chip View click on it one time. Notice the Graphic/Scale in yellow at the bottom left of each image. The vertical yellow line and horizontal yellow line represent the length of 50 meters on this image based on the pixel ratio of 1:1. Once you change the ratios to 1:2 or 1:4, the distance each yellow line represents also changes to the corresponding computed distances. North is up because of the changes we made to the default settings. Click on the Right Chip View. The Right Chip View is activated. Select the drop-down arrow that is to the left of the yellow bar. This arrow opens the Brightness and Contrast options. Note. To more precisely define a location it may be very important to set the contrast and brightness so you can see more details about the area. The brightness and contrast can be adjusted by using the sliders. Or you can enter numbers into the boxes. The sliders can also be adjusted by selecting one of the sliders and then using page up or page down. This moves the sliders in increments of 10. When you select the slider, and then use the arrow keys, it moves the sliders in increments of one. No other action can be performed on the imagery until this dialog box is closed using the Close button. There are two additional buttons, SAVE MPG and OUTPUT. These buttons are used if you are equipped with the proper external equipment to copy the target image to an external source.
