RTCM3 Package

A comprehensive Go implementation of the RTCM 3.x standard for GNSS data transmission. This package provides encoding, decoding, and manipulation of RTCM3 messages with support for multiple GNSS systems including GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS.

Features

  • Complete RTCM3 Message Support: All standard RTCM3 message types (1001-1230)
  • Multi-GNSS System Support: GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS
  • Generic MSM Implementation: Efficient handling of Multiple Signal Messages (MSM1-MSM7)
  • Legacy Encoder/Decoder: Support for traditional RTCM3 messages (1004, 1012)
  • Modern Architecture: Registry pattern with Go generics for extensibility
  • Comprehensive Testing: Full test coverage with real-world data samples
  • Type Safety: Strong typing with compile-time validation

Quick Start

Basic Usage
package main

import (
    "fmt"
    "gitlab.com/earthscope/gnsstools/pkg/encoding/rtcm/rtcm3"
)

func main() {
    // Read RTCM3 data from a file or network stream
    data := []byte{/* RTCM3 binary data */}
    
    // Deserialize the message
    msg, err := rtcm3.DeserializeMessage(data)
    if err != nil {
        panic(err)
    }
    
    // Check message type
    switch msg.Number() {
    case 1004:
        // GPS L1&L2 observations
        fmt.Printf("GPS observations: %+v\n", msg)
    case 1012:
        // GLONASS L1&L2 observations  
        fmt.Printf("GLONASS observations: %+v\n", msg)
    case 1077:
        // GPS MSM7 message
        fmt.Printf("GPS MSM7: %+v\n", msg)
    }
    
    // Serialize back to binary
    serialized := msg.Serialize()
    fmt.Printf("Serialized %d bytes\n", len(serialized))
}
Working with Epochs
import (
    "gitlab.com/earthscope/gnsstools/pkg/encoding/rtcm/rtcm3"
    "gitlab.com/earthscope/gnsstools/pkg/common/gnss/observation"
)

// Create a new epoch with observations
epoch := observation.NewEpoch()

// Add GPS observations
epoch.AddObservation(observation.Observation{
    System: gnss.GPS,
    SatelliteID: 5,
    Code: gnss.L1C,
    Range: 21392193.658,
    Phase: 112416779.880,
    SNR: 49.8,
})

// Encode to RTCM3
encoder := rtcm3.NewLegacyEncoder(time.Second)
rtcmData, err := encoder.Encode(epoch)
if err != nil {
    panic(err)
}

Architecture

Message Types

The package supports all RTCM3 message categories:

  • Antenna Information: 1005, 1006, 1007, 1008, 1009, 1010, 1011, 1013
  • Station Coordinates: 1005, 1006
  • GPS Observations: 1001, 1002, 1003, 1004
  • GLONASS Observations: 1009, 1010, 1011, 1012
  • Galileo Observations: 1042, 1044, 1045, 1046
  • BeiDou Observations: 1047, 1048, 1049, 1050
  • QZSS Observations: 1041, 1043
  • SBAS Observations: 1033
  • Multiple Signal Messages (MSM): 1071-1127
  • State Space Representation (SSR): 1057-1068
  • Network RTK: 1230
Generic MSM Implementation

The package uses Go generics to efficiently handle MSM messages:

// Generic MSM structure
type MessageMsm[S, D any] struct {
    MsmHeader
    SatelliteData S
    SignalData    D
}

// MSM1 example
type MessageMsm1 struct {
    MessageMsm[SatelliteDataMsm1, SignalDataMsm1]
}
Registry Pattern

Messages are registered using a flexible registry pattern:

// Each message type registers itself
func init() {
    RegisterMessage(1004, func(payload []byte) (Message, error) {
        return DeserializeMessage1004(payload), nil
    })
}
