# @nyx/orbit-determination

Initial Orbit Determination (IOD) tool for deriving orbital elements from
observations

TypeScript package. Built with tsc/tsup; consumed by other workspaces.

## Scripts

| Command           | Definition  |
| ----------------- | ----------- |
| `pnpm build`      | tsc         |
| `pnpm test`       | vitest run  |
| `pnpm test:watch` | vitest      |
| `pnpm lint`       | eslint src/ |

## Layout

- `src/`

## Working on this package

The fastest local loop is via Nx:

```bash
pnpm nx test nyx-orbit-determination
pnpm nx lint nyx-orbit-determination
pnpm nx build nyx-orbit-determination
```

When Nx is unhappy (usually because another worktree has duplicate project
names), bypass it with the underlying tools from this directory:

```bash
npx tsc --noEmit
npx vitest run
```
