GPS

GPS (Global Positioning System) receivers use satellite data to calculate their location. Logger Pro can collect latitudes, longitudes, and altitudes from a GPS receiver in two ways (see www.vernier.com for a list of supported models):


Collecting live data with Logger Pro

You can take a laptop computer outside with a GPS attached and collect data in real time.

  1. Power up your GPS receiver and establish a satellite connection.
  2. Connect the GPS to the computer.
  3. Select Connect Interface GPS from the Experiment menu. The GPS icon will appear on the toolbar. Live latitude, longitude, and altitude data will be displayed on the computer screen.
  4. Data collection is set to a rate of 1 sample per second for 10 seconds by default.
  1. Click Collect to begin collecting data.


Remote Data Collection

You may want to collect data with your GPS receiver and import the data into Logger Pro at a later time.

  1. Collect a Waypoint, Track, or Route on your GPS receiver. See the User’s Manual for your GPS for detailed instructions.
Note: Logger Pro will not import names assigned to waypoints, rather, it will import its default number.

Note: If you wish to retrieve a Track with its associated times, do not save it. Times can be retrieved only from the Active Log.  
  1. Turn on your GPS and connect it to your computer.
  2. Select Connect Interface GPS from the Experiment menu. If the GPS device contains data, the following dialog will appear.


You can choose any of the following options:

Cancel - The connection will be terminated
No - Select this option if you wish to proceed to data collection.


If you choose Yes, the following window will appear:


  1. Select one of the following options:

OK - Retrieve Remote Data into the Current Document... The data will be retrieved in a default file.

OK - Retrieve Remote Data into a Chosen File... Import the data into a previously customized and saved file.

Logger Pro cannot clear the GPS of data, so Make Data Available for Multiple Retrievals is not needed and therefore greyed out.

  1. The following dialog will appear

  1. Select the type of data you wish to retrieve, then choose the specific data set. You may select multiple Waypoints, but only one Track or Route at a time.
  2. Click OK and the data will be retrieved.

 

Exporting GPS Data

After collecting or importing GPS data, you can export the data in two ways:
