## 🌟 Overview

The WIA-DEF-010 standard defines the technical framework for military satellite systems, including reconnaissance, communication, navigation, and early warning capabilities. It provides specifications for satellite operations, orbital mechanics, payload systems, ground control, and secure data links.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to provide a comprehensive framework for military satellite operations that enhance global security, situational awareness, and communication capabilities while promoting responsible space governance.

## 🎯 Key Features

- **Reconnaissance Systems**: IMINT, SIGINT, ELINT capabilities
- **Communication Networks**: MILSATCOM, secure tactical communications
- **Navigation Services**: GPS, GLONASS, Galileo, BeiDou integration
- **Early Warning**: SBIRS, DSP missile detection systems
- **Orbital Mechanics**: Trajectory planning and station-keeping
- **Ground Control**: Command & control infrastructure
- **Secure Data Links**: Encrypted downlink/uplink protocols

## 📊 Core Concepts

### 1. Satellite Types

```
Military Satellites:
├── Reconnaissance
│   ├── IMINT (Imagery Intelligence)
│   ├── SIGINT (Signals Intelligence)
│   └── ELINT (Electronic Intelligence)
├── Communication
│   ├── MILSATCOM (Strategic)
│   └── Tactical SATCOM
├── Navigation
│   ├── GPS (US)
│   ├── GLONASS (Russia)
│   ├── Galileo (EU)
│   └── BeiDou (China)
└── Early Warning
    ├── SBIRS (Space-Based Infrared)
    └── DSP (Defense Support Program)
```

### 2. Orbital Parameters

```
Orbit Types:
- LEO (Low Earth Orbit): 160-2,000 km
- MEO (Medium Earth Orbit): 2,000-35,786 km
- GEO (Geostationary): 35,786 km
- HEO (Highly Elliptical): Molniya, Tundra
```

### 3. Key Formulas

#### Orbital Velocity
```
v = √(GM / r)
```

Where:
- `v` = Orbital velocity (m/s)
- `G` = Gravitational constant (6.674 × 10⁻¹¹ m³/kg·s²)
- `M` = Earth mass (5.972 × 10²⁴ kg)
- `r` = Orbital radius (m)

#### Orbital Period
```
T = 2π√(r³ / GM)
```

## 🔧 Components

### TypeScript SDK

```typescript
import {
  calculateOrbitalVelocity,
  validateSatelliteLink,
  encryptDownlink,
  trackSatellitePosition
} from '@wia/def-010';

// Calculate orbital velocity for LEO satellite
const velocity = calculateOrbitalVelocity({
  altitude: 550000, // 550 km
  orbitalType: 'leo'
});

// Validate satellite communication link
const linkStatus = validateSatelliteLink({
  satelliteId: 'SAT-001',
  groundStation: 'GS-KOREA-01',
  frequency: 8.0e9, // 8 GHz X-band
  encryptionLevel: 'aes-256'
});

console.log(linkStatus.isValid, linkStatus.signalStrength);
```

### CLI Tool

```bash
# Calculate orbital parameters
wia-def-010 calc-orbit --altitude 550 --type leo

# Validate satellite link
wia-def-010 validate-link --sat SAT-001 --station GS-01

# Track satellite position
wia-def-010 track --sat SAT-001 --duration 90

# Generate encryption keys
wia-def-010 generate-keys --level aes-256 --purpose downlink
```
