Dear Teqc (and GPS) users,

 

Perhaps you have encountered something similar in the past:

We have installed a Trimble NetRS receiver as a permanent station at Cabo

The output of SUM line of TEQC looks like this:

I am having problems with the anonymous ftp, where I wanted to deposit the
files. I can e-mail the rnx file as an attachment if any of you would like
to have a closer look at it.

 

Any suggestions?

 

Thanks a lot!

 

Gia
