Satellite tools package
This package contains a few Python and Bash scripts to help you manage and process satellite data from SatDump.
The package contains the following scripts:
colorize_proba: applies a color filter and stretches contrast so that images from PROBA-2 or XEUVI appear realistic.xeuvize: leveragescolorize_probato first apply a color filter, then assembles the images in a GIF.discordize: reduces the resolution of an image to less than 8000 px wide, suitable for upload on Discord, Reddit or Twitter that cannot really handle larger images.heatmap: applies a CLUT (Color Look-up Table) from OpenCV to a specified image. The list of CLUTs is available hererectify: applies geometric correction to an image to compensate for Earth's curve. Useful e.g. for new Meteor commissionings where this is not supported in SatDump yet, or for other instruments.
Calculators
Below are some calculators. JavaScript is required and is used for calculations only.
Sample rate calculator
Allows you to calculate what sample rate to use according to a given symbol rate.
Oversampling calculator
To calculate the oversampling rates, input the satellite's symbol rate expressed in Msym/s.
| Minimum oversampling | Good oversampling | Ideal oversampling |
|---|---|---|
| Invalid input | Invalid input | Invalid input |
Storage calculator
Allows you to calculate the storage space necessary for satellite recordings
Storage calculator
To calculate the necessary storage, please input the SDR sample rate and select the bit depth.
| Write rate | Space for 1 minute | Space for a pass (15 min) |
|---|---|---|
| Invalid input | Invalid input | Invalid input |
Metop IASI calculator
Allows you to find the IASI channel in SatDump based on an input wavelength.
IASI channel calculator
To calculate the channel, input a wavelength expressed in nanometers (nm)
| Wavenumber | IASI channel |

Aqua AIRS calculator
Allows you to find the AIRS channel in SatDump based on an input wavelength.
AIRS Channel calculator
To calculate the channel, input a wavelength expressed in nanometers (nm)
