System Documentation

What problem does it solve?

Provides up-to-date protocol knowledge and parsing guidance to avoid stale GNSS corrections, broken NTRIP connections, and incorrect RTCM3 frame handling that lead to RTK failures.

Core Features & Use Cases

  • Frame parsing: Detailed byte-level layout for RTCM3 frames including preamble, 10-bit length extraction, payload decoding, and CRC-24Q verification.
  • Message semantics: Explanation of MSM vs legacy observations, MSM subtype recommendations (MSM4/MSM7), and common message type ranges for GPS, GLONASS, Galileo, BDS, and others.
  • NTRIP guidance: Differences between NTRIP v1 and v2, authentication, sourcetable usage, and VRS/GGA requirements for client implementations.
  • Operational notes: SSR phase summaries, timestamp alignment fixes for 1 ms issues, and practical rules for choosing message formats in RTK/PPP workflows.

Quick Start

Parse the incoming RTCM3 byte stream, validate the CRC-24Q, extract the 12-bit message type, and choose MSM or legacy handling to determine how to interpret the payload.
