Configuration parameters of the GNSS receiver’s real-time system.

 

 

 

 

Radio modem: This box is activated for Base RTK type styles, so that the real-time parameters of two different radios may be configured.

 

Mode: Specifies the work mode for real-time, which can be Phase Differential (RTK – Real Time Kinematic) or Code Differential (DGPS = Differential Global Positioning System). See glossary of terms.

 

Format: Protocol used for the radio link. The possibilities depend on the model of the GPS receiver configured.

 

Corrections: Allows one to mainly select the type of DGPS corrections used by the receiver. In some cases, it also combines with RTK mode.

 

Protocol: Indicates the channel used to send/receive corrections. 3 possibilities are offered:

 

-: Conventional UHF radio.

GSM: Mobile telephony network. GSM.

NTRIP: Mobile telephony network. GPRS. NTRIP Protocol.

 

The Details button allows one to configure each type’s additional parameters.

 

  

 

If GSM is selected, it will be necessary to enter the PIN number of the receiver modem’s SIM card and the telephone number (Station Number) which must be called from the rover. The Connection Time section allows one to indicate the time in minutes past which the connection will be reinitiated. This option is useful to save on costs, as there are companies that offer a flat rate up to a certain number of minutes.

 

For the connection via NTRIP the telephony provider data must be indicated with whom the service was contracted (User, Password, Number and APN), the PIN number of the SIM card, the IP address and the connection Port and, finally, the User name and Password for accessing the NTRIP server.

 

The Operator and NTRIP lists contain the most usual telephony providers and NTRIP servers in Spain, respectively. Every time data from either of them are selected, the fields which correspond with the predetermined values will be automatically completed. The dropdown menu of the title bar provides options which allow new NTRIP servers and operators to be edited and created.

 

          

 

Position Update (Hz):  Frequency with which the receiver refreshes the position. A list containing the available values according to the receiver’s model and the options acquired is shown.
