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

Copy Markdown View Source

One change Sidereon.GNSS.RINEX.Observations.downgrade_to_rinex2/2 made to turn a product into one a version 2 file states exactly.

tag names the change and decides which of the other fields are set; every field the change does not carry is nil:

  • :code_renamed - system, from_code, to_code: a code became the one its version 2 column reads as.
  • :code_moved - system, code, from_position, to_position: a code moved within its list, its values with it. Positions are zero-based.
  • :code_added - system, code: a code with no values was added so the constellations' lists line up under one list of version 2 names.
  • :code_list_removed - system, codes: a list no version 2 reader would build, since no observation or count names the constellation.
  • :value_rounded - epoch_index, satellite, code, from_value, to_value: an observation rounded to the three decimals its field holds.
  • :cycle_slip_rounded - the same fields, for a cycle slip.
  • :scale_factors_removed - count: the SYS / SCALE FACTOR records, over values that are already physical.
  • :epoch_picoseconds_removed - epoch_index, picoseconds.
  • :clock_offset_rounded - epoch_index, from_value, to_value: a receiver clock offset rounded to the nine decimals of the version 2 field, in seconds.
  • :in_event_lists - epoch_index, change: a change to the code lists in effect from that event epoch, change being another DowngradeChange.
  • :deprecated_records_removed - label, epoch_index, records: the SYS / PHASE SHIFT or GLONASS COD/PHS/BIS records of a product read from RINEX 4, which version 4 declares ignored. epoch_index is nil for the file header.
  • :event_records_rewritten - epoch_index, from_records, to_records: an event's records as they were and as they are now.

message is the core's description of the change.
