WXtoImg Description

WXtoImg - An application able to decode APT and WEFAX signals from weather satellites. WXtoImg is a free software that will help you decode WEFAX and APT signals from weather satellites.WXtoImg is fully automated weather satellite recording, decoding, editing, and viewing software. WXtoImg supports map overlays, advanced colour enhancements, 3-D images, animations, multi-pass images, projection transformation (e.g. Mercator), text overlays, automated web page creation, temperature display, and control for many weather satellite receivers, communications receivers, and scanners.WXtoImg supports both APT transmissions from polar orbiting satellites and WEFAX transmissions from geostationary satellites. WXtoImg has a built in set of image processing facilities, but can output raw images for further processing. Output is in JPEG, PNG, BMP, PBM (PGM/PPM/PNM), or AVI format.WXtoImg attempts to produce reasonable images from receivers which have too narrow an IF bandwidth (e.g. scanners) although there are limitations on what can be done. WXtoImg uses the telemetry data on NOAA APT images to very accurately calibrate the image, correct for non-linearities in signal strength, and make adjustments for gain changes across the pass. The telemetry data is also used to calibrate the instruments to provide for very accurate temperature readings.On GOES satellites, the grayscale is used to correct for non-linearities in signal strength and normalise the image. Accurate temperature calibration on IR images is also performed. On other satellites, the grayscale and black and white bars are used to adjust the gain.WXtoImg uses a PLL technique to correct for doppler shift and ensure straight images on NOAA satellites even in the presence of very high noise levels or poor signal quality. In order to correct the doppler shift and to help ensure the images are straight, WXtoImg uses a burst cycle PLL on Resurs and Meteor satellites.Requirements:· Macintosh G3, G4, G5 and Intel processorsLimitations:· 10 seconds delay screen.
