Using LabView (Output to file function) to retrieve GPS RMC data

[Ohm Man]

Hello Everyone,

I was wondering if anyone knows the process of getting the RMC data from a GPS unit into a labview file.

I already have it being processed by the program, and now I need to acquire the data and put it into a file where I can analyze it. The tricky part for me is getting it into a file (speed, directional properties, latitude and longitude) and organised so that I can shove it into excel and do my calculations there.

If anyone has any tips or answers, it would be greatly appreciated 🙂

If you can interface to the GPS unit, it should not be problem to write data to a ASCII file. Are you using a RS232 link then communication with your GPS?

Then the data is in the computer you have several options for parsing the string. A RMC data may lock something like this $GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A The first thing to do is to create an array of strings using the

 "Spreadsheet String To Array Function" and "," as the delimiter
