ESA OPS-SAT Rust experiment
========

This is the primary repository for the ESA OPS-SAT experiment.
The primary repository to generate packages for ESOC can be found [here](https://egit.irs.uni-stuttgart.de/rust/ops-sat-experiment).
You can also find some more general documentation about OPS-SAT there.

## Pre-Requisites

- Containerization provider like [docker](https://www.docker.com/) or
  [podman](https://podman.io/) installed
- [`cross`](https://github.com/cross-rs/cross) package installed

## Build

You might need to set the [`CROSS_CONTAINER_ENGINE`](https://github.com/cross-rs/cross/wiki/FAQ#explicitly-choose-the-container-engine)
and [`CROSS_ROOTLESS_CONTAINER_ENGINE`](https://github.com/cross-rs/cross/blob/main/docs/environment_variables.md#configuring-cross-with-environment-variables)
variables manually before calling cross.

### Debug Build

```sh
cross build
```

### Release Build

```sh
cross build --release
```

## Commanding Infrastructure

Commanding of the `ops-sat-rs` application is possible by different means.

### Using the `pyclient` and `pyserver` applications

You can find both commanding application inside the `pytmtc` folder.
You can also find a `requirements.txt` file there to install all required Python dependencies.

If you want to command the satellite using the OPS-SAT infrastrucute, start the `pyserver.py`
as a background application first, for example by simply running `pyserver.py` inside a
new terminal window.

After that, you can run `pyclient.py -p /test/ping -l` to send a ping telecommand and then
go into listener mode using the following `tmtc_conf.json` file:

```json
{
    "com_if": "tcp",
    "tcpip_tcp_ip_addr": "127.0.0.1",
    "tcpip_tcp_port": 4097
}
```

You can run `pyclient.py -T` or `pyclient.py -h` for more information on the client application.
