       @short_description: The ModemManager Location interface.

       The Location interface allows devices to provide location information to
       client applications. Not all devices can provide this information, or even
       if they do, they may not be able to provide it while a data session is
       active.

       This interface will only be available once the modem is ready to be
       registered in the cellular network. 3GPP devices will require a valid
       unlocked SIM card before any of the features in the interface can be
       used (including GNSS module management).

         Setup:

         @signal_location: Flag to control whether the device emits signals with the new location information. This argument is ignored when disabling location information gathering.

         Configure the location sources to use when gathering location
         information. Also enable or disable location information gathering.
         This method may require the client to authenticate itself.

         When signals are emitted, any client application (including malicious
         ones!) can listen for location updates unless D-Bus permissions restrict
         these signals from certain users. If further security is desired, the
         @signal_location argument can be set to %FALSE to disable location
         updates via D-Bus signals and require applications to call
         authenticated APIs (like
         <link linkend="gdbus-method-org-freedesktop-ModemManager1-Modem-Location.GetLocation">GetLocation()</link>

               Devices supporting this capability return
               a string containing one or more NMEA sentences (D-Bus signature <literal>'s'</literal>).
               The manager will cache the most recent NMEA sentence of each type for
               a period of time not less than 30 seconds.  When reporting multiple
               NMEA sentences, sentences shall be separated by an ASCII Carriage

             </para>
             <para>
               For example, if the device sends a <literal>$GPRMC</literal> sentence immediately
               followed by a <literal>$GPGGA</literal> sentence, the reported location string would be
               (where of course the <literal>&lt;CR&gt;&lt;LF&gt;</literal> is replaced with the actual
               ASCII <literal>CR</literal> (0x0D) and <literal>LF</literal> (0x0A) control characters):

               </literal></para>
               If the device sends a new <literal>$GPRMC</literal> three seconds later, the new <literal>$GPRMC</literal>
               replaces the previously received <literal>$GPRMC</literal> sentence, and the updated
               string would be:
               <para><literal>
                 $GPRMC,134526.92,V,,,,,,,030136,,,N*76&lt;CR&gt;&lt;LF&gt;$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45
               </literal></para>
               If the device then sends a <literal>$GPGSA</literal> sentence about 5 seconds later, the
               <literal>$GPGSA</literal> sentence is added to the string (since no <literal>$GPGSA</literal> sentence was
               obviously received in this session), the updated string would be:
               <para><literal>
                 $GPRMC,134526.92,V,,,,,,,030136,,,N*76&lt;CR&gt;&lt;LF&gt;$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45&lt;CR&gt;&lt;LF&gt;$GPGSA,A,1,,,,,,,,,,,,,1.1,0.5,1.0*34
               </literal></para>
               The manager may discard any cached sentences older than 30 seconds.

             <para>
               This allows clients to read the latest positioning data as soon as

	Devices supporting this capability return
	a string containing one or more NMEA sentences (D-Bus signature <literal>'s'</literal>).
	The manager will cache the most recent NMEA sentence of each type for
	a period of time not less than 30 seconds. When reporting multiple
	NMEA sentences, sentences shall be separated by an ASCII Carriage
	Return and Line Feed (<literal><CR><LF></literal>) sequence.
	</para>
	<para>
	For example, if the device sends a <literal>$GPRMC</literal> sentence immediately
	followed by a <literal>$GPGGA</literal> sentence, the reported location string would be
	(where of course the <literal><CR><LF></literal> is replaced with the actual
	ASCII <literal>CR</literal> (0x0D) and <literal>LF</literal> (0x0A) control characters):
	<para><literal>

	</literal></para>
	If the device sends a new <literal>$GPRMC</literal> three seconds later, the new <literal>$GPRMC</literal>
	replaces the previously received <literal>$GPRMC</literal> sentence, and the updated
	string would be:
	<para><literal>
	$GPRMC,134526.92,V,,,,,,,030136,,,N76<CR><LF>$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,000045
	</literal></para>
	If the device then sends a <literal>$GPGSA</literal> sentence about 5 seconds later, the
	<literal>$GPGSA</literal> sentence is added to the string (since no <literal>$GPGSA</literal> sentence was
	obviously received in this session), the updated string would be:
	<para><literal>
	$GPRMC,134526.92,V,,,,,,,030136,,,N76<CR><LF>$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,000045<CR><LF>$GPGSA,A,1,,,,,,,,,,,,,1.1,0.5,1.0*34

	The manager may discard any cached sentences older than 30 seconds.
