LabVIEW program that can show longitude and latitude information of my USB gps sensor in real time?

Help: I am looking for a labView program that can show longitude and latitude information  of my USB gps sensor in real time in google maps?

You can pay someone here to do it.  Else, you can whip up some code and ask for help here.

Hi,

I have done something similar 4 years ago. Although i don't remember exactly how, i think at that time i had embedded the google maps webpage on the labview front panel using activex. You can use the google maps URL formats for plotting a specific latitude,longitude combination. This would appear correctly in the labview front panel.

However you have to figure out how you are going receive the latitude and longitude info on your pc. For my system i used a gprs modem attached to the gps unit and an arduino to upload the location information to a file located in an online FTP sever. The pc program would periodically read this info from the online server.

I am sure there are even better methods available for communicating over internet. Hope you find something suitable.

good luck!

this error occurs when trying to decode a GPS message i dont know what to do can anybody give some help ?  LabVIEW An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as or @.

How do you think we can help you? We have neither seen your LabVIEW program nor did you tell us anything about what sensor you try to use other than that is connected through USB. But USB is just a cable and connector. What information is transmitted over it, how and in which format depends totally on the device involved.

Your sensor MIGHT implement a virtual serial port in which case it would appear as COM port in Windows and you can access it through VISA functions in LabVIEW. It might just as well be a HID device class (not the most logical choice but who cares about such details, many manufacturers definitely don’t) and then there is no built in method in LabVIEW to communicate it. It could, and even often does use a proprietary USB device class protocol and then you can only communicate to it if you have a device driver from the manufacturer or the protocol description to write your own device driver.

Without seeing your code we cannot tell you what you are doing wrong!

As for parsing GPS sentences (you are just parsing Strings), here's a good place to start

Most GPS modules I used had 5V or 3.3V serial data interface and I used a common FTDI serial to USB adapter to interface it using VISA. The GPS was then just like any other instrument on a Com port.
