Satellite Tools

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.

Below are some calculators. JavaScript is required and is used for calculations only.

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

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
