Sidereon.GNSS.RINEX.Observations.Epoch (Sidereon v3.0.0)

Copy Markdown View Source

One epoch record of a RINEX observation product, as Sidereon.GNSS.RINEX.Observations.epochs/1 lists them.

  • index - the zero-based position in the product, which every per-epoch accessor takes.
  • epoch - {{year, month, day}, {hour, minute, second}} in the file's time scale, or nil for an event whose epoch fields are blank. RINEX lets an event without a significant epoch leave them blank; an observation or cycle slip epoch always carries one. No time is made up for an event without one.
  • epoch_picoseconds - the RINEX 4.02 picosecond extension of the epoch line, nil where the line has none. second does not include it.
  • flag - 0 for an observation epoch, 1 after a power failure, 6 for cycle slip records, and any other flag above 1 for an event.
  • rcv_clock_offset_s - the receiver clock offset on the epoch line, seconds, or nil.
  • declared_record_count - the satellite or record count the epoch line declares.
  • sat_count - satellites holding observations; 0 for an event and for a cycle slip epoch.
  • cycle_slip_count - satellites holding cycle slips; non-zero only for a flag 6 epoch. The slips are read with Sidereon.GNSS.RINEX.Observations.cycle_slips/3.
  • special_records - the records an event epoch carried, verbatim, in order. Header records among them take effect from this epoch; see Sidereon.GNSS.RINEX.Observations.header_at/2.
