Then I developed the photograph and at that moment I was able to see if this construction was working! And yes, it worked, see the pictures below. 67 Page Chapter 08 Construction of Satellite Ground Station Contents Introduction Software Features Versions Latest Version Calibration Sample Images 68 Page Construction of Satellite Ground Station Introduction to WXtoImg Software T he WXtoImg software is developed by Craig Anderson, from Auckland, New Zealand of Abstract Technologies. Then I played back the recorded signal of the weather satellite and waited till the end of the picture. The telemetry data is also used to calibrate the instruments to provide for very accurate temperature readings. I used a camera lens to project the pixel on photographic paper and put that in front of the modified television (in a complete dark room of course). WXtoImg uses the telemetry data on NOAA APT images to very accurately calibrate the image, correct for non-linearities in signal strength, and makeadjustments for gain changes across the pass. I built a new transistor based deflection amplifier with a vertical saw tooth signal of 200 seconds and a horizontal saw tooth synchronized on the 4 Hz pulses from the decoder unit. After that I modified an old b/w television for what I only needed: the High voltage part, the deflection unit and the amplifier for the Z-signal. The data voice in Figure 9 can be converted into image, that produces cloud images with the help of WXtoImg software 11 12to produces.

Easy spoken, but not easy done!įirst I built a decoder to get the 4 Hz sync signals and the filtered AM signal with the pixel information. CALIBRATION APPROACHES FOR S-NPP CRIS FULL SPECTRAL.

Since I did not had a facsimile the only way was to build something to display the lines on and take a photograph of it. My first 2400Hz Weather Satellite decoder
