# SkyView Project Guidelines
|
||||
|
||||
## Documentation Requirements
|
||||
- We should always have an up to date document describing our architecture and features
|
||||
- Include links to any external resources we've used
|
||||
- We should also always have an up to date README describing the project
|
||||
- Shell scripts should be validated with shellcheck
|
||||
- Always make sure the code is well documented with explanations for why and how a particular solution is selected
|
||||
|
||||
## Development Principles
|
||||
- An overarching principle with all code is KISS, Keep It Simple Stupid
|
||||
- We do not want to create code that is more complicated than necessary
|
||||
- When changing code, always make sure to update any relevant tests
|
||||
- Use proper error handling - aviation applications need reliability
|
||||
|
||||
## SkyView-Specific Guidelines
|
||||
|
||||
### Architecture & Design
|
||||
- Multi-source ADS-B data fusion is the core feature - prioritize signal strength-based conflict resolution
|
||||
- Embedded resources (SQLite ICAO database, static assets) over external dependencies
|
||||
- Low-latency performance is critical - optimize for fast WebSocket updates
|
||||
- Support concurrent aircraft tracking (100+ aircraft should work smoothly)
|
||||
|
||||
### Code Organization
|
||||
- Keep Go packages focused: beast parsing, modes decoding, merger, server, clients
|
||||
- Frontend should be modular: separate managers for aircraft, map, UI, websockets
|
||||
- Database operations should be fast (use indexes, avoid N+1 queries)
|
||||
|
||||
### Performance Considerations
|
||||
- Beast binary parsing must handle high message rates (1000+ msg/sec per source)
|
||||
- WebSocket broadcasting should not block on slow clients
|
||||
- Memory usage should be bounded (configurable history limits)
|
||||
- CPU usage should remain low during normal operation
|
||||
|
||||
### Documentation Maintenance
|
||||
- Always update docs/ARCHITECTURE.md when changing system design
|
||||
- README.md should stay current with features and usage
|
||||
- External resources (ICAO docs, ADS-B standards) should be linked in documentation
|
||||
- Country database updates should be straightforward (replace SQLite file)

