Start Base

To set up the connected receiver for a base occupation.

This dialog has the special layout for setting up the base for PP Kinematic and PP DGPS surveys.


To set up and start the base occupation.

  1. Enter the name of the Point where the Base receiver is located. It can be chosen from the map or the list of the job points, or can be entered manually.
  2. Select the Code for the point from the drop-down list. If required, set a string. Click to set the point's attributes. More...
  3. The coordinates of the base point in the selected coordinate system will be shown.
  4. You can enter the measured coordinates of the current point. To measure the current position:
  5. Click the Start Base button to start the receiver as the Base that transmits the correction data. Once pressed the button changes to the Stop Base button.

  6. Note: If you start the base with a UHF radio and only for the first time in the job, clicking the Start Base button initiates the Quick Radio configuration to quickly set up the UHF radio for data transmission. Learn more about how MAGNET Field controls Quick Radio.

  7. The Duration field displays the time the receiver logs data to the raw GNSS data file for the Post-Processed RTK.

Click to open a pop-up menu with the following options. More...

Click to open the Post-Processing dialog and review raw data logging settings in surveys with post-processing.


Important note:
In specific RTK and DGPS configurations, when starting the base, you can receive the following warning:

"Base station data was updated from corrections. Your rover firmware does not recognize the base antenna. Make sure that height of measured points is correct."

If you encountered this situation:



Start Base (PP Kinematic / PP DGPS)

To set up and start the base occupation in Post-Processed Kinematic or Post-Processed DGPS survey.

  1. Enter the name of the Point where the Base receiver is located. It can be chosen from the map or the list of the job points, or can be entered manually.
  2. Select the Code you want assigned to the point. It will be included in the raw GNSS data file. Click to set the point's attributes if required. More...
  3. Enter the antenna height and set the type of height measurement( vertical or slant). You can edit the antenna type, the value of the antenna height, and the type of height in the Antenna Setup dialog.
  4. Click the Start Base button to start the logging of data into the raw GNSS data file. Once pressed the button changes to the Stop Base button.
  5. The Duration field displays the time the receiver logs data.

Click to open a pop-up menu with the following options. More...

Click to open the Post-Processing dialog and review raw data logging settings.



Start Base pop-up menu

The pop-up menu can contain the following options:

Status

Config Radio/Config GSM depends on the modem type for the survey

Multi Base available for RTK with CMR+ format of correction data

Grid to Ground available if starting the base in a grid coordinate system


Multi Base

For Multi Base mode in RTK survey, all Base receivers must be configured to transmit at the same frequency and must transmit CMR+ format corrections. The Rover receiver must be configured to receive only CMR+ messages.

To set multi base mode for surveying:

  1. From Base Station ID, select the identifying number of the base, which is sent as part of the CMR+ messages. Each base in a network must have a unique ID.
  2. From Transmit Delay, select the signal transmission delay from the current base. This parameter is set to ensure that the radio signals from multiple bases do not overlap. Each base should be set at least 250 milliseconds apart from any other. (At least 500 milliseconds for data transfer rates less than 9600 bps.)
  3. Select the Use Multi Base check box to enable multi base mode.
  4. Click to save the settings and to return to the Start Base dialog.


Quick Radio

The Quick Radio functionality enables quick configuration of a UHF radio channel for data transmission.
