<a name="gdbus-interface-org-freedesktop-ModemManager1-Modem-Location"></a><h2>Description</h2>
<p>      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.
</p>
<p>      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).

<p>        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.
</p>
<p>        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
        <em class="parameter"><code>signal_location</code></em> argument can be set to <code class="constant">FALSE</code> to disable location
        updates via D-Bus signals and require applications to call
        authenticated APIs (like

              Devices supporting this capability return
              a string containing one or more NMEA sentences (D-Bus signature <code class="literal">'s'</code>).
              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 (<code class="literal">&lt;CR&gt;&lt;LF&gt;</code>) sequence.
            </p>
<p>
              For example, if the device sends a <code class="literal">$GPRMC</code> sentence immediately
              followed by a <code class="literal">$GPGGA</code> sentence, the reported location string would be
              (where of course the <code class="literal">&lt;CR&gt;&lt;LF&gt;</code> is replaced with the actual
              ASCII <code class="literal">CR</code> (0x0D) and <code class="literal">LF</code> (0x0A) control characters):
              </p>
<p><code class="literal">
                $GPRMC,134523.92,V,,,,,,,030136,,,N*73&lt;CR&gt;&lt;LF&gt;$GPGGA,,,,,,0,00,0.5,,M,0.0001999,M,0.0000099,0000*45
              </code></p>
<p>
              If the device sends a new <code class="literal">$GPRMC</code> three seconds later, the new <code class="literal">$GPRMC</code>
              replaces the previously received <code class="literal">$GPRMC</code> sentence, and the updated
              string would be:
              </p>
<p><code class="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
              </code></p>
<p>
              If the device then sends a <code class="literal">$GPGSA</code> sentence about 5 seconds later, the
              <code class="literal">$GPGSA</code> sentence is added to the string (since no <code class="literal">$GPGSA</code> sentence was
              obviously received in this session), the updated string would be:
              </p>
<p><code class="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
              </code></p>
<p>
              The manager may discard any cached sentences older than 30 seconds.
            </p>
<p>
              This allows clients to read the latest positioning data as soon as
              possible after they start, even if the device is not providing
              frequent location data updates.
