Question

Dear gpstk team

I have success install gpstk 1.5 under windows vista. I using cygwin to execute gpstk command. I have read the gps tool kit user guide. I processing rinex obs to study ionospheric disturbance ( small scale disturbance, like MSTID ( medium scale ionospheric disturbance)). To do that I extrack L1 L2 from rinex obs (at least 4 station GPS (network) in simultenous time)) by using RinexDump. but first ,I have to fix the cycle slip, then I using DiscFix command: for example ( this comman from user guide):

$ DiscFix --inputfile bant0681.07o --dt 1.5 --Rinexfile bant0681fix.07o

after i perform this command, I got my new rinex ( with fixed cycle slip, ofcourse) bant0681fix.07o, but when I open this file by using notepad, I found there are some epoch is lose. Why this is happen. What is it mean. Is it because of I chose dt 1.5

What the meaning of 1.5, is it default? Is it effect to the range of data? my range data is 30 second. Could I use -dt 30.

Thanks very much for your explanations

best regards

ALERT! If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

if you use the --help option shows:

 --decimate <dt>     Decimate data to time interval (sec) dt

you would want to use dt 30 for your data.
