sat-rs example
======

This crate contains an example application which simulates an on-board software.
It uses various components provided by the sat-rs framework to do this. As such, it shows how
a more complex real on-board software could be built from these components.
The application opens a UDP server on port 7301 to receive telecommands.

You can run the application using `cargo run`. The `simpleclient` binary target sends a
ping telecommand and then verifies the telemetry generated by the example application.
It can be run like this:

```rs
cargo run --bin simpleclient
```

This repository also contains a more complex client using the
[Python tmtccmd](https://github.com/robamu-org/tmtccmd) module.

# Using the tmtccmd Python client

The python client requires a valid installation of the
[tmtccmd package](https://github.com/robamu-org/tmtccmd).

It is recommended to use a virtual environment to do this. To set up one in the command line,
you can use `python3 -m venv venv` on Unix systems or `py -m venv venv` on Windows systems.
After doing this, you can check the [venv tutorial](https://docs.python.org/3/tutorial/venv.html)
on how to activate the environment and then use the following command to install the required
dependency:

```sh
pip install -r requirements.txt
```

Alternatively, if you would like to use the GUI functionality provided by `tmtccmd`, you can also
install it manually with

```sh
pip install tmtccmd[gui]
```

After setting up the dependencies, you can simply run the `main.py` script to send commands
to the OBSW example and to view and handle incoming telemetry. The script and the `tmtccmd`
framework it uses allow to easily add and expose additional telecommand and telemetry handling
as Python code. For example, you can use the following command to send a ping like done with
the `simpleclient`:

```sh
./main.py -s test -o ping
```

You can also simply call the script without any arguments to view a list of services (`-s` flag)
and corresponding op codes (`-o` flag) for each service.
