libntrip-swift: A modern, high-performance Swift implementation of the NTRIP (Networked Transport of RTCM via Internet Protocol) protocol.

libntrip-swift is a Swift 6 port and evolution of the original Orientable AI internal project. It provides a type-safe, asynchronous framework for streaming Global Navigation Satellite System (GNSS) correction data.

Features

• NTRIP Client: Connect to Casters to receive real-time RTCM streams.
• NTRIP Server: Push GNSS data from local sources (files, stdin) to Casters.
• RTCM3 Parser: High-efficiency bit-level parsing for RTCM3 messages (Types 1005, 1006, 1019, etc.).
• Modern Swift Architecture:
  • Structured Concurrency: Native async/await and AsyncStream support.
  • Cross-Platform: Designed for Linux and macOS using portable POSIX networking.
  • Type Safety: Robust error handling and type-safe configuration via Codable.
• CLI Tools: Ready-to-use ntrip-client and ntrip-server executables.

Project Structure

• Sources/NTRIP: Core protocol implementation, asynchronous sockets, and shared utilities.
• Sources/RTCM3: Message synchronization logic, CRC24 validation, and bit-level field extraction.
• Sources/NTRIPClient: Command-line interface for the NTRIP client.
• Sources/NTRIPServer: Command-line interface for the NTRIP server.
