/** A combination of GPS receiver + NTRIP receiver capable of submitting GGA
 * frames to enable RTCM 3.0.
  * This class holds instances of two classes, publicly exposed as member
 * variables:
  *  - mrpt::hwdrivers::CGPSInterface  gps;
  *  - mrpt::hwdrivers::CNTRIPEmitter  ntrip;
  *
  * and acts as a "joint sensor", calling both objects' doProcess() inside the
 * doProcess() loop, etc.
  *
  * The goal of this class is automatically gather GGA frames from the gps
 * sensor and upload them to the NTRIP server.
  *
  * Configuration file format is a combination of the original parameters for
 * both classes, each with
  * a prefix: "gps_" for CGPSInterface params and "ntrip_" for CNTRIPEmitter.
  *
  *  \code
  *  PARAMETERS IN THE ".INI"-LIKE CONFIGURATION STRINGS:
  * -------------------------------------------------------
  *   [supplied_section_name]
  *    gps_COM_port_WIN = COM3
  *    gps_COM_port_LIN = ttyS0
  *    gps_baudRate     = 4800   // The baudrate of the communications (typ.
 * 4800 bauds)
  *    gps_pose_x       = 0      // 3D position of the sensed point relative to
 * the robot (meters)
  *    gps_pose_y       = 0
  *    gps_pose_z       = 0
  *    # Other params (see CGPSInterface)
  *
  *    ntrip_COM_port_WIN = COM1         // Serial port where the NTRIP stream
 * will be dumped to.
  *    ntrip_COM_port_LIN = ttyUSB0
  *    ntrip_baudRate     = 38400
  *
  *    ntrip_server   = 143.123.9.129    // NTRIP caster IP
  *    ntrip_port     = 2101
  *    ntrip_mountpoint = MYPOINT23
  *    #ntrip_user = pepe            // User & password optional.
  *    #ntrip_password = loco
  *
  *  \endcode

  *  The next picture summarizes existing MRPT classes related to GPS / GNSS
 * devices (CGPSInterface, CNTRIPEmitter, CGPS_NTRIP):
