RTCM 3 Decoder/Encoder

Decoder/encoder for all RTCM 3 message types up to RTCM 3.3 (c10403.3).

Basic Usage

Decoding

let buffer: Buffer = ...; // Raw bytes of message to be decoded
let message: RtcmMessage = RtcmTransport.decode(buffer);

Encoding

let message = ...; // Message to be encoded
let buffer: Buffer = Buffer.allocUnsafe(RtcmTransport.MAX_PACKET_SIZE);
RtcmTransport.encode(message, buffer);

Streams

Built in transform streams to convert from RtcmMessages to raw bytes and vice-versa.

let input: stream.Readable = ...;
let output: stream.Writable = ...;
input                                      // Stream of raw data
    .pipe(new RtcmDecodeTransformStream()) // Stream of RtcmMessage objects
    .pipe(new RtcmEncodeTransformStream()) // Stream of (identical) raw data
    .pipe(output);

RtcmDecodeTransformStream can optionally synchronize with the raw data stream e.g. if it starts receiving data from the middle of a message.
