## 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`

: leverages`colorize_proba`

to 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 here`rectify`

: 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 |
---|---|

Invalid input | Invalid input |

### 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)*

Wavenumber | AIRS Module | Module span | AIRS channel |
---|---|---|---|