SkyView automatically loads `config.json` from the current directory, or you can specify a path with `SKYVIEW_CONFIG`.
|
||||
```bash
|
||||
# Single source
|
||||
./skyview -sources "primary:Local:localhost:30005:51.47:-0.46"
|
||||
|
||||
Create a `config.json` file (see `config.json.example`):
|
||||
# Multiple sources
|
||||
./skyview -sources "site1:North:192.168.1.100:30005:51.50:-0.46,site2:South:192.168.1.101:30005:51.44:-0.46"
|
||||
|
||||
# Using configuration file
|
||||
./skyview -config config.json
|
||||
```
|
||||
|
||||
### Using Debian Package
|
||||
|
||||
```bash
|
||||
# Install
|
||||
sudo dpkg -i skyview_0.0.2_amd64.deb

||||
|
||||
# Configure
|
||||
sudo nano /etc/skyview/config.json
|
||||

// Package assets provides embedded static web assets for the SkyView application.
|
||||
//
|
||||
// This package uses Go 1.16+ embed functionality to include all static web files
|
||||
// directly in the compiled binary, eliminating the need for external file dependencies
|
||||
// at runtime. The embedded assets include:
|
||||
// - index.html: Main web interface with aircraft tracking map
|
||||
// - css/style.css: Styling for the web interface
|
||||
// - js/app.js: JavaScript client for WebSocket communication and map rendering
|
||||
// - icons/*.svg: Type-specific SVG icons for aircraft markers
|
||||
// - favicon.ico: Browser icon
|
||||
//
|
||||
// The embedded filesystem is used by the HTTP server to serve static content
|
||||
// and enables single-binary deployment without external asset dependencies.

import "embed"
|

|

// Static contains all embedded static web assets from the static/ directory.
|
||||
//
|
||||
// Files are embedded at build time and can be accessed using the standard
|
||||
// fs.FS interface. Path names within the embedded filesystem preserve the
|
||||
// directory structure, so files are accessed as:
|
||||
// - "static/index.html"
|
||||
// - "static/css/style.css"
|
||||
// - "static/js/app.js"
|
||||
// - etc.
|
||||
//
|
||||
// This approach ensures the web interface is always available without requiring
|
||||
// external file deployment or complicated asset management.

|
||||
.SH DESCRIPTION
|
||||
beast-dump is a command-line utility for analyzing and decoding ADS-B
|
||||
(Automatic Dependent Surveillance-Broadcast) data stored in Beast binary
|
||||
format. It can read from files or connect to Beast format TCP streams
|
||||
to decode and display aircraft messages.
|
||||
.PP
|
||||
The Beast format is a compact binary representation of Mode S/ADS-B
|
||||
messages commonly used by dump1090 and similar software-defined radio
|
||||
applications for aircraft tracking.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||

.SH EXAMPLES
|
||||
.TP
|
||||
Analyze Beast format file:
|
||||
.B beast-dump data.bin
|
||||
.TP
|
||||
Connect to live Beast stream:
|
||||
.B beast-dump \-host localhost \-port 30005
|
||||
.TP
|
||||
Export to JSON format with statistics:
|
||||
.B beast-dump \-format json \-stats data.bin
|
||||
.TP
|
||||
Filter messages for specific aircraft:
|
||||
.B beast-dump \-filter A1B2C3 \-verbose data.bin
|
||||
.TP
|
||||
Process only first 1000 messages as CSV:
|
||||
.B beast-dump \-format csv \-count 1000 data.bin
|
||||
.SH OUTPUT FORMAT
|
||||
The default text output shows decoded message fields:
|
||||
.PP
|
||||
.nf
|
||||
ICAO: A1B2C3 Type: 17 Time: 12:34:56.789
|
||||

|
||||
2. Configuration file (JSON)
|
||||
3. Default values (lowest priority)
|
||||
|
||||
### Configuration Structure
|
||||
```json
|
||||
{
|
||||
"server": {
|
||||
"host": "", // Bind address (empty = all interfaces)
|
||||
"port": 8080 // HTTP server port
|
||||
},
|
||||
"sources": [
|
||||
{
|
||||
"id": "unique-id", // Source identifier
|
||||
"name": "Display Name", // Human-readable name
|
||||
"host": "hostname", // Receiver hostname/IP
|
||||
"port": 30005, // Beast format port
|
||||
"latitude": 51.4700, // Receiver location
|
||||
"longitude": -0.4600,
|
||||
"altitude": 50.0, // Meters above sea level
|
||||
"enabled": true // Source enable/disable
|
||||
}
|
||||
],
|
||||
"settings": {
|
||||
"history_limit": 500, // Max trail points per aircraft
|
||||
"stale_timeout": 60, // Seconds before aircraft removed
|
||||
"update_rate": 1 // WebSocket update frequency
|
||||
},
|
||||
"origin": {
|
||||
"latitude": 51.4700, // Map center point
|
||||
"longitude": -0.4600,
|
||||
"name": "Origin Name"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Concurrency Model
|
||||
- **Goroutine per Source**: Each Beast client runs in separate goroutine
|
||||
- **Mutex-Protected Merger**: Thread-safe aircraft state management
|
||||
- **WebSocket Broadcasting**: Concurrent client update distribution
|
||||
- **Non-blocking I/O**: Asynchronous network operations
|
||||
|
||||
### Memory Management
|
||||
- **Bounded History**: Configurable limits on historical data storage
|
||||
- **Automatic Cleanup**: Stale aircraft removal to prevent memory leaks
|
||||
- **Efficient Data Structures**: Maps for O(1) aircraft lookups
|
||||
- **Embedded Assets**: Static files bundled in binary
|
||||
|
||||
### Scalability
|
||||
- **Multi-source Support**: Tested with 10+ concurrent receivers
|
||||
- **High Message Throughput**: Handles 1000+ messages/second per source
|
||||
- **Low-latency Updates**: Sub-second latency for aircraft updates
|
||||
- **Responsive Web UI**: Optimized for 100+ concurrent aircraft
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Network Security
|
||||
- **No Authentication Required**: Designed for trusted network environments
|
||||
- **Local Network Operation**: Intended for private receiver networks
|
||||
- **WebSocket Origin Checking**: Basic CORS protection
|
||||
|
||||
### System Security
|
||||
- **Unprivileged Execution**: Runs as non-root user in production
|
||||
- **Filesystem Isolation**: Minimal file system access required
|
||||
- **Network Isolation**: Only requires outbound TCP to receivers
|
||||
- **Systemd Hardening**: Security features enabled in service file
|
||||
|
||||
### Data Privacy
|
||||
- **Public ADS-B Data**: Only processes publicly broadcast aircraft data
|
||||
- **No Personal Information**: Aircraft tracking only, no passenger data
|
||||
- **Local Processing**: No data transmitted to external services
|
||||
- **Historical Limits**: Configurable data retention periods

// Package beast provides Beast binary format parsing for ADS-B message streams.
|
||||
//
|
||||
// The Beast format is a binary protocol developed by FlightAware and used by
|
||||
// dump1090, readsb, and other ADS-B software to stream real-time aircraft data
|
||||
// over TCP connections (typically port 30005).
|
||||
//
|
||||
// Beast Format Structure:
|
||||
// - Each message starts with escape byte 0x1A
|
||||
// - Message type byte (0x31=Mode A/C, 0x32=Mode S Short, 0x33=Mode S Long)
|
||||
// - 48-bit timestamp (12MHz clock ticks)
|
||||
// - Signal level byte (RSSI)
|
||||
// - Message payload (2, 7, or 14 bytes depending on type)
|
||||
// - Escape sequences: 0x1A 0x1A represents literal 0x1A in data
|
||||
//
|

// This package handles:
|
||||
// - Binary message parsing and validation
|

// - Timestamp and signal strength extraction
|

// - Escape sequence processing
|

// - ICAO address and message type extraction
|
||||
// - Continuous stream processing with error recovery
|
