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.
