Error importing Sentinel-1 external orbits
July 9, 2018 at 11:52 am #3085
Today, when I tried to import a Sentinel-1 dataset and set the orbits I have encountered a few errors, such as:
WARNING: An error occurred Downloading external S1 orbit. Built-in Orbit is used for date 2016/04/29.
!No external orbit available for image 20160429
An error occurred and was saved in the file lasterror.mat, directory D:\SARproz
If you need assistance, please include the file lasterror.mat
You may include also file 09_Jul_2018_19_00_03_sarproz.log
Here a glimpse:
Java exception occurred:
java.net.SocketException: Connection reset by peer: socket write error

I have reinstalled Matlab MCR, and disabled all firewalls, but the problem persits. I know I can download the orbits manually, but since until now I didn’t have any any problems downloading the orbits for the very same dataset, I thought it would be helpful to ask first for some suggestions
I attached also the error file.
Thank you in advance,

Update your software to the newest version first, please.

I have updated my software to the newest version, but unfortunately, the problem persists.

Can you go to your browser and enter the following url:
And see if you can connect. If you can, also try to go into the folder and randomly download a few orbits.
If you cannot connect it means something is still blocking your ftp protocol. If you can connect, then let me know and I will try to understand what is happening.

Thank you for your answer!
I tried connecting to the url and it worked.
I have uninstalled the antivirus to make sure there’s no left firewall on. The one from windows is disabled.
I have attached another type of message I receive when I open the program besides the Java error after I try setting the orbits

Could you please send me the new lasterror.mat and log regarding the orbits downloading issue? – and before that, please update to the newest version of sarproz. I see in the previous log that you are using an old version from September last year. Please make sure you are using the newest version of sarproz.

The software has been updated since I uploaded the document.
These are the new log and lasterror files now:

The FTP site is working well. There is either a network blocking issue (not necessarily from your side) or there also might be a proxy issue (if for any chances you are using a proxy).
I would try to test the following to rule out problems:
1. try to connect using a client, i.e., filezilla, and check if the connection works;
2. If you have matlab, try to use the ftp() command to connect and see if you can connect;
3. Try with another machine with another IP to make sure this is a network problem instead of a software problem.
