Decoder/encoder for all RTCM 3 message types up to RTCM 3.3 Amendment 1 (c10403.3).
npm install -S @gnss/rtcm
let buffer: Buffer = ...; // Raw bytes of message to be decoded
let message: RtcmMessage; // Decoded message
let length: number; // Length of decoded message in bytes
[message, length] = RtcmTransport.decode(buffer);
// ...
buffer = buffer.slice(length); // Move to next message
let message = ...; // Message to be encoded
let buffer: Buffer = Buffer.allocUnsafe(RtcmTransport.MAX_PACKET_SIZE);
RtcmTransport.encode(message, buffer);
Messages can be manually constructed using RtcmMessage???.construct({})
, which requires all message properties to be provided.
RtcmMessagePhysicalReferenceStationPosition.construct({
nonPhysicalReferenceStationId: 1,
physicalReferenceStationId: 0,
itrfEpochYear: 0,
arpEcefX: 37927650000,
arpEcefY: -4160650000,
arpEcefZ: 50938770000
})
Transform streams to convert from RtcmMessage
s 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.
