Import the following classes:
- javax.microedition.location.LocationProvider
- javax.microedition.location.Location

Create an instance of a LocationProvider.

LocationProvider provider = new LocationProvider();

Invoke LocationProvider.getLocation() and assign the value that the method returns to a Location variable.
```
Location mylocation = provider.getLocation(-1);
```
Invoke the Location.getExtraInfo() method using the NMEA MIME type as a parameter. The method returns an encoded String that contains information about the number of GPS satellites.
```
String encodedStr = mylocation.getExtraInfo("application/X-jsr179-location-nmea"); 
```
To retrieve the GPS satellite information, parse through the information in the returned String value.
