mrpt::hwdrivers::CNTRIPEmitter Class Referenceabstract

Detailed Description

This "virtual driver" encapsulates a NTRIP client (see CNTRIPClient) but adds the functionality of dumping the received datastream to a given serial port.

Used within rawlog-grabber, along CGPSInterface, this class allows to build a powerful & simple RTK-capable GPS receiver system.

Therefore, this sensor will never "collect" any observation via the CGenericSensor interface.

See also the example configuration file for rawlog-grabber in "share/mrpt/config_files/rawlog-grabber".

PARAMETERS IN THE ".INI"-LIKE CONFIGURATION STRINGS:
-------------------------------------------------------
[supplied_section_name]
COM_port_WIN = COM1 // Serial port where the NTRIP stream will be dumped to.
COM_port_LIN = ttyUSB0
baudRate = 38400
#transmit_to_server = true // (Default:true) Whether to send back to the TCP/IP caster all data received from the output serial port
#raw_output_file_prefix = raw_ntrip_data // If provided, save raw data from the NTRIP to a file, useful for post-processing. In this case, not having a serial port configured (commented out) is a valid configuration.
server = 143.123.9.129 // NTRIP caster IP
port = 2101
mountpoint = MYPOINT23
//user = pepe // User & password optional.
//password = loco

◆ appendObservations()

void CGenericSensor::appendObservations ( const std::vector< mrpt::utils::CSerializablePtr > &  obj)
protectedinherited

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

mrpt::obs::CObservationGPSPtr o = CObservationGPSPtr( new CObservationGPS() );
o-> .... // Set data

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.
