Answer: Yes, you can!  You just need to export your Simcenter Testlab (formerly LMS Test.Lab) GPS data into a KML file.

  

A KML file (or Keyhole Markup Language) contains GPS co-ordinates.  A KML file can be used with Google Earth to visualize the location a measurement was taken with a GPS equipped Simcenter SCADAS data acquisition unit.

Exporting GPS KML File to Google Earth

 

To produce a KML file from Simcenter Testlab, select a measurement containing GPS:

  1. Right click and choose “Export to -> GPS -> KML...”  Name your file.

  2. Double click on the KML file to open in Google Earth

Setting Up GPS on Simcenter SCADAS

 

GPS data can be recorded on a Simcenter SCADAS in parallel with all other types of channels (ie, accelerometers, microphones, strain gauges, etc) in Simcenter Testlab Signature:

 

  • Insert the GPS antenna into the appropriate connector on your Simcenter SCADAS.  Note: In a motor vehicle, the antenna receiver can be placed on a dashboard to properly see satellites.  It is not necessary to put it on the roof and run the cable through a door, despite the fact that it has a magnetic base.  This can save the antenna cable from being damaged by the opening and closing of the door.

  •  In Simcenter Testlab, on the “Channel Setup” Worksheet, set “Clock Sync:” from “None” to “GPS”

KML File History

 

The KML (Keyhole Markup Language) file is named after Keyhole corporation, which was a commercial spinoff of the CIA.  Google bought Keyhole in 2004.
