···11+# Satellite observatory
22+33+Inspired by my previous project [iss_locator.rs](https://tangled.sh/@technoduck.me/iss_locator.rs), and the indomitable human spirit,
44+its an interactive program displaying the current location of the ISS.
55+66+The UI is made using [ratatui.rs](https://ratatui.rs/), which I hopefully will be able to then also port to [ratzilla](https://github.com/orhun/ratzilla).
77+88+99+## Usage
1010+1111+Can either be compiled normally, or with a `logging` feature, to enable tracing everything into log.log file (horrible alas it works).
1212+1313+## Methods
1414+1515+Location of the ISS is obtained from [celestrak](https://celestrak.org), where the Two Line Element for the ISS's orbit is obtained.
1616+1717+SGP4 algorithms + Earth Rotation angle are used to calculate the location and velocity at any specific point in time.
1818+1919+2020+## Future?
2121+2222+While the code for now is a bit ISS specific other satellites can be easily added, by fetching their TLE and doing the same calculations.
