RTK

The RTK tab allows you to configure how the receiver will broadcast real-time kinematic corrections.

Note: The options presented within this dialog box are receiver specific and will vary.

Note: For effective base/rover communications, each receiver must be capable of achieving the same settings of the other receiver.

• Device: This list contains the supported methods that send RTK corrections. The resulting configuration settings (wrenches button) will vary based on the selected device type.
  More Information

  Note: For additional information on the Devices below, please refer to the discussion under GPS Rover - RTK.

  Based on the capabilities of the selected receiver, common device types might include:

  • Internal Radio: For receivers equipped with built-in radios, often using UHF- and/or SSRfrequencies, the radio can be set up to transmit location corrections and are typically reach up to three miles (five kilometers) between the base and rover. Such devices are commonly used in rural areas.

    Note: Using UHF radio signals to broadcast position corrections may require governmental (e.g. FCC) approval.

  • Receiver GSM: For receivers that contain integrated cellular communication capabilities, the cellular modem can be configured to broadcast location corrections. This device type is commonly used where reliable cellular signals occur at both the base location and at the rover location(s).
  • Receiver WiFi: For receivers that can be configured as a WiFi broadcaster, positional corrections can be conveyed via its WiFi signal. This is commonly used for relatively short communication distances as might be needed between a base receiver and an RTK-equipped UAV (drone) controller.
  • Data Collector GSM or WiFi: As needed, positional corrections can also be conveyed via the cellular or WiFi signal of the data collector (controller).

    Note: With this option, the GPS base receiver and the controller must remain in effective communication distance with one another.

  • Cable or Generic Device: When selected, the user will need to specify the Port, Baud, Parity and/or Stop Bits of the device (commonly an external radio) that is connected to the receiver.
  • Do Not Configure: When selected, no positional corrections will be transmitted.
• Network: This list allows you to configure and connect to various networks.
  More Information

  Not every device will have a configurable network. For those that do, common options include:

  • TCP Client: For sending base station corrections to a local Extranet address using TCP messaging.

    Note: The IP Address:Port can be viewed under the Monitor/Skyplot - Quality tab.

  • UDP/IP Direct: For sending base station corrections to a local Extranet address using UDP messaging.
  • TCP/IP Network: For sending base station corrections to a specific Internet address and port using TCP messaging.
  • UDP/IP Network: For sending base station corrections to a specific Internet address and port using UDP messaging.
  • Listen-Listen: For sending base station corrections to Carlson's low-latency Listen-Listen network through Carlson-assigned base/rover port numbers.
  • Local NTRIP: For sending base station RTCM corrections to a local Extranet port with additional login/access credentials.
  • Dynamic DNS: For sending base station corrections to a user-defined host name.
• RTK Port: Indicate the port on the receiver from which RTK corrections will broadcast. This option will default in most cases, but may need to be set when a cable connection is used.
• Baud: Indicate the transmission speed at which base station corrections should be sent.
• Message Type: Select the RTK message type that you wish to broadcast.

Note: It is recommended to go left to right through the tabs, from Current to Comms to Receiver to RTK, to ensure that all settings are correct, especially when configuring a new receiver for the first time.
