/**
 * Main SatelliteService implementation, which binds via the Telephony SatelliteServiceController.
 * Services that extend SatelliteService must register the service in their AndroidManifest to be
 * detected by the framework. First, the application must declare that they use the
 * "android.permission.BIND_SATELLITE_SERVICE" permission. Then, the SatelliteService definition in
 * the manifest must follow the following format:
 *
 * ...
 * <service android:name=".EgSatelliteService"
 *     android:permission="android.permission.BIND_SATELLITE_SERVICE" >
 *     ...
 *     <intent-filter>
 *         <action android:name="android.telephony.satellite.SatelliteService" />
 *     </intent-filter>
 * </service>
 * ...
 *
 * The telephony framework will then bind to the SatelliteService defined in the manifest if it is
 * the default SatelliteService defined in the device overlay "config_satellite_service_package".
