Description

The daa tool performs a data availability analysis of the input data. In general, availability is determined by station and satellite position. In general, availability is determined by station and satellite position.

Usage

DataAvailabilityAnalysisManual [options]

Required Arguments:
Short Arg. Long Arg. Description
-e --eph <inputfile> Where to get ephemeris data. Acceptable formats include RINEX nav, FIC, MDP, SP3, YUMA, and SEM. Repeat for multiple files.
-o -obs <inputfile> Where to get the observation data. Acceptable formats include RINEX obs, MDP, smooth, Novatel, and raw Ashtech. Repeat for multiple files. If a RINEX obs file is provided, the position will be taken from the header unless otherwise specified.

Optional Arguments:
Short Arg. Long Arg. Description
-d --debug Increase debug level.
-v --verbose Increase verbosity.
-h --help Print help usage.
  --output <outputfile> Output location (default is stdout.)
-x --independent The independent variable in the analysis. The default is time.
-c --msc Station coordinates file.
-m --msid Station for which to process data. used to select a station position from the msc file.
-t --time-format CommonTime format specifier used for times in the output. The default is "%Y %j %02H:%02M:%04.1f".
  --mask-angle Ignore anomalies on SVs below this elevation (default is 10 degrees).
  --track-angle Assume the receiver starts tracking at this elevation (default is 10 degrees).
  --time-mask Ignore anomalies on SVs that haven't been above the mask angle for this number of seconds. The default is 0 seconds.
  --snr Discard data with an SNR less than this value. The default is 20 dB-Hz.
-p --position Receiver antenna position in Position (x,y,z) coordinates. Format as a string: "X Y Z".
-l --time-span How much data to process, in seconds.
  --ignore-prn Specify the PRN of a SV to not report on in the output. Repeat to specify multiple SVs.
  --obs-interval Specify the tiem interval, in seconds, between observations. The default is to scan the file to discover this via examination of the file.
-b --bad-health Ignore anomalies associated with SVs that are marked unhealthy.
-s --smash-adjacent Combine adjacent lines from the same PRN.
  -start-time <TIME> Ignore data before this time: %4Y/$3j/%02H:%02M:%05.2f.
  -stop-time <TIME> Ignore any data after this time.
