SatSignal
What is SatSignal?
|
| Here is an example of the new Background
Overlay mode. By skilfully blending the temperature information
derived from the thermal channel with the recently released Blue
Marble Next Generation images of the earth, night-time images can be
presented looking as if they were daytime ones, with an attractive blue
sea background and naturally coloured land areas.
You have full control of what background images are used, so you are not restricted to the Blue Marble data. You also have full control over the blending process, so you can show colder clouds as light (as in the example here) or dark for a more dramatic presentation. Files to get you started are provided. |

Users have asked to support this software by registering, so I have now provided this facility. There are a number of extras for registered users including map overlays, input from bitmap (.BMP) image files, and the direct display of apparent temperature. These are available upon registration. I would also like those who use the program as a regular part of automated signal reception to consider registering, hence the toolbar and batch operation are included in the registered program. Click here for more information about registering SatSignal.
Please note that SatSignal 5 is a new product and requires a new licence code.
If you get error messages about missing DLLs when you try to run SatSignal, please consult the library notes page.

| V5.0.0 | Add background mode in EasyOverlay, [needs e.g. BlueMarble JPEG background 5400 x 2700 pixels, Plate Carree projection JPEG image accepted, size from 2700 x 1350 pixels to 8000 x 4000 pixels, download the 8km data, not the 2km data!, needs LUT 100 x 2 x 24-bit, e.g. LutLightClouds-B.bmp, 2nd palette line provides gain control - 255 = palette colour, set paths to files on Options, EasyOverlay, Background Mode, enable normal or background-mode EasyOverlay, provide simple LUT palette editor], make EasyOverlay filename check for satellite name case insensitive, honour individual overlays on channels A and B, accept test pattern from MTSAT as valid WEFAX header, add ErrorLevel = 1 return if bad WEFAX header found, improved WEFAX level determination, improved APT telemetry phasing check, if geostationary forced from command-line - ignore NOAA-only, make toolbar button reflect histogram equalisation state, extend Auto Update setting to "reload required" situations. |
| V5.0.2 | Add separate control of boundary overlay in Background Mode, remove un-needed reminder to save Background Mode LUT. |
| V5.0.4 | Add multi-language support, add support for Sky Eye images (1800 pixel wide DIBs), display registration dialog after 30-day trial has expired, improved robustness for MTSAT-1R decoding, don't let bad WEFAX file stop batch operation. |
| V5.0.6 | Improved Windows Vista compatibility. |
| V5.0.8 | Restore gridline display. |
| V5.1.0 | Allow choice of mouse scroll direction,

TonLindemann-CLUTs.zip (1.8MB) -
stepped and smooth CLUTs from Dutch weather expert Ton Lindemann. (The
file also includes land-sea LUTs for use with GeoSatSignal). They look
for cold cloud tops allowing easier recognition of possible rainfall and
severe weather. The readme is also updated with more information about
meteorological use of enhancement of IR-satellite imagery. You can
also refer to Ton's Web site

| V1.0.4 | Is a companion program for building your own colour look-up tables to use with SatSignal. |
| V1.0.6 | Adds a Save As option. Includes source code. |
The sample images give an idea of the program's capabilities, but the large images are only one quarter of full size and do not give a fair impression of the quality of the program's output. Typically, each full-size Meteor or Resurs picture would decode to either 1 MB JPEG or 3 MB BMP files. The two pictures of Iceland are full scale, and were taken within an hour of each other on 1999 April 1. The NOAA image showing better contrast on the mountains, either because of the lower sun angle of the earlier picture or the stronger gamma correction of SatSignal, but with the higher resolution is achieved by Meteor with SatSignal, the higher elevation of Meteor also producing a lower noise signal.
Program to drive the SatSignal and WXtrack programs for automated decoding of a folder full of mixed satellite wave files.
Requirements
The registered version of SatSignal is required to run this program. No new libraries are required. A Pentium 200MMX processor or better is recommended, with at least 32MB of memory.

The program reads pass details from both WXtrack and SatSignal and plots the signal quality as a function of the range and bearing from your location. By building up such data over a sequence of satellite passes, you can build up a picture of the antenna polar diagram, and detect any nulls in the polar diagram. It is also possible to compare antennas, and an example of such a comparison may be found here.
This is a free, unsupported utility. Please ask questions in the SatSignal self-help group.
Current release
| V1.2.0 | Provide "good signals only" scale range option, add smoothing option for Azimuth plot, add visual scale for polar plots. |
| V1.3.0 | Add save of estimated horizon data derived from least elevation seen in polar plot. |
