ObservationKeyLookup maps a GNSS system and its RINEX 2.11 observation code (e.g. "L2") to a ObservationKey.

Unfortunantly, the RINEX 2.11 observation codes cannot be mapped to RINEX 3&4 observation codes without making assumptions about how the RINEX file was generated. For example, we don't know if the "L2" column contains L2C or L2W values.

Functions

func EncodeObs added in v0.54.0 

func EncodeObs(w io.Writer, epochMap observation.Epoch, settings *Settings) error

func EncodeObsV2 added in v0.54.0 

func EncodeObsV2(w io.Writer, epoch observation.Epoch, settings *Settings) error

EncodeObsV2 writes an observation.Epoch as RINEX 2 to the provided io.Writer interface. This function is highly optimized to produce zero heap allocations per epoch.

func EncodeObsV3 added in v0.54.0 

func EncodeObsV3(w io.Writer, epoch observation.Epoch, settings *Settings) (err error)

EncodeObsV3 writes a observation.EpochMap as RINEX 3 to the provided io.Writer interface.

func EncodeObsV4 added in v0.54.0 

func EncodeObsV4(w io.Writer, epoch observation.Epoch, settings *Settings) (err error)

EncodeObsV4 writes a single observation.Epoch in RINEX 4 format to the provided io.Writer.

The satellites within the epoch are automatically sorted by GNSS system and PRN before writing. The ordering of the observation columns is strictly dictated by the pre-sorted keys in settings.ObservationsBySystem. The selection of measurements to be output (Phase, Range, SNR, Doppler) is controlled by settings.OutputSettings.

This function is highly optimized for performance. It utilizes sync.Pool for buffer management and slice sorting, avoiding the fmt package to achieve zero heap allocations per epoch. Missing observations are automatically padded with blank spaces to conform to the RINEX specification.

type ObsWriter added in v0.50.0 

type ObsWriter struct {
	// contains filtered or unexported fields
}

ObsWriter implements observation.EpochWriter for RINEX observation output.

RINEX headers declare which observation types exist before any epoch data, creating a chicken-and-egg problem for streaming. ObsWriter handles this in two modes:

  • With a pre-configured header (via ObsWriterWithSettings): epochs are written directly as they arrive. Use this for RINEX-to-RINEX conversion where the source header is already known.

  • Without a header: epochs are buffered in memory. On ObsWriter.Flush, the observation types are collected from all buffered epochs, the header is written, then all epochs follow. This is equivalent to the current batch approach but encapsulated inside the writer.

func NewObsWriter added in v0.50.0 

func NewObsWriter(w io.Writer, settings *Settings) *ObsWriter

NewObsWriter creates a buffered RINEX writer. All epochs are held in memory until ObsWriter.Flush is called, at which point the header is derived from the buffered data and written before the epochs. Use ObsWriterWithSettings when the header content is known up front.

func ObsWriterWithSettings added in v0.50.0 

func ObsWriterWithSettings(w io.Writer, settings *Settings) *ObsWriter

ObsWriterWithSettings creates a streaming RINEX writer with a pre-configured header. The header is written on the first call to Write, and epochs stream through without buffering.

func (*ObsWriter) Flush added in v0.50.0 

func (ow *ObsWriter) Flush() error

Flush finalizes the RINEX file. In buffered mode it collects observation types from all epochs, writes the header, then writes all epochs. In streaming mode it is a no-op.

func (*ObsWriter) Write added in v0.50.0 

func (ow *ObsWriter) Write(epoch observation.Epoch) (int, error)

Write writes or buffers a single observation epoch.

type ObservationTypesMap added in v0.50.0

type OutputSettings

	Phase   bool
	Range   bool

NewOutputSettings returns a struct with the default RINEX outputs enabled. Doppler is disabled by default.

func (OutputSettings) CountEnabled 

func (os OutputSettings) CountEnabled() int

type Record added in v0.50.0 

type Record struct {
	Content string
	Label   string
}

Record stores the header lines in a struct splitting the content (60 chars) and the label (20 chars) into two separate strings. Supports versions 2,3,4.

type Scanner 

type Scanner struct {
	*bufio.Scanner
	Header  Header
	Version Version
	Type    string
	System  string
	// contains filtered or unexported fields

Scanner -

func NewScanner 

func NewScanner(r io.Reader) (scanner *Scanner, err error)

NewScanner creates a new RINEX scanner. It reads the header, extracting the version, type and system. Other type and version specific information is extracted in later steps.

CRINEX (Hatanaka-compressed) files are decompressed transparently on the fly.

It is the caller's responsibility to call Close on the underlying reader when done.
