Kevin Schuchmann Email Address: The program can be made to process these WAV files into images in a variety of projections, and can create colour composites of numerous types. The dynamic range looks quite good though, as you can see from the telemetry bars. Mercator , text overlays, automated web page creation , temperature display, GPS interfacing, wide-area composite image creation and computer control for many weather satellite receivers, communications receivers, and scanners. One of the best such programs is IrvanView , created by Irfan Skiljan. IrfanView is completely free, and is one of the most popular pieces of software of its type.

A number of dedicated amateur programmers have produced software packages that can be obtained either free, or for a very modest charge, and produce very high-quality images indeed. View all posts by Alexandru Csete. A demo version is available, but JVcomm32 must be registered to create usable images.

The only other item you’ll need is an antenna for receiving the circularly polarised signals. I have tried to contact him via Facebook. IrfanView is completely free, and is one of the most popular pieces of software of its type. Wxsat can decode images in real-time. Satscape aptdecode primarily a fantastic satellite tracking program with aptdecocer beautifully crafter interface. The pixel intensity from the instruments AM modulates a 2.

The APT format is very simple and straightforward. APT Weather Satellite Reception – Decoding and Display Software Overview Although expensive dedicated interfaces with accompanying software are available from commercial suppliers of weather satellite hardware, most enthusiasts these days decode the APT data from the NOAA satellites using their personal computer and its associated soundcard.

Finally, the output stream is re-sampled to samples per second which is the qptdecoder rate of the APT data. As you can see aptdecodet practical decoder will need some more tuning to produce a perfect image. It can view all the common and many uncommon image formats and has an impressive ‘slideshow’ feature.

The resulting image is shown below. To release its full power, registration is required, although the freeware version has more than sufficient features for the beginner. The simple decoder runs at a fixed clock; however, the clock in the signal runs too fast while the satellite is approaching, and too slow while the satellite is receding. The link to Patrik’s site no longer works.

The same data decoded and contrast enhanced using wxtoimg on Linux is available here. A simple way to measure the amplitude of the 2. Therefore, the receiver consists of an FM receiver followed by an amplitude detector that translates the amplitude aptrecoder the 2.

The basic version of Satsignal is free to use, but registration is required to unlock its full range of image processing tools. The program can simultaneously save the image as a bitmap and store the raw data as a WAV file for future aptdeoder and manipulation as the signal is being received.

If we convert the audio to kHz, the 2. The data is converted to unsigned char corresponding to the 8 bit resolution of APT.

The curvature in the image is timing skew caused by Doppler shift. Satscape can combine its tracking powers to automatically ‘switch on’ WAV file recording when a satellite comes within range.

SatScape Scott Hather Satscape is primarily a fantastic satellite tracking program with a beautifully crafter interface. Satsignal differs from the above programs in that it does not actually demodulate NOAA data transmissions.

This is the most complex of the programs listed. This site is not affiliated with the aptdecoddr WXtoImg Project, and is merely an attempt to provide a place for people to download the software as it seems the original developer has abandoned the project.
