gpsdata 0.4.3

• Use ''.ljust() to pad to 80 spaces instead of formatting operation
• Disable command-line option "-p" for pickling, since it's broken.
• Added unused "line" argument to gpsdata.showwarn() to avoid Python 2.6
  warning
• Added README
• If matplotlib is not available, disable the "-i" plotting option in
  readfile.py command-line usage, rather than crashing (which also
  prevented in-Python usage of read_file())

gpsdata 0.4.2

• Was misreading years with all four digits present
• Wow, backticks are better than str()!
• Changes to operate with mod_python (Juan Carlos Espinoza):
  • Added readfile.index() function
  • Special behaviour in plotter.plot if fname == 'web'
• Python 2.4 compatibility:
  • Remove str.rpartition() in readfile
  • Remove try-except-finally in gpstime
  • Remove conditionals (x if foo else y)
  • Replace datetime.strptime with time.strptime in gpstime
  • Remove epilog from readfile OptionParser (wasn't up to date anyway)
  • Add rinex.header.field.__deepcopy__ (2.4 barfed on function references)
• Remove plotter.MarkerNames class, just leave in the module
  (I am too class-crazy)
• Add plotter.colorplot() to plot lines with meaningfully colored dots
• Make system-determined leap seconds ints, not timedeltas (so that
  comparison with header-derived leap seconds is not bogus)
• Record filename in metadata, report in header summary

gpsdata 0.4.1

• Read marker name –> location title information from stations.dat
  (also contains station coordinates, potentially useful elsewhere)
• Command line: When specifying --image without --output,
  • We were calling plot() with a nonexistent variable
  • We were using fig.show() for display, which is not in all matplotlib backends
    (replaced by matplotlib.pyplot.show())

gpsdata 0.4

• Create plotter.py module with function, plot(), to plot a given
  observation for all satellites, outputting to given filename
  (extension determines format) (using matplotlib)
• Split gpsdata.iter() to gpsdata.iterdict() and gpsdata.iterlist()
• Eliminate gpsdata.iterepochs() in favor of gpsdata.iterlist('epoch')
  or gpsdata.iterdict('epoch')
• Create utility.py module for "useful" classes that didn't belong in
  gpsdata or readfile: value, listvalue, fileread so far
  • This fixes a recursive dependency problem in import readfile
• Comply PEP 8
  • Hence renamed package from GPSData to gpsdata
    • So main class is now gpsdata.gpsdata.GPSData
• Count number of header sections in RINEX file
• Track "phase connected arcs", i.e. periods between cycle slips, for
  each satellite.
  • New functions in gpsdata.GPSData: breakphase, checkphase, sanearcs
• RINEX: numrec in event flag 5 observation header indicates header lines
  following; process them.
  • Since "epoch is significant" for flag 5, mark these header values
    with the epoch.
  • While I'm at it, mark all header values with the record number
    and line number.
  • Also mark records between flag 2 (start moving) and flag 3 (stop) as
    "in motion."
• Correctly consume any PRN list continuation lines for event flag 6
  (Cycle Slip Records, which we ignore.)

GPSData 0.3.1

• Fix operation for tarfiles (was using nonexistent next()):
  Introduce readfile.fileread class to wrap various file-like objects
• record.ptec(prn) returns (uncorrected, instantaneous, slant) phase TEC.
  record.ctec(prn) returns code TEC
• Include leap seconds, observation interval in header summary

GPSData 0.3

• Don't crash on unknown format input files
• Output comments in header summary
• Fix bug in gpsdatetime vs. datetime equality comparison
• Check or supply leap seconds header info when a leap second occurs during the observations
• Nicer warning output
• Fix bug introduced since 0.2 in handling multiple files
• Implement Compact RINEX processing in rinex.py, remove crx2rnx (eliminates platform dependency on Linux x86)
• Rename GPSData.rnx to GPSData.meta in lame attempt to appear less RINEX-dependent
• Forgive incorrect spacing in RINEX header labels
• Split out readfile.py, added support for multiple formats (currently only RINEX available)
• Determine interval of observations (for comparison with header)
• GPSData.sats() returns set of satellite PRNs in this data
• GPSData.iter() allows iteration over a given satellite, observation code, or both; GPSData.iterepochs() iterates over record epochs
• Fix gpsdatetime unpickling
• Friendlier error for nonexistent files
• 2-digit years disambiguated correctly in absence of FIRST/LAST OBS
  (80-99 -> 1980-1999, 00-79 -> 2000-79)

GPSData 0.2

• Use standard Python datetime for time data, not a home-grown struct
  • Correctly deal with GPS, GLONASS (UTC), Galileo (TAI) time systems
  • Include gpstime.py with useful time zones, leapseconds data
  • gpstime.gpsdatetime is a datetime class allowing UTC offsets which are
    not whole minutes
  • 2-digit years disambiguated by TIME OF FIRST/LAST OBS
• Command-line call to rinex.py outputs header info
• rinex.get_data() tracks some header stats and adds or verifies them

GPSData 0.1

Initial release.
