Pardon my ignorance regarding the issue ... for I have no idea where to start looking.

I have moderate experience using matlab, but only in "simple" applications (not saying the
applications were simple, but the type, where you put the input in and out comes the results).

Now, some of my coleagues got an idea - could we use matlab for this what follows ?
---
We're in need to do some measuring. We're using a laptop, with a portable gps device connected by an
usb. It gives us nmea data, in a text file which is updated as the device is working with a certain
frequency of update.

Is it possible for matlab to read those data while gps is working and do some plots in realtime (or,
with a small enough lag) ?

How would one go about doing something like that ?
(not asking for a "solution", but more if you could just point me in the general direction as to
where to start learning about it).

with regards to all,

Paul

Yes, you can use MATLAB for this type of application. Please have a look
at our data acquisition products:

"In a single environment, you can build flexible test systems, automate
testing routines, perform design verification, and analyze and visualize
live data as you collect it."
