RINEX File Statistics / Information¶
Observations Statistics¶
The -stk_only or -stk_obs outputs observations statistics information to STDOUT. Only the nonzero (nonempty) data values are counted.
You can store it into a file using the -fout command line parameter.
Here is an example for the observations file sin12290.14o:

ASCII Time plot of Observables¶
The -stk_epo command line parameter can be used to create an ASCII time plot to show the availability of observations per PRN (std.) and/or observation type.
In the simplest mode, one has to provide the time bin to be used in seconds (here 1800).

Timeplot per PRN and/or Observation Type¶
A timeplot per observation type is available, providing the [:[prn/otp]] parameter list. This can be combined with other parameters like -smp, -satsys, --obs_types, -prn, -no_prn etc.

Using an editor that is able to scroll horizontally through a text file (nedit for Unix, or Notepad++ for MS Windows)one can visually check data availability details down to a single observation in case of problems. Here is an example of an input file with 5 s sampling rate:
